Lot 639		Carcharodon megalodon Shark's Tooth. Even though Carcharodon megalodon was the largest shark that ever lived growing to more than 50 feet in length most of the teeth found are only 3-4 inches in length. Teeth over 5 inches in length are in great demand and the magic number is a full 6 inches which is the size that every collector aspires to own. This immense 6 inch long 5 inch wide 15 million year old Carcharodon tooth was found in the muddy river waters of South Carolina. Estimating the length of a shark at about 10 feet in length to every one inch of tooth, this behemoth would be 60 feet long. This huge tooth has fairly complete green-gray enamel on both the front and back but does have some repair of minor chipping on the blades and about 10% restoration on the front root. This is an opportunity to purchase a really huge shark's tooth without paying well over $1000. Comes with a custom black stand for display. Add $15 for domestic shipping. Estimated Value $550 - 750. View details and enlarged photo	Realized $800
Lot 640		Collection of Fossilized Shark, Fish and Mosasaurs. This collection of over 85 Shark, Stingray, fish and mosasaur teeth come from the Moroccan Phosphate mines of Khouribga. There are 25 different species in this collection that are mounted and labeled as to species in a custom wooden case that is 19.25 x 11.5 inches. These complete fossil teeth are between 45-70 million years old and range in size between .5 inch to 2 inches. This important collection took many hours to put together and reveals the diversity of sea creatures in the warm seas of ancient Morocco with a wide variety of different shaped teeth and species. Allow $30 for domestic shipping. Estimated Value $375 - 500. View details and enlarged photo	Unsold
Lot 641		Complete Knightia Fish Fossil in sandstone. From the Green River Formation, Eocene, Wyoming. In a custom wooden frame. Size of fossil: 5¼" x 9". These fish are relatives of the modern day herring. They average four inches in length. Knightia are present in over sixty per cent of the fossil found. In some place there appear to have hundreds in one layer, indicating some kind of mass morality. These fish were probably on the lower level of the food chain, eating algae or small one celled animals. Estimated Value $100 - 150. View details	Realized $66
Lot 642		Complete Mounted Dinosaur. This 22 inch long important dinosaur Jeholosaurus is between 130-135 million years old from Central Asia, has over 80% real bone and has been professionally mounted in a lifelike walking position. All of the small delicate bones have been micro-drilled with small rods inserted inside the bones to give a realistic 3D free standing specimen with the only visible rods being at the bottom of the feet. The bone quality is excellent with the only restoration done on the ribs and some of the small neural spines along the back and tail. The important 2.5 inch skull is complete with real teeth on both the upper and lower jaws on one side and several tips of teeth visible on the other side of the skull. There could be some more teeth under this other side but they may be obscured because the skull has shifted a little bit to one side. The eye of the skull is huge being one inch in diameter and even though this specimen is a juvenile, it probably indicates that Jeholosaurus was a nocturnal dinosaur that hunted insects at night. The large back legs with large feet show that Jeholosaurus was a very fast running dinosaur. It was bipedal and the fingers on the hands are displayed in a natural curved postion with sharp little claws which they may have used to dig in the ground for insects. Jeholosaurus belongs to a little know taxa of dinosaurs know as Heterodontosauridae. These small supposedly plant eating dinosaurs are very eary Ornithipods and are little understood because so few of them have been discovered. Just recently a slightly older but similar Heterodontosauridae known as Tianyulong was found in Liaoning, China as is important as it was clearly feathered with short small feathers. This means that its slightly later ancestor Jeholosaurus would also have been feathered. This is extremely important as no Ornithipod or plant eating dinosaur had ever been found that had feathers. Only some theropod, meat eating dinosaurs have been found to have feathers. Thus, Jeholosaurus is a missing link animal that bridges the feather gap of Ornithipod and Theropod dinosaurs. Jehosaurus is from the early Cretaceous of over 130 million years ago and was found in the tuffaceous volcanic sandstone of the lower Yixian formation in Liaoning Province of Central Asia. Even the teeth of Jeholosaurus look like a cross between a meat eating and plant eating dinosaur with sharp pointed teeth in the front of the jaw and flat teeth in the rest of the jaw like a plant eating dinosaur. Perhaps they were omnivores eating both plants and insects and possibly small lizards. This 22 inch long 11 inch high juvenile Jeholosaurus has been mounted on a 10.5 x 4 inch wooden base for display and a glass or acrylic clear case can be easily obtained for display if desired. The dinosaur comes apart in seven pieces for easy transportation and examination. The skull can be easily taken on and off for study. This is an important opportunity to buy a complete dinosaur at a reasonable price as very few collectors can ever hope to own a real complete dinosaur without paying hundreds of thousands of dollars.

Lot 643		Complete Psittacosaurus Skull. Psittacosaurus is a very important dinosaur that lived between 120-130 million years ago in Liaoning Province, Central Asia. Psittacosaurus is important as being the oldest ancestor of the famous horned dinosaurs such as Triceratops. Psittacosaurus did not have horns but did possess a horned beak and bony Jugals (back of the upper jaw) which are characteristic of only ceroptopsian (horned) dinosaurs. Psittacosaurus is the most studied of all dinosaurs because it is known from all stages from hatchling to adult. With eggs about 3 inches long, the hatchlings were about 6 inches long and adult Psittacosaurs were over 4 feet long. This important juvenile dinosaur skull is 4.25 x 3.25 inches completely removed from its hard stony matrix except for the back of the skull which was left for stability. More than 10 hours of careful detailed work was required to remove the hard stone matrix from inside the skull. It is a good skull with solid bone and just slightly distorted with all of the teeth restored. The important jugals, fenestrae and eye holes are completely cut out and show excellent detail. This impressive dinosaur skull has been mounted on a 5 x 3 inch custom black wooden stand for display. Add $25 for domestic shipping. Estimated Value $1,400 - 1,700. View details and enlarged photo	Unsold
Lot 644		Dinosaur Skin With Soft Tissue. Dinosaur skin is the rarest and most coveted of dinosaur fossils because of its extreme rarity being preserved only under extraordinary conditions. The dinosaur had to have been completely covered by fine mud sediments probably in a large river delta within a day or so after dying to avoid bacterial breakdown of the skin and soft tissue which would occur immediately. This type of extreme condition may have occurred in a massive flood. The skin texture was impressed in detail in the soft clay forming a natural mold which was later filled by more muddy sand creating a natural cast and remained intact for over 65 million years even after the skin and other soft tissue was destroyed by bacteria. This large section of dinosaur skin is from the back of the hip or tail section of an Edmontosaurus duckbilled dinosaur and is between 65-70 million years old and was found along with some fragmented Edmontosaurus bones in the Hell Creek Formation of Montana. Also, soft tissue has also been fossilized along with the skin. The soft tissue could be muscle or glands but it is something that was just beneath the skin. The answer might be coming soon as a more complete Edmontosaurus with soft tissue has been found and was featured on a National Geographic Show titled "Dinosaur Autopsy " with a book coming out later this year. This large section of matrix is 10.5X7 inches and has deep very distinct skin impressions on both sides of the limestone rock. The best detailed skin is 4X4 inches showing excellent detail and colorwith a large 8X2 inch skin section curving beneath it. Also present on the bottom of this 8X2 inch skin section is a 2.5X2 inch dark brown imprint of the muscle or gland that was present just beneath the skin. On the back of the slab is another 5X5 inch long skin impression area that varies in thickness from 1-3 inches. All of the color is original just as found when the rare specimen was broken out of a larger piece of rock. The Dinosaur Autopsy show called their find the most important of the decade and an offering of dinosaur skin with soft tissue preservation may never be offered for sale again.

Lot 645		Dinosaur Three Egg Partial Nest. These three large complete unhatched Duckbill dinosaur eggs are 70-80 million years old 6-6.5 inches in diameter and of museum quality with 75- 90 percent of their original shell intact. These eggs are completely original with grayish and brown fossilized eggshell nicely contrasting the original red brown matrix. We do not know what Duckbill species these eggs belong to as no embryonic bones have every been found in the Duckbill dinosaur eggs, but being the largest Duckbill egg at a gigantic 6.5 inches in length (most eggs being 5-5.5 inches long), they might belong to the huge Duckbill dinosaur Shantungosaurus which reached more than 50 feet in length and has been found in the same area in the Henan Province of China. These museum quality dino eggs make an excellent display having much more original egg shell than normally found and resting on the original reddish brown limestone matrix. Dinosaur eggs are becoming hard to locate and rising sharply in value. Add $40 for domestic shipping. Estimated Value $2,000 - 2,500. View details and enlarged photo	Unsold
Lot 646		Double Keichousaurus Skeletons. Keichousaurus hui was the 240 million year old ancestor from Guizhou Province, China of the famous long necked sea reptiles Plesiosaurus which was made famous as possibly being the mysterious Loch Ness monster. Keichousaurus was older than any dinosaur, lived in the ocean and had a long, flexible neck, tiny sharp teeth, webbed feet and a tail as long as its neck. This 10 x 7.5 inch light gray slab contains two original black Keichousaurs 7 and 6 inches long adults both possessing excellent 3-D well defined bones. The larger 7 inch specimen is virtually complete buried upside down with two legs and digits and perhaps parts of the other two legs still buried under the matrix. The top specimen is 6 inches long buried with the dorsal side up and is somewhat disarticulated with only one leg visible. Both specimens possess excellent skulls with one preserved upside down with the delicate bottom jaws preserved and the other with the top view with even one of the small pointed black teeth visible. What makes this specimen so desirable is its originality and its highly esthetic appearance with one specimen lying on top of the other at different heights on the original matrix which has a series of concentric curved lines that indicate the different layers of deposit. Add $20 for domestic shipping. Estimated Value $700 - 1,000. View details and enlarged photo	Realized $504
Lot 647		Five Therizinosaur Dinosaur Eggs. This original partial nest of five dinosaur eggs is very distinctive in being from the rare and poorly understood class of dinosaurs known as Therizinosaurs. Therizinosaurs were some of the strangest looking dinosaurs having some features of a plant eating dinosaur and some features of a theropod dinosaur. They had a small skull on a long neck with a large gut which resembled a plant eating dinosaur, but also were bipedal, had filamentous feathers, and extremely large hand claws like a theropod dinosaur. Embryos have been found in some of the eggs of this shape so we know that they belong to this strange dinosaur which probably was a plant eating dinosaur although some paleontologists think that the large claws may have been used to tear apart large termite mounds. The five eggs are 3 x 3 inches long and are still contained in their original 11 x 7 inch red limestone matrix as deposited between 80-90 million years ago in the Xixia Basin of the Henan Province, China. The eggs are in excellent condition being unhatched varying between completely inflated to one egg that is mostly flattened. Even though the shells of Therizinosaur eggs are very thin, these eggs contain between 60-100 percent of their original shell. These eggs are completely original as found and a lot of the shell is still buried beneath a thin layer of red calcite. Even the egg with about 60% shell appears to have more shell beneath the stone matrix. Therizinosaur dinosaur eggs are in great demand and much rarer than the usual Hadrosaur and even the Oviraptor dinosaur eggs. Allow $50 for domestic shipping. Estimated Value $1,750 - 2,250.

Lot 648		Giant Mammouth Tooth. Intact marbled molar. A colorful and extremely interesting natural fossil. Size: 10" x 3". Weight: 15 lbs. Estimated Value $500 - 750. View details and enlarged photo	Realized $132
Lot 649		Green River Fish and Palm Frond. Green River Wyoming is famous for its exquisitely fossilized 50 million year old fish and leaves. These are usually found separately because most of the fish are found in deeper water than the plants which are mostly found close to the ancient lake shore. Rarely are they found together as on this 14 x 13.5 inch limestone plate. This plate contains a large 15 inch section of a palm frond, a 2 inch leaf and two Knightia fish swimming below the palm frond. The two Knightias (related to herring) are 4 inches and 3 inches long complete with excellent bones and fins. The medium to dark brown fossils are nicely contrasted against the cream colored limestone matrix. Add $30 for domestic shipping. Estimated Value $550 - 700. View details and enlarged photo	Realized $480
Lot 650		Important 123 Million Year Old Bird Fossil With Feathers. This small 4.5 inch long primitive enantiornithine bird, Liaoxiornis delicatus was alive in the cretaceous period 122-124 million years ago. The only significantly older bird is Archaeopteryx from Germany at 150 million years old. This nearly complete bird from the Liaoning Province of Northeastern China is quite remarkable in its magnificent preservation. Birds have very delicate light weight bones that are only preserved under very special circumstances such as the rapid burial that occurred over 122 million years ago when an enormous volcanic eruption quickly killed and buried in ash this small toothed bird. The preserved detail is truly amazing with an excellent skull missing only the tip of its beak, delicate rib bones, small hand and feet bones and claws and even some black feather impressions surrounding the neck, tail, body and wings. It was believed that we would never know the color of a dinosaur or fossilized bird but recently it was discovered from fossilized feathers such as those on this specimen that microscopic melanosomes (pigment bearing organelles within feathers) can reveal the actual color when the bird or dinosaur was alive. The shape of the melanosomes is compared to the shape of melanosomes in modern birds and the color of the fossilized feathers is assumed to be the same if the melonosome shape is the same. Dark feather impressions such as those on this fossil bird have been found to be black or gray in living birds. This important bird fossil is nicely centered on a 6.5 x 5.5 inch soft tuffaceous stone matrix which is intact and not repaired like most encountered. This important rare bird skeleton is enclosed in a 12X8 inch riker mount for display and protection. A much younger and less detailed 50 million year old Green River bird recently sold to a museum for $15,000. Add $50 for domestic shipping. Estimated Value $3,000 - 4,000. View details and enlarged photo	Realized $3,120
Lot 651		Largest Egg Known. The extinct flightless bird Aepyornis maximus produced the largest egg of any animal that ever lived including dinosaurs. The egg in this lot is 13.5 inches by 9 inches and 29 inches in circumference. This was the equivalent volume of 10-12 Osterich eggs or 160 chicken eggs. Aepyornis is commonly known as the elephant bird, a name that originated from Marco Polo's account of the giant bird in 1298. He described the ten foot tall Aepyornis that weighed over half a ton as having talons large enough to seize an elephant. Aepyornis was the largerst bird that ever lived and only became extinct in the middle of the 17th century. Aepyornis only lived on the island of Madagascar and the shell from this bird that has been reconstructed to form this huge impressive egg is 10,000-20,000 years old and was found in the southern sands of Madagascar. Great care and time was spent in matching the sizes and curvature of the egg fragments to put the egg back to its normal shape and size. The egg is quite solid and stable. There are only about a dozen unbroken Aepyornis eggs known most in museums with one selling at auction for over $25,000. This huge egg comes perched on a hand carved wooden stand for a very dramatic display. Add $40 for domestic shipping. Estimated Value $1,500 - 2,000. View details and enlarged photo	Realized $1,260
Lot 652		Merycoidon Mammal Skull. Merycoidon gracilis was a strange 30 million year old mammal from the extinct oreodont mammal group that has no modern relatives and had some features of a pig and some features of a deer. This original large 7.5 x 4 inch long skull is completely original with no restoration and complete except for the snout and a small portion of the back of the jaw. Some of the skull bones are slightly cracked just as found in the hard stone matrix with no filling repair. Almost all of the teeth are present except for a couple of teeth in the upper jaw and one incisor. The teeth are a lovely brown color that nicely contrasts against the light cream colored skull bone. This completely original fossil is as found with just the overlaying rock being carefully removed was found on privately owned land in the White River Badlands formation of Sioux County, Nebraska. This early mammal skull comes mounted on a 8.5 x 5 inch black wooden stand. Allow $25 for domestic shipping. Estimated Value $450 - 600. View details and enlarged photo	Realized $360
Lot 653		Moroccan Schloenbachia Large Chambered Ammonite. A beautifully prepared fossil ready to be displayed Dia: ½". Estimated Value $400 - 600. View details and enlarged photo	Realized $108
Lot 654		Oviraptor Dinosaur Egg. This original nearly fully inflated unhatched Oviraptor egg is 70-80 million years old from the Djadokhta formation of Ukhaa Tolgod of Mongolia. This egg was found in the Gobi desert and is 6 inches long and belongs to the largest of the two Oviraptor species called Citipati to distinguish this difference from the other smaller species. Citipati Oviraptorids were made famous by the nest of eggs with the mother Citipati sitting on top of the eggs in a brooding position. This famous specimen is displayed in the New York Museum of Natural History and was discovered in 1995. It was revolutionary to discover a dinosaur sitting on top of its eggs like a bird and only later was it discovered that Oviraptors such as Citipati also had feathers like a bird. Citipati eggs are ratite in texture and have a very thin shell which is why they are rarely found complete. This unhatched egg has black and gray colored eggshell with an excellent shape. The top side is nearly completely covered by somewhat worn grey eggshell with about 25% of top covered with more detailed black eggshell with its typical ratite pattern. The backside of the egg has about 35% mostly detailed black shell with perhaps more shell still hidden under the original reddish brown matrix. This egg could contain some embryonic bones inside as typically, about 20% of the unhatched Oviraptor eggs contain some embryonic bones. The bones are always disarticulated and usually are jumbled together in a small area. This important dinosaur egg comes with an illusion stand for display. Add $30 for domestic shipping. Estimated Value $600 - 800. View details and enlarged photo	Unsold
Lot 655		Pair of Dinosaur Footprints. This pair of rare fossil dinosaur footprints are a dark brown in color on a 13 x 9 inch light gray shale slab containing footprints from two different bipedal theropod dinosaurs Eubrontes and Grallator. The huge Eubrontes footprint is 12 inches long and 5.5 inches wide with all three toes deeply impressed up to 1 inch above the matrix. There is a clear claw impression on the middle toe but only about 25% of the left toe is on the matrix. Eubrontes is the name of the footprint not the name of the dinosaur that left it. The largest known dinosaur to have inhabited the Connecticut Valley of Massachusetts(near Holyoke) 200 million years ago was Dilophosaurus (made famous by the movie Jurassic Park). The footprint matches both the size and shape of the twenty foot long Dilophosaurus. The second smaller 6 x 4 inch foot print is know as Grallator which exact species of dinosaur that left it is still unknown although it is similar in shape and size to the meat eating dinosaur Podokesaurus, a medium sized theropod, whose partial skeleton was found in the same area. These footprints are the more highly valued positive raised impressions which preserve the most detail of the dinosaur stepping in soft mud preserving some pad and claw details. All of the theropod dinosaur footprints preserve just three toes as theropods walked on their 2nd, 3rd and 4th toes which correspond to the three middle human toes. Add $25 for domestic shipping. Estimated Value $600 - 900. View details and enlarged photo	Unsold
Lot 656		Russian Aberrant Ammonite. Most ammonites have the familiar tight spiral shape that is so familiar, but some ammonites known as aberrant (heteromorphic) ammonites began to straighten out forming a variety of odd interesting shapes. Why this happened after more than 200 million years of having only the spiral shape is unknown, but some species did change 70-120 million years ago. This large 9 inch long ammonite from Russia (Ancyloceras matheronianum) is over 100 million years old and has an unusual mostly uncoiled shape that started out with a tight curl and then began in uncoil as it grew larger. This large and spectacular ammonite is nearly complete with just the smallest inner curls missing with its original white mother-of-pearl shell coating fossilizing to an iridescent brown and tan with splashes of white still present. This museum quality and rare ammonite is nicely contrasted against its original black slate matrix. Allow $20 for domestic shipping. Estimated Value $1,100 - 1,400. View details and enlarged photo	Unsold
Lot 657		Spinosaurus Foot Claw and Tooth. Made famous in "Jurassic Park III" as the dinosaur that killed a T-Rex, the enormous theropod dinosaur Spinosaurus with a huge sail on its back remains an enigmatic dinosaur as no even remotely complete skeleton has been found and the only partial skeleton was destroyed in World War II. Spinosaurus is mostly known from its teeth which are fairly common but usually broken and ugly. Claws are rarely found and big claws such as the 3.6 inch complete museum quality foot claw showing all of the bold grooves with a perfect tip with just some crack. Claws are much rarer than teeth because dinosaurs could replace their teeth but not their claws. Also included is a gigantic quality 5 inch long tooth that was found in two pieces and put back together with excellent brown enamel, a partial 2 inch root with just a little tooth wear and minor chipping on the tip. This 80 million year old dinosaur claw and tooth were found in the Kem Kem Valley near Taouz, Morocco. These museum quality fossils are housed in a 8X6 inch Riker mount. Allow $20 for domestic shipping. Estimated Value $1,200 - 1,500. View details and enlarged photo	Unsold
Lot 658		Symphysurina, the Mustache Trilobite. At 11.5 inches long and an enormous 13 inches wide, this new species of Asaphus trilobite Symphysurina known as the moustache trilobite because of the large curved spines at the end of its Cephalon (head) is one of the very largest trilobites that ever lived. It was a predatory trilobite that swam in the warm waters of Morocco 475 million years ago. This very dramatic black trilobite is nicely contrasted against its light brown 15 x 16 inch limestone matrix and is complete with its small eyes visible and only minor restoration of the long curved head spines. This is an opportunity to acquire a rare trilobite that is also very impressive looking and lacking from most collections. Add $30 for domestic shipping: $30. Estimated Value $900 - 1,200. View details and enlarged photo	Realized $780
Lot 659		Three Fossil Feathers and Insects in Amber. This large 2.75 x 1.75 inch clear and loaded amber nugget contains three large bird feathers that are joined together in a long 1.6 inches grouping. Bird feathers preserved in amber are extremely rare and these three feathers are very clear with their delicate veins and barbs well detailed. As an extra bonus this interesting piece of amber is absolutely loaded with insect inclusions including ants, a leafhopper, a winged termite with excellent wing detail, a spider, rove beetles, advanced flies, fungus gnats and many reddish circular globs of fungus. Many hours can be spent examining this loaded piece of amber with a low power magnifying glass and discovering new insects and details. The absolute age of young Colombian amber or copal cannot be determined as amber itself cannot be tested and dated, but from the color and hardness of the golden Colombian nuggets, experts suggest their age to be at least 1-5 million years old or older. Allow $15 for domestic shipping. Estimated Value $800 - 1,200. View details and enlarged photo	Unsold
Lot 660		Triceratops Brow Horn. Triceratops with its two long brow horns and living at the same time as T-Rex is one of the most popular dinosaurs. This 16 x 6 inch brow horn is very large and from a mature Triceratops. The horns of a Triceratops are never found without cracks and are usually found in pieces. This is an excellent dark well detailed brown specimen that was found in three pieces that fit together almost perfectly and with a near complete tip that had just a little wear. The horn has no restoration with an interesting surface that resembles fossilized wood. This is a horn core which in life would have been covered with keratin (like our fingernails) and would have been about 30% larger. This excellent large and impressive heavy display fossil is 65-66 million years old and was found on a private ranch in Montana. The horn comes with a plastic display stand. Allow $40 for domestic shipping. Estimated Value $2,000 - 3,000. View details and enlarged photo	Realized $1,680
Lot 661		Trilobite Mass Mortality Plate. Some natural disaster occurred 480 million years ago to bury these 15 trilobites in their living position. These spectacular 3-D trilobites are from the Ordovician Kaoua formation of Southern Morocco. These spectacular mostly complete black trilobites, Omnia superba are nicely contrasted against the cream colored 10 x 6 inch light brown stone matrix. Ommia superba is a very distinctive looking trilobite with a bulbous "nose" on its head (cephalon) as well as an interesting dimpled pattern on the front edge of the head. Also, it is considered a spiny trilobite as it has two long spines extending back from its head to the rear (pygidium) of its three part body. All 15 of these 100% original trilobites look very life-like as if they are crawling on the rolling ocean bottom. Add $25 for domestic shipping. Estimated Value $700 - 1,000. View details and enlarged photo	Unsold
Lot 662		Two T-Rex Teeth. These two T-rex teeth were found very close to each other in an ancient river or lake bed on a private ranch in the 65-67 million year old Hell Creek Formation of Montana. The larger 2.75 inch long T-rex tooth is not only large but also pristine with an excellent tip with just a very small amount of natural feeding wear and sharp serrations with no repair. Most T-rex teeth found have feeding wear on their tips which occurred when the T-Rex was still alive. The enamel has a few cracks in it as found and is a lovely tan to brown color. The tooth is rather thick, has sharp squared serrations which define it as a T-Rex, and even shows a very defined indentation at the root level on one side which is from a replacement tooth that was already growing behind this tooth when it was broken off when the T-Rex was feeding. The second 1.5 inch completely intact tooth has sharp serrations and has a matching color and exactly fits into the tooth indentation of the larger tooth. All T-Rex teeth are shed teeth except the very few that are found with the dozen or so partial skeletons that have been found. All T-Rex teeth are in great demand, but those very few that are not broken and repaired are rarely encountered. Both of these T-rex teeth are housed together in a 8 x 6 inch Riker mount. Allow $25 for domestic shipping. Estimated Value $4,500 - 5,500. View details and enlarged photo	Realized $3,600
