Rare Skin Impression Of A Hadrosaur Dinosaur. The rarest of all dinosaur fossils are those of skin impressions because soft tissue is not fossilized except under extraordinary circumstances, such as a dinosaur dying in a river or lake and being quickly partially covered in mud. Such must have been the case for the duckbill dinosaur Prosaurolophus maximus that was the source for this 75 million year old 3" x 2 ½" skin impression fossil in The Judith River Formation of Montana. We can never determine the color of the skin, but the texsture is clearly visible in this fossil with a grouping of small hexagonal depressions found in the rock. The skin would have been bumpy and leathery like that found on an alligator. This important fossil is housed in a 6" x 5" Ryker box for protection. Add $15 for domestic shipping.
Estimated Value $500 - 750.
