Rare Pre-Cambrian Large Partial Dickinsonia costata Preserved in Quartzite. One of the most important enigmatic animals of the Pre-Cambrian fossils of South Australia is Dickinsonia costata. Preserved in the 560 million year old red Quartzite in the Flinders Range, about half of this rare and important fossil that is quite large at 4 x 3" on a 5½ x 4" red Quartzite matrix. Dickensonia was an ovoid, segmented animal without eyes or a mouth that lived on the ocean floor that fed on algae blooms and was able to move over the algae fields in feeding. It was one of the very first animals that was capable of movement. There is still much debate as to what it was and what it is related to in the modern oceans, everything from some kind of flat worm to some strange quilt-like animal that has no descendants.
