Crinoid fossils. These are Scyphocrinus elegans crinoids from the Silurian/Devonian period (about 440-360 million years ago). Crinoids are marine echinoderms that appear as early as the Ordovician period (500 million years ago). These crinoids have stalks by which they would attach themselves to the seabed, capturing food with feathery arms that formed a cup (seen at lower right and upper centre).
China || Chengjiang Fossil Site. A hilly 512 ha site in Yunnan province, Chengjiang’s fossils present the most complete record of an early Cambrian marine community with exceptionally preserved biota, displaying the anatomy of hard and soft tissues in a very wide variety of organisms, invertebrate and vertebrate. They record the early establishment of a complex marine ecosystem.
