Scyphocrinus, paleozoic crinoids, are among the most well-known large pelagic crinoids. They are animals, not plants. Today there are still crinoids in the oceans called Sea Lilies.
These atypical animals were made of a very long stalk, like a long stalk attached to a root that floated on the surface like a buoy. They therefore moved to the sandstones of the current, feeding on organic particles suspended in water. in the Paleozoic, crinoids could form true underwater “prairies”. When he died, he could sink, sediment himself whole and then fossilize.
