Eocrinoids were an early group of echinoderms that lived between the Early Cambrian and Late Silurian periods. They had a stalk which attached them to the bottom of the ocean via a holdfast and were benthic suspension feeder which used their arms to move particles of food towards a mouth. They are believed to be ancestral to many other groups including crinoids and blastoids.
