Crinoids. Crinoids are echinoderms, related to sea urchins and sea stars. These invertebrate animals feed by using their arms to filter food out of the water. Most are attached to the sediment by a stalk that ends in a root-like structure called the holdfast—some forms, however, are free floating.Periode Devon Awal adalah salah satu periode geologi yang terjadi selama era Paleozoikum, yang berlangsung sekitar 419 hingga 393 juta tahun lalu.

Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as 9,000 meters (30,000 ft). Adult crinoids are characterised by having the mouth located on the upper surface. Trilobite, any member of a group of extinct fossil arthropods easily recognized by their distinctive three-lobed, three-segmented form.

They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows.
