Crinoid habitat.

Platyceratidae is an extinct family of Paleozoic sea snails, marine gastropod mollusks. This family may belong in the Patellogastropoda or the Neritimorpha.

An analogy would be today's crinoids, which mostly exist as deep water species; in the Paleozoic era, vast 'forests' of crinoids lived in shallow near-shore environments. Some of the genera of trilobites during the Carboniferous and Permian periods include: Archegonus (Early to Middle Carboniferous) Hesslerides (Middle Carboniferous)Blastoid. Blastoids (BLAS-toyds) are extinct, stalked, invertebrate animals that were related to crinoids. Like crinoids, blastoids had an upward-facing mouth near the top of the body (theca). They differed from crinoids in that, instead of true arms, blastoids had long, delicate appendages called brachioles. These caught suspended particles on ... Chapter contents: Echinodermata –– 1.
