All available data on the stratigraphic range, palaeobiogeographical distribution, and systematics of the blastozoan genus Ascocystites (Echinodermata) are reviewed and discussed. Its stratigraphic extent appears to be limited to the Darriwilian–Sandbian by: 2.

Abstract. Echinoderms underwent an initial radiation into marine shelf environments in the Early to Middle Cambrian. Within about 45 million years, nine new classes of echinoderms (as recognized in an evolutionary classification) appeared suddenly in the fossil Cited by:   Testing for homologies in the axial skeleton of primitive echinoderms.

The non-crinoid pelmatozoans, commonly called blastozoans (Fig. 2), were most diverse and abundant during the Middle Ordovician, but crinoids reached their acme somewhat later, during the Early Carboniferous.

By the end of the Permian, both crinoids and non-crinoid pelmatozoans suffered a catastrophic decline (Fig. New wrs. - untrimmed.
