Abstract

New flexible crinoids referable to Taxocrinus Phillips and Onychocrinus Lyon and Casseday are made known from Carboniferous (Mississippian, Chesterian) strata of Tennessee. Taxocrinus strimplei n. sp. and Onychocrinus sp. A are reported from a single locality in the Bangor Limestone in Cumberland County, east-central Tennessee. Specimens of both species are characterized by having fewer numbers of brachials than any species yet referred to either genus. Both the evolutionary development of their brachial series and their stratigraphic position suggest that these species are at or near the end of lineages of these two genera.
