Abstract
SUMMARY: Inadunates dominate the Chadian crinoid fauna of Salthill Quarry, Clitheroe, Lancashire, despite the apparent prevalence of camerates. Well-preserved arms of a crinoid, which have swollen axillaries and an ornament of tubercles, are derived from a new taxon of inadunate crinoid. The arms are pinnulate and branching is heterotomous at the secundaxils (except in the A-ray, which does not divide at this level). Dissociated brachials and radials of this species are common.This publication has 4 references indexed in Scilit:
