Une nouvelle perspective dans l'étude des crinoïdes (Crinoidea, Echinodermata) : Un exemple du Jurassique inférieur du Monténégro

Abstract

Lower Jurassic (Hettangian-Pliensbachian) shallow-marine ooidal limestones of southern Montenegro contain a large number of isocrinid ossicles. They are assigned to the following taxa: Isocrinus psilonoti (Quenstedt), Isocrinus sp., and Pentacrinites cf. fossilis Blumenbach. The echinoderm assemblage also yields cyrtocrinid ossicles (Cotylederma sp., Cyrtocrinina indet.) and echinoid spines (only spotted in thin sections); however, these elements are rare. Given the fact that the recorded assemblage comes from a single locality, there is a growing need for further research that will require intense sampling to compile and complete the faunal list of crinoids and other echinoderm taxa.
