Abstract
A new cyrtocrinid crinoid coming from Bajocian sediments of the Central Italy is described and named Fischericrinus sandrae n.gen. n.sp.: moreover Phyllocrinus belbekensis Arendt, 1974 is point out and discussed from the systematics point of view. It is the first time that cyrtocrinids surely Bajocian in age coming from the Italy are described and these findings let us hypothesize an origin of cyrtocrinid crinoids somewhat different by previous works.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
