Once upon a time, this beautiful float-bearing camerate crinoid had been very
abundant in uppermost Silurian and lowermost Devonian seas on the territory of
the Barrandian area, Czech Republic. It does not occur in the rocks of North
America as suggested by Springer (1917).
The American species is a different
one (it differs markedly in the number of SBrr in adults) but is not yet
revised!
The revision of the Bohemian species was given by Prokop and Petr
(1986). Kacha and Petr (1996) have pointed out that there is an interesting
possibility of the existence of Mullerian mimics in the uppermost Silurian
float-bearing community of coexisting genera Scyphocrinites Zenker and
Carolicrinus Waagen and Jahn (see also the picture of Carolicrinus).
