Edited by Lyndsey on Thu, 10/03/2011 - 13:26

Catinaster calyculus Martini and Bramlette, 1963

Description: Curved rays extend beyond basket. (N.B. Peleo-Alampay and Wei, 1995, Peleo-Alampay et al., 1998, use basket shape as an alternative criterion for defining C. calyculus, but without markedly better biostratigraphic discrimination). The rays lengthen through the range of the species according to Martini (1981).
