Sister taxa: C. calyculus, C. coalitus, C. glenos, C. mexicanus, C. sp.,

Taxonomy:

Citation: Catinaster calyculus Martini and Bramlette, 1963
Rank: Species

Farinacci & Howe catalog pages: Catinaster calyculus * , Catinaster calyculus rectus * , Catinaster coalitus extensus *


Morphology remarks:

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).
