Sea Star Platastenras: Ossicle Morphology and Taxonomic Position

D. Bryan Blake 1

1 Department of Geology, University of Illinois at Urbana-Champaign, Urbana 61801

The modern sea star Platasterias latiradiata, on the basis of ossicle morphology, is removed from the fossil subclass Somasteroidea and assigned to the genus Luidia of the living subclass Asteroidea. A somasteroid assignment of this species should not be used in inferences concerning evolution and morphology of primitive echinoderms.
