Abstract
The Cretaceous asteroid Arthraster is referred to the living family Chaetasteridae on the basis of similarities in ossicular arrangement in the abactinal disc and arms. Chaetasterina, previously identified as a chaetasterid, is transferred to the family Asterinidae, subfamily Hyalothricinae, and constitutes the first fossil record of the subfamily.
