Terminasteridae

Terminasteridae is a family of fossil starfish which lived from the Jurassic to Cretaceous periods. It was erected in 2011 as a monotypic group to contain only the type genus Terminaster (which it is named after).^[1] A second genus, Alkaidia, was originally described as a member of the extant family Benthopectinidae, but was transferred to Terminasteridae in 2020.^[2]
