Abstract

Almucidaris durhami is a new genus and species of cidaroid echinoid from the Maastrichtian (Late Cretaceous) of Seymour Island, Antarctic Peninsula. The species is unique in that the genital plates of the female are expanded and hollowed to form marsupia. The indicidence of brooding in invertebrates, including echinoderms, increases with latitude and apparent stress; stressful conditions might have contributed to the evolution of A. durhami. -Authors
