Short summary
Forcipulatacea is one of the major clades of extant sea stars with 400 extant species described, but with fewer than 25 fossil species known. Thus, the identification of any new fossil representatives is significant. We reappraise Ophidiaster davidsoni from the Tithonian of Boulogne, France, which was assigned to another major extant group, and reassign it within a new forcipulatacean genus Psammaster gen. nov. A phylogenetic analysis does not place it within any existing forcipulatacean family.
