Abstract/NotesFive Jurassic through Oligocene sea stars are described; all are assignable to modern genera and two (Tethyaster jurassicus; Mediaster hayi) represent new species. Tethyaster and Pseudarchaster are morphologically similar but represent separate orders; occurrence of both in Jurassic sediments suggests close common ancestry. Many post-Paleozoic sea stars appear enduring, perhaps because of broad ecological tolerances and construction; the fossils described here probably are not unique as asteroid living fossils.
