Cretaceous Starfish Fossils Death AssemblageDescription: This plate displays a fine starfish death assemblage found in the Early Cretaceous deposits of Taba, Morocco. Most starfish offered come from the older Ordovician deposits of Morocco, and are primarily Ophiuroids, or brittlestars. Intact starfish specimens are quite uncommon in the fossil record. These specimens Asteroideaare members of the Asteroidea, or True Starfish. Unlike the brittlestars, true starfish have no demarcation between the arms and the ventral body, and move by means of tube feet rather than by the sinuous movements of the arms. The starfish are quite 3-D in appearance making for a dramatic display piece. Coming from a location only discovered in the last six years, it shows features much like those of modern-day members of the taxon. The horizon in which it was found is thought to have been a shallow water environment. They were most likely buried quickly, allowing them to be preserved nearly intact. See my other offerings for a single starfish fossil specimen.
