Geocoma Cretaceous Brittlestar Fossils

Description: A rarely seen member of the Ophiuroidea, or Brittlestars, this is a pair of Geocoma libanotica. The generic name is derived from the location (Lebanon), an area better known for its fine preserved fish and Crustaceans. The sublithographic limestone also preserved incredible detail here as well. The genus is also known from the Jurassic deposits of Solnhofen, Germany where Geocoma carinata is often seen. These Brittlestars are over 50 million years younger, showing that the genus was quite long-lived.
