Entry/Object ID

LN2009.3.31

Description

A decapod identified in the original catalog as a "shrimp." It is also identified as the genus Astacus, but Astacus is the European crawfish. I am dubious of this identification. Especially since it was also called a "Shrimp," and the Hornbrook Formation is marine, not freshwater. Another possibility is that it could be Hoploparia, a marine lobster from the Cretaceous. This would fit with the specimen being from the Hornbrook Formation. Common Name: "Shrimp" Age: unknown (probably late Cretaceous) Formation: unknown (probably Hornbrook) Location: Siskiyou Mountains
