Eryma jungostrix n. sp. (Decapoda; erymidae) from the redwater shale member of the stump formation (Jurassic; Oxfordian) of Utah

Abstract

A single, well-preserved fossil specimen of a large macruran decapod from the Jurassic Redwater Shale Member of the Stump Formation in northeastern Utah forms the basis for description of a new species of Eryma von Meyer, 1840. The discovery documents only the third species of the genus, and one of very few decapods, to have been described from Jurassic rocks in North America.
