Abstract

Specimens collected from the Lower Cretaceous (Albian) Hudspeth Formation, Oregon, are referable to Anoplocarcinus hudspethi new genus, new species. The new taxon is supported by phylogenetic analysis as well as comparison to type and referred material within Orithopsidae of Raninoida. Albian decapods are rare from the Pacific Coast of North America; this is only the third decapod species reported from the region. Orithopsidae is already well-known from Early Cretaceous occurrences worldwide, and although the new taxon does not extend the geologic range for the family, it expands the biogeographic distribution and morphological diversity among Early Cretaceous orithopsids.
