New Genus and Species from the Cretaceous of Lebanon Links the Thylacocephala To the Crustacea

Abstract

A continuing study of a collection of marine arthropods from the Upper Cretaceous of Sahel Alma in Lebanon has uncovered a new genus and species of the problematic arthropod group Thylacocephala. The apparent presence of two pairs of antennae constitutes the first available morphological evidence for a close relationship between this species and, by association, all thylacocephalans, and the Crustacea.
