Abstract
A new rudist bivalve, Curtocaprina clabaughikinsorum gen. et sp. nov. is described from the Middle Albian of Texas. This species shows characters that relate it both to the Caprinuloideidae and to the Ichthyosarcolitidae. It shows a small posterior tooth separated from the large anterior tooth by a central socket as well as an additional toothlet (called here the ichthyosarcolitid toothlet) and two plate-like myophores in the left valve. The anterior tooth and ichthyosarcolitid toothlet fit into slots in the body chamber of the right valve, whereas the two wall-like myophores face directly onto the inner surface of the body cavity in the right valve. Curtocaprina is a primitive member of the Ichthyosarcolitidae and suggests that the family originated before the mid Albian most likely from an as yet unknown primitive form of Caprinuloideidae....
