Two new genera and species of well-preserved fossil holothurians are described from the Lower Cretaceous (Albian) of Tepexi de Rodriguez, Puebla, central Mexico. Parapsolus tlayuensis is a psolid, and Paleopentacta alencasterae is a cucumariid. Paleopentacta alencasterae is the first complete holothurian fossil known to have two types of body wall ossicles preserved. The presence of the families Psolidae and Cucumariidae suggests that the local habitat was a hard substrate. The two holothurian species described here are interpreted as shallow water-suspension feeding species.
