  Abstract

    The present 3D Dataset contains the 3D models of three specimens of Spinosauridae: two Cristatusaurus lapparenti Taquet & Russell, 1998 (MNHN.F.GDF365 and MNHN.F.GDF366) and one Spinosaurus maroccanus Russell, 1996 (MNHN.F.SAM124). These specimens are analyzed and discussed in Pittet F. 2026. Neurovascular system and dental renewal in the rostrum of Spinosauridae: new descriptions and implications on non-olfactive snout sensitivity of dinosaurs, Geodiversitas.
