This contribution contains the 3D models of the paratympanic sinus system, the endocast and the neurovascular bony canal of the maxilla, premaxilla and the jugal of Leidyosuchus canadensis and Stangerochampsa mccabei described and figured in the following publication: G. Donzé, G. Perrichon, P. Vincent, JE. Martin, 2026. Comparative endocranial traits in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada. Journal of Anatomy.
