The present dataset contains 3D models used for illustration purposes in Schultz, J. A., Weaver, L. N., Jäger, K. R. K. & Grossnickle, D. M., 2026. Reexamining the evolutionary history of the mammalian medial pterygoid muscle. Evolution. The dataset includes 3D models based on micro-computed tomography (µCT) data of the postdentary area of the morganucodontan Morganucodon, the docodontan Docodon, the eutriconodontan Priacodon and the cladotherian Dryolestes. In addition, the dataset includes manually reconstructed schematic 3D models of the middle ear bones for the morganucodontan Morganucodon, the docodontan Docodon, the eutriconodontan Priacodon and schematic middle ear bones and a virtually rendered juvenile lower jaw of a juvenile monotreme Ornithorhynchus (based on illustrations of Zeller [1989]).
