The affinities of the early cynodont reptile, Nanictosaurus [PDF]

open access: yes, 1990
This investigation into the anatomy of the four extant specimens of Nanictosaurus has revealed that there is one valid species, viz. N. kitchingi Broom 1936 which has two junior synonyms, viz. N. robustus Broom 1940 and N. rubidgei Broom 1940.

Modeling the jaw mechanics of Dimetrodon (Synapsida: Sphenacodontidae)

open access: yes, 2022
In this work, I investigate the biomechanics of a 295-million-year-old proto-mammal, Dimetrodon, using a series of models and experiments to recreate their jaw as accurately as possible. Using a combination of 2D images and computed tomography scans, virtual fossils were created in 3D.
