Permian and Triassic Dicynodont (Therapsida: Anomodontia) Faunas of the Luangwa Basin, Zambia: Taxonomic Update and Implications for Dicynodont Biogeography and Biostratigraphy

open access: yes, 2013
Dicynodont fossils were first collected in the Luangwa Basin, Zambia, in the 1920s, but limited detailed study and taxonomic uncertainty have obscured their biostratigraphic utility and their implications for topics such as dicynodont biogeography and the effects of the end-Permian extinction.

Incorporating continuous characters in joint estimation of dicynodont phylogeny

open access: yesSystematic Biology
Abstract Continuous characters have received comparatively little attention in Bayesian phylogenetic estimation. This is predominantly because they cannot be modeled by a standard phylogenetic Q-matrix approach due to their non-discrete nature.

A RE-EVALUATION OF THE GENUS TROPIDOSTOMA SEELEY [PDF]

open access: yes, 1973
The type specimens of Cteniosaurus platyceps Broom, Dicynodon acutirostris Broom, and Dicynodon validus Broom were re-examined and were found to be very similar in a number of features rarely encountered in other Anomodontia.

The taxonomic status of Parathrinaxodon proops (Therapsida: Cynodontia), with comments on the morphology of the palate in basal cynodonts [PDF]

open access: yes, 2005
The holotype and only specimen of Parathrinaxodon proops, a cynodont from the Upper Permian Kawinga Formation, Tanzania, is redescribed. Upper postcanines from the middle of the tooth row are ovoid in outline, presenting a large main cusp and tiny ...
