Biological Reviews, Volume 96, Issue 5, Page 2229-2257, October 2021., 2021 ABSTRACT The morphology of the temporal region in the tetrapod skull traditionally has been a widely discussed feature of vertebrate anatomy. The evolution of different temporal openings in Amniota (mammals, birds, and reptiles), Lissamphibia (frogs, salamanders, and caecilians), and several extinct tetrapod groups has sparked debates on the ...

Evolution and identity of synapsid carpal bones [PDF]
, 2020 To date there is little information on carpal bone homology in late Palaeozoic and Mesozoic Synapsida. Crucial to the understanding of homology in synapsid carpal elements is the fact that different nomenclatures are used for the carpals of non ...

The palatal dentition of tetrapods and its functional significance [PDF]
, 2017 The presence of a palatal dentition is generally considered to be the primitive condition in amniotes, with each major lineage showing a tendency toward reduction. This study highlights the variation in palatal tooth arrangements and reveals clear trends

A Summary of the Gorgonopsia and its Members [PDF]
, 2021 Gorgonopsids were a group of Therapsids that lived from the mid to late Permian. They were the dominant predators in their ecosystem. Their remains are found primarily in the South African Karoo Basin, and parts of Eastern Russia.

Morphological convergence obscures functional diversity in sabre-toothed carnivores [PDF]
, 2020 Copyright de los autoresThe acquisition of elongated, sabre-like canines in multiple vertebrate cladesduring the last 265 Myr represents a remarkable example for convergentevolution.

, 2016 Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical transformations throughout the past 270Ma, eventually leading to the evolution of the mammalian ...

THE MODE OF LIFE OF GORGONOPSIANS [PDF]
, 1973 The gorgonopsians as typically developed were undoubtedly the dominant land carnivores of the Upper Permian and have been compared with the sabre-tooth cats of the Tertiary (Parrington, 1955, p. 7 and Kemp, 1969b, p. 321).

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
