Early cynodonts have many of the skeletal characteristics of mammals. The teeth were fully differentiated and the braincase bulged at the back of the head. Outside of some crown-group mammals (notably the therians), all cynodonts probably laid eggs.

Cynodont, any of a group of mammal-like reptiles of the order Therapsida that existed from the late Permian to the early Cretaceous Period. Cynodont skulls have many features that anticipate those found in mammals, and fossil evidence suggests that mammals evolved from cynodonts early in the Jurassic Period.

Apr 12, 2023 · Contrary to historical belief, skull strength during the cynodont–mammalian transition did not increase with the reorganisation of the cranial bones and simplified jaw joint.

Cast of the skull of Kayentatherium. [1][2] It had a skull about 10cm (4 inches) in length. The Cynodonts are a sub-order of the Therapsida. Cynodonts, one of the most diverse groups of therapsids, are named after their dog-like teeth. The taxon is a clade which includes modern mammals and their extinct close relatives, the Mammaliaformes.

The cranial anatomy of the early non‐mammalian cynodont Galesaurus planiceps from the South African Karoo Basin is redescribed on the basis of a computed tomographic reconstruction of the skull. Previously, little was known about internal skull ...

The cynodonts are a very well-known and intensely studied volume of phylospace. In particular, a series of interdependent changes in the cynodont head -- mostly soft tissue changes -- has been the focus of much science and not a little inspired speculation.

An acetic acid prepared skull of the Upper Permian Karroo cynodont Procynosuchus delaharpeae Broom is described and an attempt is made to interpret its anatomy in functional terms. The dentition is adapted for an insectivorous habit with an incipient form of tooth occlusion between specific upper and lower postcanines.

An acetic acid prepared skull of the Upper Permian Karroo cynodont Procynosuchus delaharpeae Broom is described and an attempt is made to interpret its anatomy in functional terms.

The general anatomy of the adult Thrinaxodon skull has been elucidated by Parrington (1946b), and Olson 1944) has discussed the ear region, but this specimen shows some additional points of interest. FORAMINA OF THE SNOUT

Aug 21, 2009 · The author examines the structure of the skull in the Dicynodontia, and discusses the interpretations of its elements and affinities given by Sir Richard Owen, Professor Huxley, and Professor...
