Abstract:
A general locomotor model for derived dicynodont anomodonts is proposed on the basis of a functional analysis of the pelvic girdle and entire hind limb of the medium-sized Middle Triassic dicynodont Tetragonias njalilus. The joint mobility of the hind limb is examined, and a hind limb step cycle is reconstructed. The data provided in this case study indicate that Tetragonias adopted a highly adducted (upright) hind limb posture during stance and most of its stride. Nevertheless, lateral undulation of the vertebral column must also have contributed to the locomotion of dicynodonts. Character op

Abstract:
AbstractConstraint is a universal feature of morphological evolution. The vertebral column of synapsids (mammals and their close relatives) is a classic example of this phenotypic restriction, with greatly reduced variation in the number of vertebrae compared with the sauropsid lineage. Synapsids generally possess only three sacral vertebrae, which articulate with the ilium and play a key role in locomotion. Dicynodont anomodonts are the exception to this rule, possessing seven or more sacral vertebrae while reaching a range of body sizes rivaled among synapsids only by therian mammals. Here w

The dicynodont genus Lystrosaurus, a relative of the Kannemeyerids, is one of few terrestrial vertebrate genera which can be found on both sides of the Permian-Triassic (P-T) boundary (Botha and Smith, 2006); indeed, a single species, Lystrosaurus curvatus, is known from both periods. In the Permian, Lystrosaurus was of average abundance relative to other genera. Shortly following the P-T extinction, it drastically increased in abundance until it dominated the faunas it was present in (Botha and Smith, 2006). To date, Lystrosaurus fossils have been found in South Africa, India, Antarctica, Chi

Abstract:
Dicynodonts were a diverse group of herbivorous therapsids from the PermoTriassic. Differences in cranial morphology among the Dicynodontia have been correlated with changes in masticatory function, and hence, dietary preference. Cranial specialisations of Lystrosaurus were hypothesised to have increased the efficiency of its masticatory system relative to generalised Permian dicynodonts. To test this hypothesis, the cranial function of Lystrosaurus is compared with the generalised dicynodont Oudenodon using finite element analysis (FEA), a computational analysis of structural form, in combina

The genus Kannemeyeria is one of the most important and distinctive taxa of the Triassic dicynodonts.

An understanding of this genus forms an integral part of the biozonation of the Beaufort Group, and is pivotal in influencing the interpretation of the evolution, physiology and phylogenetic relationships of the Triassic dicynodonts.

Abstract:
‘The origin of mammals’ considers the evolutionary history of mammals using the fossil record to chart their developmental progress. It looks at a group of ‘pre-mammals’, the Synapsids—mammal-like reptiles—including pelycosaurs from 320 mya in the Upper Carboniferous. Then came the therapsids from c.260 mya in the Middle Permian, when the world was increasingly arid. Then 250 mya a mass extinction event wiped out over 90 per cent of animals and plants. Miraculously, a few therapsids survived including the burrowing dicynodont called Lystrosaurus and cynodonts that evolved throughout the Triassic and gave rise to mammals. The earliest mammal was a mouse-sized animal called Morganucodon from 200 mya.
