The Umfolozia arthropod trackways in the Permian Dwyka and Ecca Groups of South Africa

Anderson, Ann M. (Bernard Price Institute for Palaeontological Research, 1977)

Umfolozia trackways are widespread in the glacial Dwyka and in the overlying non-glacial Ecca deposits. Populations from ten localities have been numerically analysed. A consistent, significant difference is found between ...
Permo-triassic "lizards" from the Karoo System. Part II: A gliding reptile from the upper Permian of Madagascar

Carroll, Robert L. (Bernard Price Institute for Palaeontological Research, 1977)

Daedalosaurus madagascariensis, gen. et sp. nov. from the Upper Permian of Madagascar is a small reptile in which the trunk ribs are greatly elongated to support a gliding "membrane" similar to those in the Upper Triassic ...
Podozamites and associated cones and scales from the upper Triassic Molteno Formation, Karoo Basin, South Africa

Anderson, Heidi M. (Bernard Price Institute for Palaeontological Research, 1977)

The leaves Podozamites elongatus (Morris) Feistmantel from 24 localities, the cones Telemachus elongatus gen. et sp. nov. from nine localities and the scales Dordrechtites elongatus gen. et sp. nov. from seven localities ...
The biostratigraphy of the Permian and the Triassic. Part 5: A review of the classification and distribution of Permo-Triassic tetrapods

Unknown author (Bernard Price Institute for Palaeontological Research, 1977)

A tabulated synthesis of the classification, with geographic and stratigraphic ranges, of the Permo-Triassic tetrapod genera (amphibians, reptiles and mammals) is presented. 657 named genera placed in 161 families are ...
Three capitosaurs from the Triassic of South Africa: Parotosuchus africanus (Broom 1909); Kestrosaurus dreyeri Haughton 1925, and Parotosuchus dirus sp. Nov.

Chernin, Sharon (Bernard Price Institute for Palaeontological Research, 1978)

Two members of the family Capitosauridae are redescribed after further preparation, namely Paratosuchus africanus (Broom 1909) and Kestrasaurus dreyeri Haughton, 1925. New material consisting of a fragmental, lower jaw ...
Palaeoenvironmental models in the Eastern Karoo Basin

Hobday, D. K. (Bernard Price Institute for Palaeontological Research, 1978)

Palaeoenvironmental models are based on a three-dimensional conception of sedimentary rock units and their internal geometry. These models are process-oriented and are interpreted by comparison of their attributes with ...
Allometric growth in the Diademodontinae (Reptilia; Therapsida); a preliminary report

Grine, F. E.; Hahn, B. D. (Bernard Price Institute for Palaeontological Research, 1978)

The hypothesis that many, if not all, of the South African and Zambian specimens, which have been regarded as different diademodontine genera and species, actually consitute a taxonomically homogeneous, ontogenetic growth ...
Feeding adaptations in Triassic Dicynodonts

Cruickshank, A. R. I. (Bernard Price Institute for Palaeontological Research, 1978)

The Dicynodontia declined markedly at the close of the Permian, entered the Triassic with very few species and had a final burst of evolutionary success in the Middle Triassic, before being overcome by archosaurian ...
Aspects of palynology in Rhodesia

Falcon, Rosemary M. S. (Bernard Price Institute for Palaeontological Research, 1978)

This paper is based on a Doctoral Thesis presented to the University of the Witwatersrand, which in whole or part will be published elsewhere at greater length. The essence of the research is presented in three text ...
Atmospheric carbon dioxide/oxygen imbalance in the late Cretaceous, hatching of eggs and the extinction of biota

Oelofsen, B. W. (Bernard Price Institute for Palaeontological Research, 1978)

A new theory explains why dinosaurs, pterosaurs and large avian species like Hesperornis became extinct at the end of the Cretaceous while mammals, smaller Cretaceous birds, crocodiles, chelonians and saurians survived ...
The stratigraphic distribution and occurrence of South African fossil Amphibia in the Beaufort beds

Kitching, J. W. (Bernard Price Institute for Palaeontological Research, 1978)

A short account is given of the distribution and occurrence of fossil amphibians from the Beaufort succession, based on analyses of specimens in various South African and overseas institutions. Their occurrence is based ...
Trackways in the Stormberg

van Dijk, D. E. (Bernard Price Institute for Palaeontological Research, 1978)

Vertebrate trackways in the lower groups of the Karoo Supergroup are mainly pre- Beaufort fish trails, although some tetrapod trackways are known (Griffiths, 1963, p. 292; plate I; specimens in the South African Museum). ...
Notes on a specimen of Diademodon previously referred to Cyclogomphodon

Grine, F. E. (Bernard Price Institute for Palaeontological Research, 1978)

The anterior portion of the cranium of a medium-sized cynodont is described. The specimen was previously described briefly by Brink and Kitching (1953 ), who assigned it to the genus Cyclogomphodon Broom, and it was upon ...
A new bauriamorph from the Omingonde Formation (Middle Triassic) of South West Africa

Keyser, A. W. (Bernard Price Institute for Palaeontological Research, 1978)

A new genus and species of bauriamorph therapsid from the Anisian Omingonde Formation (Middle Triassic) of South West Africa is described as Herpetogale marsupialis gen. et sp. nov. This new form is chronologically the ...
The advent of herbivory in certain reptilian lineages during the Triassic

Gow, C. E. (Bernard Price Institute for Palaeontological Research, 1978)

The dentitions of several presumed herbivorous Triassic reptiles are described and discussed. Some changes in dentitions with growth suggest that juveniles were insectivorous. The appearance of these forms may have been ...
