The Triassic reptile Palacrodon browni Broom, synonymy and a new specimen
(Bernard Price Institute for Palaeontological Research, 1999) Gow, Chris E
Palacrodon browni Broom 1906 (=Fremouwsaurus geludens Gow 1992) is a small enigmatic diapsid reptile from the Cynognathus Assemblage Zone of South Africa and Antarctica whose dentition is very similar to that of coeval procolophonids.
Preliminary report of dinosaur tracks in Qwa Qwa, South Africa
(Bernard Price Institute for Palaeontological Research, 1999) Gow, Chris E; Latimer, E M
We record the presence of tridactyl dinosaur tracks preserved on a siltstone surface in a watercourse in a north eastern Free State game park.
A captorhinid with multiple tooth rows from the Upper Permian of Zambia
(Bernard Price Institute for Palaeontological Research, 2000) Gow, Chris E
Captorhinids are some of the best known early amniotes. They range throughout the Permian and occur in North America, Europe, India and Africa. There are several small forms with single rows of marginal teeth, medium sized multiple-rowed forms typified by Captorhinus, and large forms most of which possess numerous rows of marginal teeth. As a group, captorhinids are extremely conservative in cranial morphology in most other respects. A small Late Permian, single rowed form has been recorded from the Madumabisa Mudstone of Zambia, equivalent in age to the Cistecephalus Assemblage Zone of the Karoo Basin of South Africa. This paper records a multiple-rowed form from these rocks similar in size to Captorhinus, but with distinctive dentition
A new procolophonid (Parareptilia) from the Lystrosaurus Assemblage Zone, Beaufort Group, South Africa
(Bernard Price Institute for Palaeontological Research, 2000) Gow, Chris E
This paper describes the skull of a new genus and species of procolophonid from the Lystrosaurus Assemblage Zone. It is strikingly different from its contemporaries, Procolophon trigoniceps and Owenetta rubidgei, but has a mosaic of characters of each.
A partial skeleton of the tritheledontid Pachygenelus (Therapsida: Cynodontia)
(Bernard Price Institute for Palaeontological Research, 2001) Gow, Chris E
Tritheledontids are advanced cynodonts that are considered the sister group of Mammalia. To date the postcranial skeleton has remained largely unknown, so that cladistic analyses are based on cranial characters only. This paper describes a specimen of the tritheledontid Pachygenelus which has most of the skull and vertebral column, a complete shoulder girdle, and most of the forelimb. The girdle and limb are closely comparable to those of Massetognathusand Eozostrodon, and unlike these elements in tritylodontids, which are more derived for fossorial specialisations.
New find of Diarthrognathus (Therapsida: Cynodontia) after seventy years
(Bernard Price Institute for Palaeontological Research, 1994) Gow, Chris E
Diarthrognathus is arguably South Africa's most famous therapsid fossil. Since its discovery seventy years ago no new material had come to light until now. This paper records the recovery, from the Elliot Formation of South Africa, of a partial left lower dentary with most of its dentition preserved.
An enigmatic new reptile from the Lower Triassic Fremouw Formation of Antarctica
(Bernard Price Institute for Palaeontological Research, 1992) Gow, Chris E
The partial skull of a new reptile from the Lower Triassic of Antarctica is described: It has a distinctive procolophon-like dentition, but other features suggest it is a diapsid. The name Fremouwsaurus geludens is proposed for the new animal. It is not possible to place the new form in any known higher taxon, so it is necessary to establish a new Family Fremouwsauridae to receive it.
Skulls of the prosauropod dinosaur Massospondylus carinatus Owen in the collections of the Bernard Price Institute for Palaeontological Research
(Bernard Price Institute for Palaeontological Research, 1990) Gow, Chris E; Kitching, James W; Raath, Michael A
Description of the skull of Massospondylus (Prosauropoda, Anchisauridae) is largely unnecessary since excellent descriptions now exist of Plateosaurus (Galton 1984, 1985a) which, though larger and of slightly different proportions, is anatomically almost identical. This paper presents comprehensive illustrations of the Massospondylus skulls in the Bernard Price Institute collections and discusses only those aspects of this material in which Massospondylus differs from Plateosaurus, or which further add to our knowledge of the prosauropod skull. It is shown that Attridge et al. ( 1985) give spurious reasons for considering the recently discovered Massospondylus skull from Arizona to differ from the southern African taxon, and that the suggestion of Crompton and Attridge ( 1986) that this animal may have had a horny beak on the tip of the lower jaw is unnecessary and improbable.
Morphology and growth of the Massospondylus braincase (Dinosauria Prosauropoda)
(Bernard Price Institute for Palaeontological Research, 1990) Gow, Chris E
The almost complete disarticulated braincase of a young Massospondylus, and the partial braincase of a very large individual in which the laterosphenoid bones are preserved, are described.
