First record of Triassic Rhynchosauria (Reptilia: Diapsida) from the Lower Zambezi Valley, Zimbabwe
(Bernard Price Institute for Palaeontological Research, 1992) Raath, Michael A; Oesterlen, P M; Kitching, James W
True rhynchosaurids are described from Zimbabwe for the first time. The fossils occur as partially associated skeletons and scattered isolates in upward-fining, micaceous fluvial sandstones of the Pebbly Arkose Formation (late Triassic) in the Western Cabora Bassa Basin, Lower Zambezi Valley. On the grounds that the dentary of the Zimbabwean form possesses a row of small, conical lingual teeth in addition to a palisade row of penicillate teeth on the occlusal surface, it is concluded that the taxon present is Hyperodapedon sp., and that it is closely related to a rhynchosaurid described from Tanzania. One bone identified as a prosauropod dinosaurian femur was found associated with the Zimbabwean rhynchosaurids. The late Triassic age suggested by the presence of advanced rhynchosaurids is supported by the occurrence of the typical Triassic fossil plant genus Dicroidium, and by the general stratigraphy of the beds which contain the fossils (i.e. the fossil-bearing beds are underlain by beds of mid-Triassic age or younger, and are overlain by beds of latest Triassic or early Jurassic age)
Dinosaur tracks in Triassic Molteno sediments: the earliest evidence of dinosaurs in South Africa?
(Bernard Price Institute for Palaeontological Research, 1990) Raath, Michael A; Kitching, James W; Shone, Russell W; Rossouw, G J
A fossil tracksite containing well-preserved tridactyl footprints of bipedal theropod dinosaurs is reported from fluvial overbank deposits of Molteno age (Stormberg Group: Triassic) in the northeastern Cape Province, South Africa. They occur stratigraphically below the mudrocks of the Elliot Formation, in which dinosaur remains are comparatively common, and are taken to represent the earliest evidence for dinosaurs in South Africa. They also represent the earliest unequivocal evidence of tetrapods in Molteno deposits.
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.
