- ItemNew species of Parmularius hopwood and Damaliscus sclater and Thomas (Alcelaphini, Bovidae, Mammalia) from Makapansgat, and comments on faunal chronological correlation(Bernard Price Institute for Palaeontological Research, 1977) Vrba, Elizabeth S.Two new species of Alcelaphini, based on fossils from the Makapansgat Limeworks, are described. One is an early member species of the extinct genus Parmularius Hopwood. The present description is the first record of a Parmularius from any southern African fossil site. The other new species belongs to Damaliscus Sclater and Thomas, and is closely related to the extinct Damaliscus niro (Hopwood). The phylogenetic relationships of the new species to other extant and extinct alcelaphines are discussed. Comparison with fossils of the same, and/or related, species elsewhere in Africa gives rise to comments on faunal chronological correlation.
- ItemTechnological note: a cheap stereophotograph apparatus(Bernard Price Institute for Palaeontological Research, 1977) Thackwray, H. O.The need for a gadget for taking stereo pairs of photographs has been evident for some time. What was needed was a cheap, pocket-sized gadget that would fit all makes of cameras, could be used for close-up photos, large immovable objects and even landscapes. It had to be simple and easy to operate.
- ItemFossil insect wings from the early Permian White Band formation, South Africa(Bernard Price Institute for Palaeontological Research, 1977) McLachlan, Ian R Anderson, Anne MFossil insect remains are reported for the first time from the Lower Karroo White Band in South Africa. The wings of two individuals have been recovered from separate localities 140 km apart in the southern Cape fold-belt. They unfortunately supply little useful information on the depositional environment of the White Band as they were probably transported some distance to their final site of preservation.
- ItemAn investigation of the lower Permian middle Ecca ammonite locality at Alleta, Natal(Bernard Price Institute for Palaeontological Research, 1977) McLachlan, I. R.The problematic ammonite Paraceltites bowdeni Teichert & Rilett has been recorded only from the Alleta iron-ore mine near Dundee in Natal. It is unique in the Early Permian Ecca Series as it suggests a normal salinity for the depositional environment of sediments that have yielded no other clearly marine fossils. An investigation of the matrix of the specimen slabs, however, yields information which is incompatible with equivalent data from the Alleta mine and the Ecca sediments in general. The matrix contains the distinctive pollen Classopollis which is not known from elsewhere in the world in deposits older than Late Triassic. Comparative tests of the degree of thermal diagenesis of the contained organic material suggests that the ammonite specimens have not been subjected to the same degree of alteration as the sediments at the Alleta mine. Results of other tests have not been definitive but do not contradict the suggestion that the ammonites were mistakenly accredited to the A1leta mine. It is concluded that the ammonites derived originally from sediments of Late Triassic to Early Jurassic age at an unknown locality outside of South Africa.
