Anterior view of distal neotragine humerus L40787. H. Proximal articular surface of neotragine radius L40088 with part of its back edge taken from L40021. a = medial malleolus, b = fibula facets, c = main facet for naviculocuboid, d = main facet for ectocuneiform. For the first four characters two or all three of the humeri are unlike alcelaphines, but for the last three characters L30392 and L32629 resemble them. None of the characters is definitely unlike later Reduncini, and although the second and third could be held to resemble Tragelaphini, the last three do not agree very well with that tribe. Most characters of the proximal radii are unlike Alcelaphini: the lateral facet is broader and longer (not in L31937C), not pointed anteriorly, and its posterior edge is not stepped forward from the level of the back edge of the medial facet. The lateral tubercle is small and low. The indent in the back edge of the medial facet is less deep than in Alcelaphini, and the anteromedial part of that facet is more extensive in L30392 (but not in L31937C or L24932) than in Alcelaphini. It is interesting that there is no medial rim on the medial facet —unlike later Reduncini or Tragelaphini. Comparisons The Langebaanweg fossils agree well with a frontlet and three horn-core pieces from Sahabi, now in Rome. The Sahabi h
