Abstract

Trilobites from the Soom Shale, Cedarberg Formation, of the Table Mountain Group, South Africa, have been identified as Mucronaspis olini Temple, indicating a latest Ordovician (Rawtheyan–Hirnantian) age. This new data is taken as an opportunity to present new records of some non age-diagnostic brachiopods and molluscs from the area, and also to review the substantial shelly fauna from the overlying Disa Member of the Cedarberg Formation. It is concluded that that fauna is of Hirnantian age and not early Llandovery as stated by some previous authors.
