Notes on some fossil pockets and bone beds in the Cynognathus- zone in the Burghersdorp and Lady Frere districts

Most palaeontological field workers are familiar with the blue to green shales and maroon to red mudstones, as well as the fine-grained greenish-blue sandstones, of the Cynognathus-zone, all these colours contributing to its general patchy appearance. Heights within the zone can unfortunately not be determined reliably with the assistance of particular colour sequences, but a conspicuous and persistent sandstone horizon marks the middle level of the zone. Our knowledge of the manner in which fossils occur both above and below this horizon is not satisfactory.
