A varvite ichnocoenosis from the Dwyka Series of Natal

Arthropod trails and resting impressions are described from an horizon in the Dwyka Series of northern Natal. The sediments have been deposited in freshwater periglacial lakes and are of late Carboniferous or early Permian age. All the trails and resting impressions appear to have been made by crustacean arthropods, and it is suggested that syncarids or peracarids were probably responsible. Numerous fish traces are also present in this ichnocoenosis but these are still being studied by several workers and are not described below. The trace fossils described herein are Umfolozia sinuosa gen. et sp. nov., Diplichnites govenderi sp. nov., Diplichnites sp., Protichnites sp. A, Protichnites sp. B, Gyrochorte sp., Isopodichnus sp., Kingella natalensis gen. et sp. nov., and Gluckstadtella cooperi gen. et sp. nov.
