The Clarens Formation is a lower Jurassic stratigraphic unit, forming the uppermost part of the Stormberg Group of the Karoo Supergroup in south-central Africa. It is well known for its fossil fauna, particularly in the Tuli Basin of the KwaZulu-Natal region of South Africa.
This formation represents the last record of sedimentary deposition of the Karoo Supergroup (although the upper part of the Clarens Formation and the lower part of the Drakensberg Formation appear to interleave). The majority of the sediments are fine-grained aeolian sand (either massive loess or large-scale cross-bedded dunes), with occasional playa lake, sheet flood and short-lived river deposits in places. The sand is generally well-sorted and numerous large-scale cross-bedded dunes are visible. Palaeowind directions are to the south-east.
