The Kalahari Deposits is an Late Cretaceous (Campanian to Maastrichtian)[1][2] geologic formation in South Africa. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.[3] The depositional environment is described as a crater lake where poorly lithified, concretionary conglomerate and volcaniclastic, intraclastic, calcareous mudstone were deposited under quiet subaqueous conditions, probably a "crater-fill succession above an olivine-melilitie intrusion".[4]
