Researchers dated ash deposits from this hill, called a koppie in South Africa. The lower part of koppie Loskop exposes strata from before the end-Permian extinction (Palingkloof Member of the Balfour Formation), while the upper part contains layers deposited after the extinction (Katberg Formation).

This mural was originally made for a recent Royal Ontario Museum exhibit about a fossil ankylosaur named Zuul crurivastator. That fossil is found within a couple of meters stratigraphically/temporally of the site described in this paper. The last author on the study, David Evans, is the dinosaur curator at the Royal Ontario Museum and was also involved in the description of Zuul and design of that exhibit.
