Paleontologists have discovered the remains of the animal in South-West Tanzania. According to their estimates, P. rukwaensis was the size of a lynx. Biogeographic and phylogenetic analysis gave the opportunity to learn more about the transition from early African predators to the modern ecosystem.

After the mass extinction of the dinosaurs hyaenodonts were the main predators in Africa, while from 23 to 25 million years ago, the continent has not got other predatory animals.
