is a genus of gorgonopsid
that lived in Africa during the mid
Triassic. Njalila is not known by many fossils,
but we can observe
that the genus had relatively short jaws but also narrow skull
proportions. It is quite probable that Njalila
was a niche predator,
perhaps mostly hunting smaller animals.
Living in the early part of what is known as the Mid Triassic, Njalila was one of the last gorgonopsids genera to exist, with most others appearing only in the Permian. This is mostly because the end of the Permian is marked by the largest extinction event that we know to ever affect the planet wiping out most of the established animal life. As the Triassic went on, larger archosaurs became the top predators, until eventually they themselves were replaced by the early Dinosaurs.
