Makuleke Gorge and in these can be found fragments of bone and probably wood representing both holdovers from the Permian–Triassic extinction event like glossopetrids (a type of tree) and dicynodonts (a form of mammal-like reptile), and new forms that would dominate the Mesozoic, including modern conifers, cycads and of course dinosaurs, such as "Euskelosaurus". Most of the sandstones in the Pafuri region however probably represent the great age of dinosaurs – the Jurassic and Cretaceous Periods. During the early parts of the Jurassic, which lasted from approximately 210 million years ago until about 144 million years ago, the area was almost
Scleractinia on which to base a hypothesis about the origin of the scleractinians; plenty is known about modern species but very little about fossil specimens, which first appeared in the record in the Middle Triassic (). It was not until 25 million years later that they became important reef builders, their success perhaps a result of teaming up with symbotic algae. Nine of the sub-orders were in existence by the end of the Triassic and three more had appeared by the Jurassic (200 million years ago), with a further suborder appearing in the Middle Cretaceous (100 million years ago). Some may
