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
Mesangiospermae are fossil mesangiosperms from the Hauterivian stage of the Cretaceous period. Molecular clock comparisons of DNA sequences indicate that the mesangiosperms originated between 140 and 150 Mya (million years ago) near the beginning of the Cretaceous period. This was about 25 Ma (million years) after the origin of the angiosperms in the mid-Jurassic. By 135Mya, the mesangiosperms had radiated into 5 groups: Chloranthales, Magnoliids, Monocots, Ceratophyllales, and Eudicots. The radiation into 5 groups probably occurred in about 4 million years. Because the interval of this radiation (about 4 million years) is short in proportion to its age (about 145 million
