The rocks above the Permian ones are from the Triassic and date to between 248 million and 206 million years. Rocks of this age are found in the lower walls of Lanner 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".
