The Triassic fossils are still more closely allied, more than a third of the species being identical.
It is further agreed that the Triassic strata were deposited after these.
Among his other contributions to the literature of palaeontology was his description of the Triassic reptile Telerpelon elginense.
From Prototheria to something like the Theromorpha at the bottom of the Triassic strata.
These are composed chiefly of Triassic beds, but Jurassic and Cretaceous beds take some share in their formation.

The earliest period of the Mesozoic Era, from about 245 to 208 million years ago. During the early part of the Triassic Period the supercontinent Pangaea was located along the equator; by the end of the Triassic it had started to split up. Land life diversified in the Triassic in response to the mass extinctions of the end of the Paleozoic. Conifers, cycads, marine reptiles, dinosaurs, and the earliest mammals first appeared.
