Al-though the adaptations arechiefly terrestrial, we tracecertain strong analogies ifnot actual relationships tothe Permo-Triassic reptilesof North America. While the drying poolsand lagoons of arid NorthAmerica were entombing thelife of the Permian andTriassic Epochs, there werebeing deposited in the Karooseries of South Africa some9,500 feet of strata consist-ing of shales and sandstones,chiefly of river flood-plainand delta origin, and rang-ing in time from the basal ^ > ^ t ITt ■^>.^ii^ -*\.
