Late Mesozoic Paleoclimatology . 1. Figure 14.35: During the late Mesozoic, water covered a larger proportion of the earth's surface than today. Solar radiation effectively warmed the water and the heat was distributed pole-ward by the ocean currents, producing an overall warm climate with ice-free poles.Triassic Period (240 to 208 million years ago) At the beginning of the Mesozoic Era, the “supercontinent” began to break up. Deserts covered part of the interior, but shallow seas re-invaded the lowlands. Reptiles evolved rapidly, and two important new groups appeared. Therapsids (mammal-like reptiles) gave rise to true mammals by the end ...

mammal. Mammal - Evolution, Classification, Adaptations: Mammals were derived during the Triassic Period from therapsids.
