Note 11 — Introduction.

On the evidence of the very close affinities between the plants and animals in Africa and India at a very remote period, Mr. R. D. Oldham concludes that there was once a continuous stretch of dry land connecting South Africa and India. “In some deposits,” he writes,11 “found resting upon the Karoo beds on the coast of Natal, 22 out of 35 species of Mollusca and Echinodermata collected and specifically identified, are identical with forms found in the cretaceous beds of Southern India, the majority being Trichinopoly species. From the cretaceous rocks of Madagascar, six species of cretaceous fossils were examined by Mr. R. B. Newton in 1899, of which three are also found in the Ariyalur group (Southern India). The South African beds are clearly coast or shallow water deposits, like those of India. The great similarity of forms certainly suggests continuity of coast line between the two regions, and thus supports the view that the land connection between South Africa and India, already shown to have existed in both the lower and upper Gondwána periods, was continued into cretaceous times.”
