Support has been given to the theory by the discovery of similar rock formations and fossil animals and plants in the two continents...
Like birds, mammals are revealed in the fossil records as descendants of reptiles. As long as 200,000,000 years ago some clumsy reptiles like Cynognathus ("Dog-Jaw") were already showing mammalian quirks around the mouth. By 100,000,000 years ago a few small creatures had probably crossed the mammalian line. Waiting for the gaudy Age of Reptiles to ring down its curtain, the little mammals had promising new equipment-hair for warmth, hot blood for cold weather, milk to feed their young on the move. Their brains grew bigger. When the mighty lizards died out, they were ready...
...speaking of the fossil exhibits at Agassiz Museum which he will use to illustrate his talk, Dr. Romer asserts that those of South American animals are the beat in America and those of prehistoric fishes particularly notable...
...inquisitive Professor Alfred Edwards Emerson, University of Chicago zoologist, scornfully denying that he and his family had suffered tropical discomfort. Predictions of insecticide manufacturers that tropical termites will direfully invade the U. S. are absurd, said he, because 1) most of the U. S. is too cold, and 2) fossil termites 30,000,000 years old show close kinship to species now living, so that if these oldtimers could have invaded the U. S., they would have done so long...
Dredging more than two thousand feet below the surface of the Atlantic Ocean, a Harvard University expedition has succeeded in taking fossil-bearing rock in place on the cliffs of the North American continental shelf for the first time, and has discovered evidence which upsets existing ideas as to the long geologic period of stability and quiet which was supposed to have continued unbroken since the Palaeozoic age, 160,000,000 years...
