Dian told me they were tandorazes, or tandors of the sea, and that the other, and more fearsome reptiles, which occasionally rose from the deep to do battle with them, were azdyryths, or sea-dyryths Perry called them Ichthyosaurs. They resembled a whale with the head of an alligator.
These sea monsters disported along the Pacific shore over northern California in Triassic times, and the bones of immense members of the family occur in the Jurassic strata of Wyoming. Like whales and seals, the ichthyosaurs were descended from land vertebrates which had become adapted to a marine habitat. PLESIOSAURS were another order which ranged throughout the Mesozoic.
Then, by slow degrees, the mountains of Brazil, with their mines of glittering gems, appeared above the surface of the waters, amid which huge reptile-like whales, ichthyosaurs, plesiosaurs, and cetiosaurs buffeted the billows, and vast saurians, lizards, and alligators, rivalling the elephant in bulk, and twice his length such as the megalosaurus, the iguanodon, and teleosaurus crawled along the slimy shores; while giant birds, with wide-spreading feet, stalked across the newly-formed plains, or flew shrieking, with wings of prodigious expanse skimming the glittering sea, the lords paramount of this lower world.
It is evident from their fish-like vertebrae, their paddles, resembling those of a porpoise or whale, the length of their tail, and other parts of their structure, that the Ichthyosaurs were aquatic. Their jaws and teeth show that they were carnivorous; and the half-digested remains of fishes and reptiles, found within their skeletons, indicate the precise nature of their food. Mr.
And meanwhile, in a ring about the islet, not daring to come near for terror of the quicksand, crocodiles and alligators and ichthyosaurs, with upturned, gaping snouts, watched the struggle greedily. As the lower part of his neck was drawn down into the quicksand, the colossus lost the power to move his head quickly enough to evade the attacks of his horrid assailants.

With the dawn of the tertiary period, the reign of the reptiles begins to wane, and the reign of the mammals to set in at last in real earnest. In place of the ichthyosaurs we get the huge cetaceans; in place of the deinosaurs we get the mammoth and the mastodon; in place of the dominant reptile groups we get the first precursors of man himself.
The chronicle of the later Cretaceous is a story of devastation. The reduction of the cyeads is insignificant beside the reduction or annihilation of the great animals of the Mesozoic world. The skeletons of the Deinosaurs become fewer and fewer as we ascend the upper Cretaceous strata. The Ichthyosaurs and Plesiosaurs vanish from the waters.
Your brains must be one fossiliferous deposit, in which gaur and sambur, hog and tiger, rhinoceros and elephant, lie heaped together, as the old ichthyosaurs and plesiosaurs are heaped in the lias rocks at Lyme. And therefore I like to think of you. I try to picture your feelings to myself.
Although reptiles appeared first in the period known as the Carboniferous Age, or age of plant life, they did not attain their greatest development until Jurassic and Cretaceous times, when many were of prodigious size and ruled the world. The gigantic ichthyosaurs, mesosaurs, and dinosaurs held dominion over the sea and land, and the monster flying reptile, the pterodactyl, over the air.
