Страница 69 - O'er bog or steep, through strait, rough, dense, or rare, With head, hands, wings, or feet, pursues his way, And swims, or sinks, or wades, or creeps, or flies.
Страница 55 - Cope. Besides the smaller fishes, the reptiles no doubt supplied the> demands of his appetite. The ocean in which flourished this abundant and vigorous life, was at last completely inclosed on the west by elevations of sea-bottom, so that it only communicated with the Atlantic and Pacific at the Gulf of Mexico and the Arctic Sea.
Страница 187 - Alaska, where the bones are entombed in a wet and cold, often icy soil, the bones and tusks are almost as perfectly preserved as though they had been deposited but a score of years ago, while remains so situated that they have been subjected to varying conditions of dryness and moisture are always in a fragmentary state. As previously noted, several more or less entire carcasses of the mammoth have been discovered in Siberia, only to be lost; and while no entire animal has so far been found in Alaska,...
Страница 51 - Hoffmann, who was forming a collection of organic remains, discovered a specimen, which has conferred additional interest on this locality. Some workmen, on blasting the rock in one of the caverns of the interior of the mountain, perceived, to their astonishment, the jaws of an enormous animal attached to the roof of the chasm. The discovery was immediately made known to M.
Страница 56 - ... this mythical monster and place him on a foundation of firm fact. The most earnest of these was that of M. Oudemans, who expressed his belief in the existence of some rare and huge seal-like creature whose occasional appearance in southern waters gave rise * Cope : " The Vertebrata of the Cretaceous Formations of the West,
Страница 56 - ... living beings imprisoned and subjected to many new risks to life. The stronger could more readily capture the weaker, while the fishes would gradually perish through the constant freshening of the water. With the death of any considerable class the balance of food-supply would be lost, and many larger species would disappear from the scene. The most omnivorous and enduring would longest resist the approach of starvation, but would finally yield to inexorable fate ; the last one caught by the...
Страница 125 - ... of claws. The single blunt round claw among our bones shows, like the teeth, that Triceratops was herbivorous; it also pointed a little downward, and this tells that in the living animal the sole of the foot was a thick, soft pad, somewhat a,s it is in the elephant and rhinoceros, and that the toes were not entirely free from one another. There are less than a dozen vertebra1, and still fewer ribs, besides half a barrelful of pieces, from which to reconstruct a backbone 20 feet long. That the...
Страница 210 - ... are believed to have gathered in the swamps of New Zealand, and here the weaker died and left their bones. The mastodon must have looked very much like any other elephant, though a little shorter in the legs and somewhat more heavily built than either of the living species, while the head was a trifle flatter and the jaw decidedly longer. The tusks are a variable quantity, sometimes merely bowing outwards; often curving upwards to form a half circle ; they were never so long as the largest mammoth...
Страница 129 - Dinosaurs having dewlaps, that there would be no great likelihood of their possessing ruffs such as that of the Australian Chlamydosaurus (mantled lizard) to flap about their ears. Even Stegosaurus, with his bizarre array of great plates and spines, kept them on his back, out of the way. Such festal ornamentation would, however, more likely be found in small, active creatures, the larger beasts contenting themselves with plates and folds. Spines and plates usually leave some trace of their existence,...
