In fact, this time had scarcely elapsed before the black points emerged at a little distance, and two jets of air mingled with vapor were noiselessly shot forth. The ubas approached, the harpoons were thrown at the same instant; one missed its mark, but the other struck one of the cetaceans near his tail.
It was not a lamantin, but one of that species of the order of cetaceans, which bear the name of the "dugong," for its nostrils were open at the upper part of its snout. The enormous animal rushed on the dog, who tried to escape by returning towards the shore.
That it was an extinct mammal of the whale tribe has since been placed beyond all doubt by discovery of the entire skull of another fossil species of the same family, having the double occipital condyles only met with in mammals, and the convoluted tympanic bones which are characteristic of cetaceans. Lapse of Time between Cretaceous and Eocene Periods. Maestricht Beds.
Cryptogamic vegetation would have the advantage over Phanerogamic; Hydrozoa over Corals; Crustacea over Insecta, and Amphipoda and Isopoda over the higher Crustacea; Cetaceans and Seals over the Primates; the civilization of the Esquimaux over that of the European.
"But you must admit that certain cetaceans do grow to significant size, since they're said to supply as much as 120 metric tons of oil." "That I've seen," the Canadian said. "I can easily believe it, Ned, just as I can believe that certain baleen whales equal 100 elephants in bulk. Imagine the impact of such a mass if it were launched at full speed!"
Now, the fact as to the comparative size of our own cetaceans and of 'geological' animals is just this. The Atlantosaurus of the Western American Jurassic beds, a great erect lizard, is the very largest creature ever known to have inhabited this sublunary sphere.
"What's the difference between a 'finback' and a 'humpback, Hank?" asked the boy, after the canvas had been stowed, the vessel under auxiliary steam having speed enough to keep up with the cetaceans, "are they 'right' whales?"
From this stage, in which the lamellae would be two-thirds of the length of the plates of baleen in the Balaenoptera rostrata, gradations, which may be observed in still-existing Cetaceans, lead us onward to the enormous plates of baleen in the Greenland whale.
Indeed when we consider the extraordinary compactness and rotundity of the modern cetaceans, as compared with the tall limbs and straggling skeleton of the huge Jurassic deinosaurs, I am inclined to believe that the tonnage of a decent modern rorqual must positively exceed that of the gigantic Atlantosaurus, the great lizard of the west, in propria persona.
The teeth of the cetaceans, with whom this painful falling-off begins, are no more teeth than his tongue is a tongue.
