It has been suggested to me that this difficulty may be evaded by considering pterodactyles and carinate birds as independent branches from one side of an ancient common trunk, while similarly the Dinosauria and struthious birds are taken to be independent branches from the other side of the same common trunk; the two kinds of birds resembling each other so much on account of their later development from that trunk as compared with the development of the reptilian forms.
THE ANCESTRY OF SURVIVING REPTILIAN TYPES. We will consider first the evolution of the few reptilian types which have survived to the present. Crocodiles, the highest of existing reptiles, are a very ancient order, dating back to the lower Jurassic, and traceable to earlier ancestral, generalized forms, from which sprang several other orders also.
His status was still to assure. They began with a few mild tricks. Shuffle the Brogan followed Hot Back. Thorpe took all of it good-naturedly. Finally a tall individual with a thin white face, a reptilian forehead, reddish hair, and long baboon arms, suggested tossing in a blanket. Thorpe looked at the low ceiling, and declined.
Tommy should come out into a tree-fern forest whose lush vegetation would hide the sky, and which furnished a lurking place not only for strange reptilian monsters akin to those of the long-dead past of Earth, but for the bands of ragged, half-mad human beings who were outlaws from the civilization of which Denham and Evelyn had seen proofs. Tommy reached the third bend in the Tube.
She smiled at Ashton. "That was the Dry Mesa reptilian age. I first learned to handle a 'gun' shooting at rattlers. There were so many we had to make it a rule to kill everyone we could. But there hasn't been one killed so near the house for years." "They often go in pairs. This one, though, may have been a lone stray," added Gowan. He looked at his employer.
Their teeth were a little more complicated and specialized than the teeth of their reptilian cousins. Between their scales were small and sparse hairs. Almost nothing but their jaws remain to-day to tell us anything about them. But in this humble little creature of the Mesozoic, utterly insignificant beside the tremendous reptiles of the time, we discern the ancestor of the mammals.
We might, however, have anticipated, from its rich reptilian fauna, that the contemporaneous inhabitants of the sea of the Keuper period would be very numerous, should we ever have an opportunity of bringing their remains to light. This, it is believed, has at length been accomplished, by the position now assigned to certain Alpine rocks called the "St.
The prey was not far distant and as the hunter approached it, he took silently to the trees and still in his nostrils was the faint reptilian odor that spoke of a great creature which he had never yet seen except as a denser shadow among the dense shadows of the night; but the odor was of such a faintness as suggests to the jungle bred the distance of absolute safety.
Preying continually upon the herbivora were the meat-eaters, large and small wolves, hyaenadons, panthers, lions, tigers, and bear as well as several large and ferocious species of reptilian life.
The diminution in reptilian life was the most noticeable change in the fauna of northern Caspak. Here, however, were forms they had not met elsewhere, several of which were of gigantic proportions. According to their custom all, with the exception of the man on guard, sought sleep early, nor, once disposed upon the ground for slumber, were they long in finding it.
