Include Lizards Sauria:
The scaly reptiles (Squamata) include lizards Sauria the lizards (Sauria) and snakes (Serpentes) of to¬day, their respective ancestors being first known from the Jurassic and Cretaceous. Lizards differ from the tuatara in having only a single temporal aperture. Otherwise the structural similarities between Sphenodon and certain liz¬ards are so striking that the former was at one time classed with the Sauria.It is not un¬reasonable to assume that both Rhynchocephalia and Sauria sprang from the Eosuchia, though alternative views are also held. Of extinct lizards the best known are probably the dolicho-saurs and mosasaurs of the Cretaceous, the former a semiaquatic group related to the moni¬tor lizards (Varanus) of today, and the mosa¬saurs, one of which attained a length of twenty-five feet, marine reptiles with paddle-shaped limbs.
See Also Snakes Lizards Belong:
Snakes lizards belong and lizards belong to the same large order, and though they possess many characteristics in common, each belongs to a dis¬tinct suborder. The fundamental difference lies in the skeleton. Snakes lizards belong are highly specialized animals and beautifully adapted to their habits of living. Zoologists tell us that they once had legs and were lizards.Lizards and Snakes lizards belong belong to the same large order, and, though they possess many characteristics in common, each belongs to a distinct suborder. The layman is inclined to describe a lizard as a snakelike animal with four legs, eyelids, external ear openings, and a detachable tail. There are, however, many species of lizards which possess none of these characteristics; in fact, there are some that can scarcely be distinguished from Snakes lizards belong. The fundamental difference lies in the skeleton.
On The Other Hand See Majority Lizards Insect:
The majority lizards insect of lizards are insect feeders. A few are can¬nibalistic, and some are nearly or wholly vegetarian, feeding on the blossoms and buds of plants. Lizards, like snakes, shed the skin as they feed and grow. As a rule it is shed in patches though some species, such as the alligator lizard, shed it all in one piece as does a snake.The body of a lizard is covered with scales, but the scales are not covered by a. delicate skin as they are in the snake. This gives many lizards a rough, spiny, or prickly feeling to the touch. The colors in the scales combine to form definite pat¬terns or markings on the body of lizards. Lizards are cold-blooded creatures, hence feel cold to the touch. Eyes: The majority lizards insect of lizards in the United States have functional eyes with movable eyelids. The two exceptions are the geckos, which are night wanderers, and the rather rare xantusias or night lizards.
