A rain of animals is a rare meteorological phenomenon in which flightless animals fall from the sky. Such occurrences have been reported in many countries throughout history. [1]
The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes. [1] Tetrapods (under the apomorphy-based definition used on this page) are categorized as animals in the biological superclass Tetrapoda, which includes all living and extinct amphibians, reptiles, birds, and mammals.
A = Anapsid, B = Synapsid, C = Diapsid. It was traditionally assumed that first reptiles were anapsids, having a solid skull with holes only for the nose, eyes, spinal cord, etc.; [10] the discoveries of synapsid-like openings in the skull roof of the skulls of several members of Parareptilia, including lanthanosuchoids, millerettids, bolosaurids, some nycteroleterids, some procolophonoids and ...
Early pterosaurs have long been considered particularly cumbersome locomotors due to the presence of large cruropatagia, but they too appear to have been generally efficient on the ground. [ 142 ] The forelimb bones of azhdarchids and ornithocheirids were unusually long compared to other pterosaurs, and, in azhdarchids, the bones of the arm and ...
These Aesculapian snakes originally escaped from the Welsh Mountain Zoo, in Colwyn Bay, Conwy, around 50 years ago and there have been a total of 240 snakes found in the surrounding area since.
Why did it have to be snakes?” The reptile, christened Tachymenoides harrisonfordi, measures 16 inches long and is a pale yellowish-brown colour with black spots and a black belly.

Held, Jr. The title pays homage to Rudyard Kipling's Just So Stories, [1] [a] but the "tales" are strictly scientific, explaining how a wide range of animal features evolved, in molecular detail. The book has ...
The skull of a snake differs from a lizards in several ways. Snakes have more flexible jaws, that is, instead of a juncture at the upper and lower jaw, the snake's jaws are connected by a bone hinge that is called the quadrate bone.
