Archosaurs were one of the three infraclasses of diapsid reptiles. The group included Stegosauruses, Tyrannosaurus rexes, and...
Family Tree: Animalia (the animal kingdom) Tetropoda (critters adapted to life on land) Amniota (critters that lay eggs) Diapsida (snakes, crocs, lizards and birds) Archosauromorpha (closer to Archosauria than to lizards and snakes)
even other archosaurs.”Also,“This unique combination of features gave dinosaurs what is known as a “fully improved gait”. Evolution of this highly efficient method of walking also developed
Included among the archosaurs, or “ruling reptiles”, are prehistoric and modern crocodiles, and the now extinct thecodonts, pterosaurs and dinosaurs. Palaeontologists believe that both dinosaurs and crocodiles evolved, in the later years of the Triassic Period (c. 248-208 million years ago),...
What is megafauna in zoology? What was the longest dinosaur? Were archosaurs theropod dinosaurs? What evolved after the Cretaceous extinction? What was the heaviest dinosaur? Were there any Stegosaurus in the Cretaceous Period? What kind of herbivores lived during the Triassic Period?
Dinosaurs first evolved during the Triassic Period of the Mesozoic Era with the first dinosaurs appearing approximately 230 million years ago. They evolved from socket-toothed archosaurs, the same reptiles that gave rise to crocodilians.Answer and Explanation: ...
Sauria is the clade containing the most recent common ancestor of archosaurs and lepidosaurs, and all its descendants. Assuming turtles lie within Sauria, the group can be considered the crown group of diapsids, or reptiles in general.
All dinosaurs, whether large or small, quadrupedal or bidepal, fleet-footed or slow-moving, shared a common body plan.Identification of this plan makes it possible to differentiate dinosaurs from any other types of animal, even other archosaurs. Most significantly, in dinosaurs, the pelvis and ...
D.All dinosaurs, whether large or small, quadrupedal or bipedal, fleet-footed or slow-moving, shared a common body plan. Identification of this plan makes it possible to differentiate dinosaurs from any other types of animal, even other archosaurs. Most significantly, in dinosaurs, the pelvis ...
The Archosauria is the largest and most successful group of diapsids and includes crocodilians and dinosaurs. Birds are literally flying dinosaurs.Archosaurs also include the basal forms informally known as thecodonts because of their socketed teeth, them-selves a diverse group of terrestrial and ...
