Question

Write note on extinct reptiles

Answer 1

Reptiles are tetrapod animals in the classReptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.Between 280 and 65 million years ago, a multitude of reptiles occupied ecological niches comparable to those filled by mammals and birds today. With more than 700 species, their remains exhibit an astonishing, often bizarre, variety of form and habit. This "Age of Reptiles" opened in the Permian Age (280-225 million years ago), when early reptiles gained ascendancy over the amphibians, and it lasted throughout the Mesozoic Age (225-65 million years ago). These prehistoric creatures are commonly known as dinosaurs which comes from the Greek meaning - terrible or powerful lizards.
