Dinosaurs:
- They are a group of reptiles that lived between 245 and 66 million years ago.
- Approximately 66-65 million years ago, the non-avian dinosaurs became extinct. The reasons for extinction are still debated.
- However, avian dinosaurs (also known as modern birds) are still alive.
- According to the fossilized evidence, Birds are said to be one kind of dinosaur since they share common ancestry with the non-avian dinosaurs.
- Birds have evolved from theropods, dinosaurs that ate meat. Archaeopteryx, the first bird, was more closely related to dinosaurs than modern birds.
Similarities between dinosaurs and birds
The presence of scales and feathers, bipedal nature, laying of eggs, swivel-jointed wrists, hinged ankles, hollow bones, similarities in the respiratory system, and the presence of claws show that birds are closely related to dinosaurs. Thus, modern birds or avian dinosaurs are alive and the other types of dinosaurs are extinct.
