Detailed explanation-1: -Archaeopteryx is considered by many to be the first bird, being of about 150 million years of age.
Detailed explanation-2: -The hunt for the ancestors of living birds began with a specimen of Archaeopteryx, the first known bird, discovered in the early 1860s. Like birds, it had feathers along its arms and tail, but unlike living birds, it also had teeth and a long bony tail.
Detailed explanation-3: -Birds evolved from a group of meat-eating dinosaurs called theropods. That’s the same group that Tyrannosaurus rex belonged to, although birds evolved from small theropods, not huge ones like T. rex. The oldest bird fossils are about 150 million years old.
Detailed explanation-4: -Archaeopteryx, discovered in 1861, was for a long time the only truly bird-like dinosaur – it’s from the Late Jurassic era (150 million years ago). Others closely related to birds, like Velociraptor, can be from the Late Cretaceous (100-66 million years ago), so they’d also had a lot of time to evolve independently.
