Detailed explanation-1: -Archaeopteryx was first described as the ‘missing link’ between reptiles and birds in 1861 – and is now regarded as the link between dinosaurs and birds. Only 12 specimens have ever been found and all are from the late Jurassic of Bavaria, now Germany, dating back approximately 150 million years.
Detailed explanation-2: -Archaeopteryx is an iconic fossil, often thought of as the ‘missing-link’ between dinosaurs and birds.
Detailed explanation-3: -It is today, known as a transitional species between the two groups-reptiles and birds. Archaeopteryx had jaws with teeth and a long bony tail like the dinosaurs, broad wings and feathers like birds, and skeletal features of both. Q. The fossil of Archaeopteryx is the missing link between reptiles and birds.
Detailed explanation-4: -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.
