Detailed explanation-1: -Fossil finds Archaeopteryx was first discovered in 1860 or 1861, when a solitary feather was unearthed from limestone deposits near Solnhofen, Germany. This feather, however, may have come from another, undiscovered proto-bird.

Detailed explanation-2: -It has long been accepted that Archaeopteryx was a transitional form between birds and reptiles, and that it is the earliest known bird.

Detailed explanation-3: -Archaeopteryx is a bird-like dinosaur that is the connecting link between dinosaurs and modern birds. These features make Archaeopteryx a transitional fossil between non-avian dinosaurs and birds. Thus, Archaeopteryx plays an important role in the study of the origin of birds and dinosaurs.

Detailed explanation-4: -Archaeopteryx is a transitional fossil because of its characteristics of both reptiles (dinosaurs) and birds. Basilosaurus and dorudon were ancient whales with tiny limbs and lived entirely in water. Ambulocetus is a more recent ancestor that had heavier leg bones and lived in both water and on land.
