Archaeopteryx is considered the 1st Bird.
It was from a long line of Avian dinosaurs which are very very closely related to the Raptor family of Therapod Dinosaurs.
The morphology of avian dinosaurs and modern birds are so similar many scientist class birds as avian dinosaurs.
The oldest bird fossil Archaeopteryx is a transitional form between reptiles and birds and is cited as evidence Describe three additional pieces of evidence for this claim?
well Darwin knew that reptiles could change into birds and an archaeopteryx is basically a reptile with wings
An archaeopteryx is an early form of the bird. The scientists discovered an archaeopteryx fossil.

The fossil that was found in Bavaria, Germany, is the Archaeopteryx.
Archaeopteryx is a Jurassic fossil bird that shares both bird and reptile features; it is widely accepted as the earliest and most primitive known bird. Fossils show the presence of wings and feathers, as in birds, but also teeth (which modern birds do not have), claws on the wings, and a long, lizard-like tail, with tail vertebrate, such as with reptiles (March 2001). The description of the first intact specimen in 1861 (two years after Charles Darwin published The Origin of Species), set off a firestorm of debate about evolution and the role of transitional fossils that endures to this day.
Well, first of all, if the animal did not have a tail or teeth it would not be like archaeopteryx. The description must be more specific. The fact that archaeopteryx was so birdlike itself supports the hypothesis that archaeopteryx was related to, if not the ancestor of birds today.

The transition of phyla of organisms over time. That is the great strength of the fossil record; evolution shown in the sedimentary rock.
