Question

What is the feature that archaeopteryx has in common with reptiles and birds?

Answer 1

Archaeopteryx is more similar to small theropod dinosaurs than it is to modern birds. It has long been accepted that Archaeopteryx was a transitional form between birds and reptiles. Similar to reptilians, Archaeopteryx had a complete set of teeth. Unlike all living birds, Archaeopteryx had a flat sternum, a long, bony tail, gastralia, and three claws on the wing, believed to be used in grasping its prey or maybe trees. However, it also had characteristics of a modern bird, which included feathers, wings, furcula, and reduced fingers.
