Answer:

birds

Explanation:

Archaeopteryx is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. Archaeopteryx is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of Archaeopteryx indicates that it was similar to that of nonavian theropod dinosaurs, i.e.,  dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, Archaeopteryx had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.
