Question

Name three traits of Archaeopteryx that make it theropod-like (that is, are traits that modern birds do not have but some theropod dinosaurs do).

Answer 1

Traits of Archaeopteryx that are theropod-like include its jaw with teeth, a long bony tail, and a non-fused pelvis. These features distinguish it from modern birds and align it more closely with theropod dinosaurs.

Step-by-step explanation:

Three traits oat make it theropod-like include its jaw with teeth, a long bony tail, and the absence of a fused 'bird-like' pelvis. Unlike modern birds, Archaeopteryx possessed a jaw with sharp teeth, a feature commonly found among theropod dinosaurs. Furthermore, Archaeopteryx had a long bony tail, which is a characteristic trait of many non-avian theropods, as modern birds possess a shortened tail structure known as a pygostyle. Lastly, the pelvis of Archaeopteryx was not fully fused like that of modern birds, showing a closer resemblance to theropod dinosaurs.
