Question

What are some Avian characteristics of Archosauria of the Reptilia?

Answer 1

Archosaurs belong to the group diapsids, meaning groups that have two holes behind the eye socket. The modern-day diapsids mainly include crocodilians and birds. so to answer the Avian characteristics of Archosauria of the Reptilia we need to look at the commonalities between the two groups. Here are some:

• Firstly the vertebral structure
• Scales on some parts of the body
• Amniotic eggs with shells

These are some prominent properties.

As dinosaurs were also a part of Archosaurs, we could also compare between the Avians and the dinosaurs(Some)

• Hollow bone structure
• presence of the wishbone structure
• Feathers
• The wing mechanism of avians has been found to be present in archaeological data from dinosaurs

These are some commonalities between avians and dinosaurs.

There are details probably yet to be discovered by paleontologists. But a intersect between Avians and reptiles/dinosaurs gets us closer to the commonalities between Avians and the major parent group Archosaurs.

Good Luck
