Question

What is temporal arch?

Answer 1

This is the structure of the temporal region of the reptilian skull.

The projecting ledge lateral to the superior temporal fenestra is called the superior temporal arch, and the bony bar below the inferior temporal fenestra is called the inferior temporal arch (Hyman’s Comparative Vertebrate Anatomy. – 3rd ed. / edited by Marvalee H. Wake).

The temporal arch is significant for further evolution of vertebrate skull.
