Answer 1

Answer:

Explanation:

An anapsid is an amniote whose skull lacks one or more skull openings (fenestra) near the temples. Traditionally, the Anapsida are the most primitive subclass of reptiles, the ancestral stock from which Synapsida and Diapsida evolved, making anapsids paraphyletic.

Answer 2

Answer:

An anapsid is an amniote whose skull lacks one or more skull openings (fenestra) near the temples.[1] Traditionally, the Anapsida are the most primitive subclass of reptiles, the ancestral stock from which Synapsida and Diapsida evolved, making anapsids paraphyletic. It is however doubtful that all anapsids lack temporal fenestra as a primitive trait, and that all the groups traditionally seen as anapsids truly lacked fenestra.
