Morphology

synapsid + reptile

This is a straightforward modifier+noun phrase: 'synapsid' specifies a subtype of 'reptile', so the combined meaning is simply a reptile that is synapsid. If a learner already knows the technical term 'synapsid' (an animal with a particular skull opening) and 'reptile', the meaning is directly inferable and follows regular English composition patterns.

Etymology

Synapsid reptile The name synapsid reptile comes from their skull: synapsid animals had a single pair of holes just behind the eyes, so their skulls looked more like early mammals than modern reptiles. That's why scientists call them the 'ancestors' of mammals.
