Morphology

Thecodontia = theco + dont + ia

The components 'theco' and 'dont' relate to 'socket' and 'tooth', but the specific meaning of an extinct group of reptiles is not derivable from these parts.

Etymology

Thecodontia comes from Greek parts theco- ('case' or 'socket') and -odont ('tooth'), so it literally means 'socket-toothed' reptiles. This is why the name fits: their teeth sat in sockets, and you can remember the -odont part from orthodontist ('tooth' doctor).
