Morphology

Labyrinthodontia = Labyrinthodont (opaque) = labyrinth + odont + ia

Adding the taxonomic suffix '-ia' to form a group name from 'Labyrinthodont' is a regular morphological step, but it yields a technical collective term.

Etymology

Labyrinthodontia comes from two old Greek words, labyrinthos 'maze' and odont 'tooth'. These extinct amphibians had teeth that were maze-like inside, so the name means 'maze-tooth' and helps explain their complex teeth.
