Morphology

order + Rhynchocephalia

The phrase is transparently built from the noun 'order' (a taxonomic grouping) plus the proper taxon name 'Rhynchocephalia'; if a learner knows both constituents they can infer it refers to that taxonomic order of reptiles. This is a standard compositional naming pattern in biology and is cross-linguistically comparable, so the meaning is directly derivable from the parts.

Etymology

Order Rhynchocephalia comes from old Greek words: rhyncho meaning 'beak' and cephalia meaning 'head', because these reptiles had a beak-like snout. So, the name describes a group ('order') of related reptiles, like the living tuatara and many extinct relatives.
