Morphology

order + Therapsida

This phrase is fully compositional: 'order' denotes a taxonomic rank and 'Therapsida' is the name of the taxon, so together they straightforwardly mean the taxonomic grouping called Therapsida. Although the vocabulary is technical, a B1 learner who knows both constituents can derive the overall meaning without idiomatic interpretation.

Etymology

Order Therapsida names a group of ancient animals that looked like a mix of reptiles and early mammals. Picture a reptile with teeth and legs more like a small mammal; scientists call them 'mammal-like reptiles' because they show the early steps that led to 'mammals', and that is why fossils of order Therapsida help us understand how mammals began.
