However, mammals hail from the synapsids (which were once described as "mammal-like reptiles") and birds are descended from the dinosaurs (a group of Diapsida), both of which are reptiles.
Međutim, sisari potiču iz sinapsida (koji su jednom opisani kao "sisaroliki reptili") a ptice su potomci dinosaura (grupa Diapsida); obje grupe su reptili.
