Reptiliomorphs (order Reptiliomorpha) are amphibians and primitive reptiles that gave rise to true reptiles. The term "reptiliomorph" is fairly loose; it contains many families of species that were until recently believed to be unrelated. The largest subgroup of reptiliomorphs is the Anthracosaurs, which contains all but one of the families in Reptiliomorpha.
