Tuditanomorpha

Tuditanomorpha is a suborder of microsaur lepospondyls. Tuditanomorphs lived from the Late Carboniferous to the Early Permian and are known from North America and Europe. Tuditanomorphs have a similar pattern of bones in the skull roof. Tuditanomorphs display considerable variability, especially in body size, proportions, dentition, and presacral vertebral count. Currently there are seven families of tuditanomorphs, with two being monotypic. Tuditanids, gymnarthrids, and pantylids first appear in the Lower Pennsylvanian. Goniorhynchidae, Hapsidopareiontidae, Ostodolepidae, and Trihecatontidae appear in the Late Pennsylvanian and Early Permian.
