Eutherapsida

Reconstruction of Ulemosaurus svijagensis, copyright Dmitry Bogdanov.


Belongs within: Therapsida.
Contains: Dicynodontia, Cynodontia.

The Eutherapsida are the clade of synapsids uniting modern mammals with the Permian Dinocephalia. Members of the clade are characterised by a bowing of the zygomatic arch and increase in size of the temporal fenestra, together with loss of the olecranon ulnae and reduction of the fifth pedal digit to three phalanges.

The Hueneosauria are a clade of ichthyosaurs defined by Maisch & Matzke (2000) as the most exclusive clade including Mixosaurus cornalianus and Ophthalmosaurus icenicus.

Synapomorphies (from Maisch & Matzke 2000): External naris placed largely laterally; anterior margin of orbit regularly rounded; ramus occipitalis of supratemporal well developed; processus transversus pterygoidei absent; posterior dorsal centra discoidal; sacral ribs indistinguishable; caudal vertebral centra short; interclavicle of triradiate shape; radius and ulna distinctly shortened; posterior margin of ulna convex or straight; distal carpals II–IV of similar size; metacarpal V with straight or concave posterior margin or absent; pubis and ischium with strongly convex medial margins, not forming symphysis; less than five toes present.

Ichthyosauria

Reconstruction of Grippia longirostris, copyright Dmitry Bogdanov.

The Ichthyosauria are a major clade of marine reptiles known from the Lower Triassic to the lower Upper Cretaceous, members of which evolved a remarkably fish-like body form (Maisch & Matzke 2000).

Characters (from Maisch & Matzke 2000): Premaxillary rostrum elongate; naris displaced posteriorly, close to orbit; upper temporal fenestra with very considerable contribution of supratemporal; ectopterygoid absent; thoracal ribs articulating exclusively with centrum; manus and pes exhibiting hyperphalangy; fibula immobile relative to femur.

Belongs within: Parareptilia.

The Procolophonia are a clade of reptiles known from the mid-Permian to the late Triassic, including the large armoured Pareiasauria and the lizard-like Procolophonoidea. Some authors have also included the modern turtles in this clade.
