Embolomeri is an order of tetrapods or stem-tetrapods, possibly members of Reptiliomorpha. Embolomeres first evolved in the Early Carboniferous (Mississippian) Period and were the largest and most successful predatory tetrapods of the Late Carboniferous (Pennsylvanian) Period. They were specialized semiaquatic predators with long bodies for eel-like undulatory swimming. Embolomeres are characterized by their vertebral centra, which are formed by two cylindrical segments, the pleurocentrum at the rear and intercentrum at the front. These segments are equal in size. Most other tetrapods have ple

Diplovertebron (from , 'double' and , 'vertebra') is an extinct genus of embolomere that lived in the Late Carboniferous period (Moscovian), about 310 million years ago. Diplovertebron was a medium-sized animal, around 50 cm in length. Members of the genus inhabited European Carboniferous swamps in what is now the Czech Republic. They were closely related to larger swamp-dwelling tetrapods like Proterogyrinus and Anthracosaurus. However, Diplovertebron were much smaller than these large, crocodile-like creatures. Known from a single species, Diplovertebron punctatum, this genus has had a

Eoherpeton is the only genus of the family Eoherpetontidae in the extinct suborder Embolomeri. It is known from the Visean and Namurian (now Serpukhovian and lower Bashkirian) stages of the Carboniferous of Scotland.

Pholiderpeton (from , 'horny scale' and , 'creeping thing') is an extinct genus of embolomere amphibian which lived in the Late Carboniferous period (Bashkirian) of England. The genus was first named by Thomas Henry Huxley in 1869 to include the species P. scutigerum, based on the disarticulated front half of a skeleton discovered near Bradford, Yorkshire.

Anthracosaurus is an extinct genus of embolomere that lived during the Late Carboniferous (around 315 million years ago) in what is now Scotland, England, and Ohio. Measuring around long, it was a large, aquatic eel-like predator. It has a robust skull about in length with large teeth in the jaws and on the roof of the mouth. Anthracosaurus probably inhabited swamps, rivers and lakes. Its name is Greek for "coal lizard".

Neopteroplax is an extinct genus of eogyrinid embolomere closely related to European genera such as Eogyrinus and Pteroplax. Members of this genus were among the largest embolomeres (and Carboniferous tetrapods in general) in North America. Neopteroplax is primarily known from a large (~40 cm) skull found in Ohio, although fragmentary embolomere fossils from Texas and New Mexico have also been tentatively referred to the genus. Despite its similarities to specific European embolomeres, it can be distinguished from them due to a small number of skull and jaw features, most notably a lower suran

Pteroplax is an extinct genus of embolomerous anthracosaur. Only one species (P. cornutus Hancock & Atthey, 1868) has been described; the skull table noted is the lectotype of this species. Pteroplax dates from the late Carboniferous Period, about 315 million years ago. It is known with certainty only from Newsham in Blyth, Northumberland, England. At that site, it shared a coal-swamp lake habitat with the larger embolomere, "Eogyrinus" (whose name is a junior synonym of Pholiderpeton Huxley, 1869). Pteroplax probably grew up to about in length and was largely aquatic, feeding upon fish and sm
