Solenodonsaurus ("single-tooth lizard") is an extinct genus of reptiliomorphs that lived in what is now Czech Republic, during the Westphalian stage.

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

Eldeceeon is an extinct genus of reptiliomorph from the Mississippian (early Carboniferous) of Scotland. It is known from two fossil specimens found within the Viséan-age East Kirkton Quarry in West Lothian. The type and only species, E. rolfei, was named in 1994. Eldeceeon is thought to be closely related to embolomeres, but it has several distinguishing features including long limbs and a short trunk. Initially known from two crushed partial skeletons, additional specimens have been reported by Ruta & Clack (2006). Eldeceeon was redescribed by Ruta, Clack, & Smithson (2020). The redescriptio
