Balearosaurus is an extinct genus of moradisaurine captorhinid from the Permian of Spain. The type species is B. bombardensis. [1]
Captorhinidae is an extinct family of tetrapods, typically considered primitive reptiles, known from the late Carboniferous to the Late Permian. They had a cosmopolitan distribution across Pangea.
Labidosaurus is an extinct genus of reptile from the Permian period of North America. Fossils have been discovered in Texas.
Prionosuchus is an extinct genus of large temnospondyl. A single species P. plummeri, is recognized from the Early Permian. Its fossils have been found in what is now northeastern Brazil.
Captorhinus is an extinct genus of captorhinid reptiles that lived during the Permian period. Its remains are known from North America and possibly South America.
Labidosaurikos is a genus of extinct captorhinid anapsid reptile that lived around 279 to 272 million years ago during Kungurian age of the lower Permian. The American paleontologist John Willis Stovall first described Labidosaurikos in 1950, naming it "Labidosaurus like" for the striking similarity of the holotype skull of his specimen to the cranial anatomy of another captorhinid Labidosaurus hamatus. Labidosaurus or generally called "lipped lizard" is another genus of the family Captorhinidae whose name is derived from the Greek for "forceps lizard" based on τσιμπίδα and σαυρος ("lizard")
Euryodus is an extinct genus of microsaur within the family Gymnarthridae. Euryodus is a Lepospondyl from the clade Microsauria that lived during the Lower Permian. The name comes from Greek, meaning ‘broad-tooth’. It has been found in the southern half of North America, from its original discovery in Texas up to Utah.
Reiszorhinus is an extinct genus of Early Permian captorhinid known from the United States. The type species is Reiszorhinus olsoni. Fossils have been found from the Waggoner Ranch Formation in north-central Texas. It is distinguishable by its recurved teeth and extremely large Meckelian foramen on the inner surface of the lower jaw. It has been considered a primitive member of its family because it has a single tooth along the margins of the jaws. While most single-tooth-rowed captorhinids are small, Reiszorhinus is relatively large. However, Reiszorhinus differs from other large captorhinids in that the cheek region is not wide and expanded.
Gansurhinus is an extinct genus of moradisaurine captorhinid known from the Middle Permian Qingtoushan Formation of the Qilian Mountains and the Late Permian Naobaogou Formation in the Daqing Mountains of China. It was first named by Robert R. Reisz, Jun Liu, Jin-Ling Li and Johannes Müller in 2011 and the type species is Gansurhinus qingtoushanensis. A second species, Gansurhinus naobaogouensis, was described in 2023 based on a relatively complete skeleton of an immature individual.
Romeria is an extinct genus of Early Permian captorhinid known from Texas of the United States. It was first named by Llewellyn Ivor Price in 1937 and the type species is Romeria texana. R. texana is known from the holotype MCZ 1480, a three-dimensionally preserved skull. It was collected in the Archer City Bonebed 1 site, from the Archer City Formation, dating to the Asselian stage of the Cisuralian epoch, about 299–294.6 million years ago. A second species, Romeria primus, was first named by Clark and Carroll in 1973. In 1979, it was corrected as Romeria prima by Heaton. R. prima is known from the holotype MCZ 1963, a three-dimensionally preserved skull. It was collected in the Cottonwood Creek site, from the same horizon as the type species.
Protocaptorhinus is an extinct genus of Early Permian captorhinid reptile known from Texas of the United States. It is known from the holotype MCZ 1478, a three-dimensionally preserved partial skull. It was collected in the Rattlesnake Canyon site from the Petrolia Formation. It was first named by Clark and Carroll in 1973 and the type species is Protocaptorhinus pricei. The generic name means "first Captorhinus" and the specific name honours Llewellyn Ivor Price.
Euconcordia is an extinct genus of Late Carboniferous captorhinid known from Greenwood County, Kansas of the United States.
Saurorictus is an extinct genus of Late Permian captorhinid known from Western Cape Province of South Africa.
Rhiodenticulatus is an extinct genus of Early Permian captorhinid known from Rio Arriba County, New Mexico of the United States.
Acrodenta is an extinct genus of Late Permian captorhinid known from Marrakech-Tensift-Al Haouz of Morocco.
Baeotherates is an extinct genus of Early Permian captorhinid reptile known from Oklahoma, United States.
Gecatogomphius is an extinct genus of Middle Permian captorhinid with multiple tooth rows known from the Kirov Oblast and the Republic of Tatarstan of Russia.
Opisthodontosaurus is an extinct genus of captorhinid reptile from the Early Permian of Oklahoma. The type species Opisthodontosaurus carrolli was named in 2015 on the basis of several articulated skeletons from the Dolese Brothers Limestone Quarry near Richards Spur. Before the description of these skeletons, the jaws and teeth of Opisthodontosaurus carrolli were thought to belong to a species of lepospondyl amphibian called Euryodus primus. Although captorhinid reptiles and lepospondyl amphibians are distantly related, the two species show a remarkable degree of evolutionary convergence in their dental anatomy. Both were likely durophagous, eating hard-shelled invertebrates.
Labidosauriscus is an extinct genus of anapsid reptile from the Permian period of North America. Fossils have been discovered in Oklahoma.
Procuhy is an extinct genus of dvinosaurian temnospondyl amphibian in the family Trimerorhachidae represented by the type species Procuhy nazariensis from the Early Permian of Brazil.
Rhodotheratus is an extinct genus of captorhinid from the Early Permian Hennessey Formation of Oklahoma. The type species is R. parvus.
