Synonyms

Centemodon (meaning "point tooth") is an extinct genus of basal [2] phytosaur from the Late Triassic Period. It lived in what is now Pennsylvania, United States. [2] It is classified as a nomen dubium . [3] It was found in the Red Sandstone Formation near the Schuyklill River. [4] Centemodon may have been related to Suchoprion . It was a small phytosaur, weighing no more than 200 kilograms (440 lb) when fully grown. [2]

Discovery and naming

Sometime before the Bone Wars, a palaeontologist known as Dr. Leo (surname unknown) discovered several fossil fragmentary teeth that later became the Centemodon holotype. [2] When Leo described the fragments, he was unsure of what they belonged to, and Leo did not name the fragments. They were eventually named in 1856 by Isaac Lea. [1]

Phytosaurs are an extinct group of large, mostly semiaquatic Late Triassic archosauriform reptiles. Phytosaurs belong to the order Phytosauria. Phytosauria and Phytosauridae are often considered to be equivalent groupings containing the same species, but some studies have identified non-phytosaurid phytosaurians. Phytosaurs were long-snouted and heavily armoured, bearing a remarkable resemblance to modern crocodilians in size, appearance, and lifestyle, as an example of convergence or parallel evolution. The name "phytosaur" means "plant reptile", as the first fossils of phytosaurs were mistakenly thought to belong to plant eaters.

<i>Leo the Lion</i> (TV series) 1966 anime television series

Leo the Lion is a sequel to the Japanese anime television series Jungle Emperor, or Kimba the White Lion. Osamu Tezuka had always wanted his story of Kimba to follow Kimba's entire life, and the Jungle Emperor/Kimba series was such a hit in Japan that Tezuka produced a sequel, without his American partners, in 1966. An English dub of the series was first broadcast in the United States in 1984 on the CBN Cable Network.

<i>Belodon</i> Extinct genus of reptiles

Belodon is a genus of phytosaur, a crocodile-like reptile that lived during the Triassic. Its fossils have been found in Europe and elsewhere. The type species, Belodon plieningeri, was named by prolific German paleontologist Christian Erich Hermann von Meyer in 1844.

Omosaurus is a dubious genus of extinct crurotarsan reptile, possibly a phytosaur, from the Late Triassic (Carnian) of North Carolina. Only scant remains are known, which makes Omosaurus hard to classify. The type, and only species, Omosaurus perplexus, was named and described in 1856 by Joseph Leidy.

<span class="mw-page-title-main">Pseudosuchia</span> Clade of reptiles

Pseudosuchia is one of two major divisions of Archosauria, including living crocodilians and all archosaurs more closely related to crocodilians than to birds. Pseudosuchians are also informally known as "crocodilian-line archosaurs". Despite Pseudosuchia meaning "false crocodiles", the name is a misnomer as true crocodilians are now defined as a subset of the group.

Rileyasuchus is a genus of phytosaur from the Rhaetian Magnesian Conglomerate of England. It has a confusing history, being associated with the taxonomy of Palaeosaurus and Thecodontosaurus, and being a replacement name for a preoccupied genus.

<i>Paleorhinus</i> Extinct genus of reptiles

Paleorhinus is an extinct genus of widespread basal phytosaur known from the Late Triassic. The genus was named in 1904 based on the type species Paleorhinus bransoni, which is known from Wyoming and Texas in the United States. Another valid species, Paleorhinus angustifrons from Bavaria, Germany, is also commonly referred to the genus. Paleorhinus had a length of about 2.5 meters.

<i>Rutiodon</i> Extinct genus of reptiles

Rutiodon is an extinct genus of mystriosuchine phytosaurs from the Late Triassic of the eastern United States. The type species of Rutiodon, Rutiodon carolinensis, encompasses a large number of skulls and assorted postcranial fossils discovered in the Cumnock Formation of North Carolina. Fossils referable to the species are also known from Pennsylvania, New Jersey, and Virginia. Rutiodon carolinensis is the most well-described species of phytosaur in eastern North America, though its validity as a natural taxon has been questioned. Some paleontologists also recognize a larger and more robust species, Rutiodon manhattanensis, which is known from teeth and postcranial fossils from New Jersey and Pennsylvania.

<i>Phytosaurus</i> Extinct genus of reptiles

Phytosaurus is a dubious genus of extinct parasuchid phytosaur found in an outcrop of the Keuper in Germany. Phytosaurus was the first phytosaur to be described, being done so by Georg Friedrich von Jaeger in 1828. The type species is P. cylindricodon and a second species, P. cubicodon, is also known.

<span class="mw-page-title-main">Mystriosuchini</span> Extinct tribe of reptiles

Mystriosuchini, historically known as Pseudopalatinae, is an extinct tribe of derived phytosaurs in the clade Leptosuchomorpha. As with all other phytosaurs, mystriosuchins lived during Late Triassic. The name is derived from the genus Mystriosuchus.

Arganasaurus is an extinct genus of prehistoric temnospondyl amphibian belonging to the family Metoposauridae that lived in Morocco during the Late Triassic (Carnian).

<i>Leptosuchus</i> Extinct genus of reptiles

Leptosuchus is an extinct genus of leptosuchomorph phytosaur with a complex taxonomical history. Fossils have been found from the Dockum Group and lower Chinle Formation outcropping in Texas, New Mexico, and Arizona, USA, and date back to the Carnian stage of the Late Triassic.

Compsemys is an extinct genus of prehistoric turtles from the Late Cretaceous and Paleocene of North America and possibly Europe. The type species C. victa, first described by Joseph Leidy from the Hell Creek Formation in Montana in 1856, and another probable species C. russelli, described in 2012, from Paleocene deposits in France. Its affinites have long been uncertain, but it has recently been considered to be the most basal member of Paracryptodira, despite the clade first appearing in the Late Jurassic, and is sometimes included in its own family, Compsemydidae. A revision in 2020 found Compsemydidae to be more expansive, also containing Riodevemys and Selenemys from the Late Jurassic of Europe, and Peltochelys from the Early Cretaceous of Europe.

Tarjadia is an extinct genus of erpetosuchid pseudosuchian, distantly related to modern crocodilians. It is known from a single species, T. ruthae, first described in 1998 from the Middle Triassic Chañares Formation in Argentina. Partial remains have been found from deposits that are Anisian-Ladinian in age. Long known mostly from osteoderms, vertebrae, and fragments of the skull, specimens described in 2017 provided much more anatomical details and showed that it was a fairly large predator. Tarjadia predates known species of aetosaurs and phytosaurs, two Late Triassic groups of crurotarsans with heavy plating, making it one of the first heavily armored archosaurs. Prior to 2017, most studies placed it outside Archosauria as a member of Doswelliidae, a family of heavily armored and crocodile-like archosauriforms. The 2017 specimens instead show that it belonged to the Erpetosuchidae.

Francosuchus is a dubious genus of probably basal phytosaur known from the Late Triassic of Bavaria, southern Germany. It was named by Oskar Kuhn in 1933 and the type species is Francosuchus broilii. In the same article Kuhn also named a second species Francosuchus latus. Both species were known solely from their holotypes, two partial skulls that were housed at the Bavarian State Collection for Palaeontogy and Geology. Both specimens were collected at Ebrach Quarry, bed number 13 from the late Carnian-aged Blasensandstein Member of the Hassberge Formation. As the holotypes were destroyed during World War II and poorly documented, Francosuchus and its species are usually considered to be nomina dubia.

<i>Protome</i> (genus) Extinct genus of reptiles

Protome is an extinct genus of parasuchid phytosaur from the Late Triassic of Arizona, represented by a single species, Protome batalaria. It is known from a single holotype incomplete, partially disarticulated skull and left lower jaw called PEFO 34034 from the Upper Lot's Wife beds, Sonsela Member of the Chinle Formation in Petrified Forest National Park. The skull was discovered in 2004 by Michelle Stocker and Bill Parker and was described by them as a specimen of Smilosuchus adamanensis. It was placed in the new genus Protome in 2012. The genus name Protome is the Greek word for an animal's face. The specific name batalaria is the Latin word for battleship, which is a reference to Battleship NW, the locality within Petrified Forest where the skull was found.

Dolerosaurus is an extinct genus of diapsid known from the early Late Triassic upper Lunz Formation of Austria. Dolerosaurus was first named by Richard J. Butler in 2013 and the type species is Francosuchus trauthi.

Nundasuchus is an extinct genus of crurotarsan, possibly a suchian archosaur related to Paracrocodylomorpha. Remains of this genus are known from the Middle Triassic Manda beds of southwestern Tanzania. It contains a single species, Nundasuchus songeaensis, known from a single partially complete skeleton, including vertebrae, limb elements, osteoderms, and skull fragments.
