Ankistrodon is an extinct genus of archosauriform known from the Early Triassic Panchet Formation of India. First thought to be a theropod dinosaur, it was later determined to be a proterosuchid. The type species is A. indicus, described by prolific British zoologist Thomas Henry Huxley in 1865. One authority in the 1970s classified Ankistrodon as a senior synonym of Proterosuchus. Ezcurra (2023) found Ankistrodon to be a nomen dubium, as the teeth are indistinguishable from those of Proterosuchus. A second Indian proterosuchid from the same formation, Samsarasuchus, was also described in the same study, making it the only known valid proterosuchid from India.
Chasmatosuchus was an archosauriform reptile from the early Triassic period of European Russia. One of the earliest described archosauriforms, it was over 2 m long and is thought to have behaved like a modern crocodile. Its mouth had two distinct features: the top of its jaw hooked downwards to aid in holding prey, and the upper palate was lined with a row of teeth—a primitive feature lost in later archosaurs.
Proterosuchidae is an early family of basal archosauriforms whose fossils are known from the Late Permian and the Early Triassic. The highest diversity of genera is known from European Russia, but fossils are also known from South Africa, India, China, Australia, Brazil and possibly Argentina. The name comes from Greek πρότερο- ("first") and σοῦχος ("crocodile").
Parasuchus is an extinct genus of basal phytosaur known from the Late Triassic of Andhra Pradesh and Madhya Pradesh, India. At its most restricted definition, Parasuchus contains a single species, Parasuchus hislopi. Parasuchus hislopi is one of several species belonging to a basal grade of phytosaurs, typified by the genus Paleorhinus. Historically, Paleorhinus has been known from better-described fossils, and many species have been lumped into that genus. Parasuchus hislopi, despite being described earlier than Paleorhinus, was considered an undiagnostic chimera until new neotype fossils were described in the late 1970s. Parasuchus hislopi and the two unambiguously valid species of Paleorhinus are all closely related; some authors have historically described them all under the species Paleorhinus, while others place the two Paleorhinus species into Parasuchus according to the principle of priority.
Malerisaurus is an extinct genus of archosauromorph known from Telangana of India and Texas of the USA.
Archosaurus is an extinct genus of carnivorous proterosuchid archosauriform reptile. Its fossils are dated to the latest Permian of Russia and Poland, it is one of the earliest known archosauriforms. The type and only species is Archosaurus rossicus, known from several fragmentary specimens which cumulatively represent parts of the skull and cervical vertebrae. It would have been 3 metres (9.8 ft) long when fully grown.
Indolyrocephalus is an extinct genus of prehistoric amphibian belonging to the family Trematosauridae. It contains a single species, I. huxleyi, from the Early Triassic Panchet Formation of India. It was initially classified in Gonioglyptus, then into its own genus Indolyrocephalus, and then back into Gonioglyptus, but is presently placed in Indolyrocephalus once again.
Gonioglyptus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It is known from the Early Triassic Panchet Formation of India. It contains two species: G. longirostris and G. fragilis. The species G. kokeni from Pakistan has since been reclassified into Aphaneramma.
Pachygonia is an extinct genus of temnospondyl amphibian from the Early Triassic Panchet Formation of India. It contains a single species, P. incurvata. It may potentially be a member of the family Brachyopidae.
Jaikosuchus is an extinct genus of proterosuchid archosauriform. It contains a single species, J. magnus. Fossils have been found from European Russia that date back to the upper Olenekian stage of the Early Triassic.
Nambalia is a genus of basal sauropodomorph dinosaur. It lived during the Late Triassic period in what is now Telangana, central India. It is known from the holotype ISI R273, parts 1–3, partially articulated postcranial material and from the paratypes ISI R273, parts 4-29, including partial postcrania of at least two individuals of different sizes found closely associated and one of them is nearly the same size as the holotype.
Jaklapallisaurus is a genus of unaysaurid sauropodomorph dinosaur. It lived during the Late Triassic period in what is now Telangana, central India.The genus is monotypic, only including the species Jaklapallisaurus asymmetricus.
The Pranhita–Godavari Basin is a northwest–southeast striking geological structural basin in central India. The basin contains up to 7 kilometres of sedimentary strata of late Carboniferous/Early Permian to Cretaceous age. The basin is 400 km in length with a width of about 100 km and is terminated by the coast of the Indian Ocean on the southeast end.
The Lower Maleri Formation is a sedimentary rock formation found in Andhra Pradesh and Telangana, India. It is the lowermost member of the Pranhita–Godavari Basin. It is of late Carnian to early Norian age, and is notable for its fossils of early dinosaurs, including the basal saurischian Alwalkeria.
The Lower Dharmaram Formation is a sedimentary rock formation found in Telangana, India. It is one of the formations of the Pranhita–Godavari Basin. It is of latest Norian and Rhaetian ages, and is notable for its fossils of early dinosaurs.
Vonhuenia is an extinct genus of proterosuchid, a basal archosauriform from the Early Triassic of Russia. Fossils have been found in the Vokhminskaya Formation, along the Vetluga River that are Induan in age, making Vonhuenia one of the earliest archosauriforms.
The Yerrapalli Formation is a Triassic rock formation consisting primarily of mudstones that outcrops in the Pranhita–Godavari Basin in southeastern India. The Yerrapalli Formation preserves fossils of freshwater and terrestrial vertebrates as well as trace fossils of invertebrates. The tetrapod fauna includes temnospondyl amphibians, archosauromorph reptiles, and dicynodonts.
Gamosaurus is an extinct genus of proterosuchid archosauriform. It contains a single species, Gamosaurus lozovskii, named by Vitalii Georgievich Ochev in 1979.
Pamela Lamplugh Robinson was a British paleontologist who worked extensively on the fauna of the Triassic and Early Jurassic of Gloucestershire and later worked in India on the Mesozoic and Gondwanan fauna. She helped establish the geology unit at the Indian Statistical Institute and directed research in vertebrate paleontology of India in the 1960s.
Samsarasuchus is an extinct genus of archosauriform reptile from the Early Triassic of India. This genus has one known species, Samsarasuchus pamelae. Samsarasuchus lived a few million years after the Permian-Triassic extinction, the largest known mass extinction event. It was a member of the Proterosuchidae, a group of successful crocodile-like reptiles that survived the extinction event and were among the earliest successful archosauromorphs.
