Platyoposaurus was a temnospondyl from the Middle Permian epoch about 270-268 Mya. [1]
One of the discoveries includes a skull 28 cm long with a purported body length of 250 cm representing a carnivorous adult specimen. [2]
The fossil remains were found in Belebey in Bashkortostan, Russia; the name Platyoposaurus means "flat-faced lizard" and was coined after the original name Platyops turned out to be preoccupied. [3]
Qantassaurus is a genus of basal two-legged, plant-eating elasmarian ornithischian dinosaur that lived in Australia about 125 million years ago, when the continent was still partly south of the Antarctic Circle. It was described by Patricia Vickers-Rich and her husband Tom Rich in 1999 after a find near Inverloch, and named after Qantas, the Australian airline.
Ceratopsia or Ceratopia is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Europe, and Asia, during the Cretaceous Period, although ancestral forms lived earlier, in the Jurassic. The earliest known ceratopsian, Yinlong downsi, lived between 161.2 and 155.7 million years ago. The last ceratopsian species, Triceratops prorsus, became extinct during the Cretaceous–Paleogene extinction event, 66 million years ago.
Lystrosaurus is an extinct genus of herbivorous dicynodont therapsids from the late Permian and Early Triassic epochs. It lived in what is now Antarctica, India, China, Mongolia, European Russia and South Africa. Four to six species are currently recognized, although from the 1930s to 1970s the number of species was thought to be much higher. They ranged in size from that of a small dog to 2.5 meters long.
Serendipaceratops is a genus of herbivorous ornithischian dinosaur, possibly an ankylosaur, from the early Cretaceous Period of Australia. The type species, S. arthurcclarkei, was named in 2003.
Michael James Benton is a British palaeontologist, and professor of vertebrate palaeontology in the School of Earth Sciences at the University of Bristol. His published work has mostly concentrated on the evolution of Triassic reptiles but he has also worked on extinction events and faunal changes in the fossil record.
Timimus is a genus of small coelurosaurian theropod dinosaur from the Early Cretaceous of Australia. It was originally identified as an ornithomimosaur, but now it is thought to be a different kind of theropod, possibly a tyrannosauroid.
Biarmosuchus is an extinct genus of biarmosuchian therapsids that lived around 267 mya during the Middle Permian period. Biarmosuchus was discovered in the Perm region of Russia. The first specimen was found in channel sandstone that was deposited by flood waters originating from the young Ural Mountains.
Fulgurotherium is the name given to a genus of ornithischian dinosaur from the Late Cretaceous (Cenomanian) Griman Creek Formation. It lived in what is now Australia.
Eotitanosuchus is an extinct genus of biarmosuchian therapsids whose fossils were found in the town of Ochyor in Perm Krai, Russia. It lived about 267 million years ago. The only species is Eotitanosuchus olsoni.
Ulemosaurus is an extinct genus of dinocephalian therapsids that lived 265 to 260 million years ago, at Isheevo in Russian Tatarstan. It was a tapinocephalid, a group of bulky herbivores which flourished in the Middle Permian. Ulemosaurus and other tapinocephalians disappeared at the end of the Middle Permian.
Titanophoneus is an extinct genus of carnivorous dinocephalian therapsid from the Middle Permian. It is classified within the family Anteosauridae. The type species is Titanophoneus potens. Remains of Titanophoneus have been found at Isheevo in Russia.
Dvinia is an extinct genus of cynodonts found in the Salarevo Formation of Sokolki on the Northern Dvina River near Kotlas in Arkhangelsk Oblast, Russia. It is the only known member of the family Dviniidae. Its fossil remains date from the Late Permian and were found with Inostrancevia, Scutosaurus and Vivaxosaurus.
Estemmenosuchus is an extinct genus of large, early omnivorous therapsid. It is believed and interpreted to have lived during the middle part of the Middle Permian around 267 million years ago. The two species, E. uralensis and E. mirabilis, are characterised by distinctive horn-like structures, which were probably used for intra-specific display. Both species of Estemmenosuchus are from the Perm region of Russia. Two other estemmenosuchids, Anoplosuchus and Zopherosuchus, are now considered females of the species E. uralensis. There were many complete and incomplete skeletons found together.
Peter Trusler is an Australian artist known for his work on wildlife art, as well as for his scientifically rigorous reconstructions of prehistoric fauna.
Ochyor, alternatively spelled Ocher, is a town and the administrative center of Ochyorsky District in Perm Krai, Russia, located on the Ochyor River, 120 kilometers (75 mi) west of Perm, the administrative center of the krai. Population: 14,238 (2010 Census); 15,563 (2002 Census); 16,352 (1989 Census).
Zygomaturus is an extinct genus of giant marsupial belonging to the family Diprotodontidae which inhabited Australia from the Late Miocene to Late Pleistocene.
Orodus is an extinct genus of cartilaginous fish that lived from the late Pennsylvanian to the early Permian in what is now North America. Growing up to 2 m (7 ft) in length, it was quite large for sharks of its time.
Patricia Arlene Vickers-Rich, also known as Patricia Rich, is an Australian Professor of Palaeontology and Palaeobiology, who researches the environmental changes that have impacted Australia and how this shaped the evolution of Australia’s fauna and flora.
Koinia is an extinct genus of temnospondyl amphibian from the Late Permian of Russia. It is an archegosauroid in the subfamily Melosaurinae. Koinia was named in 1993 with the description of the type species K. silantjevi, based on fossils that were found in the Ocher Assemblage Zone, near the Vym River in the Komi Republic.
Uralosuchus is an extinct genus of temnospondyl amphibian from the Late Permian of Russia, belonging to the group Archegosauroidea. It is a member of the archegosauroidean subfamily Melosaurinae. Fossils have been found in Orenburg Oblast. Uralosuchus was named in 1993 with the description of the type species U. tverdochlebovae.
