Parotosuchus
''Parotosuchus'' is an extinct genus of capitosaurian temnospondyl amphibians within the family Mastodonsauridae. Fossils are known from the Early Triassic of Europe, Africa, Australia, and Antarctica. It was about long and likely lived in aquatic environments such as lakes and rivers. ''Parotosuchus'' was covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water. ''Parotosuchus'' was originally named ''Parotosaurus''. However, the name ''Parotosaurus'' was preoccupied by a genus of skinks, and in 1968 the name ''Parotosuchus'' was proposed as a replacement. The name ''Archotosaurus'' was also proposed as a replacement name in 1976, although the author who proposed this was unaware that ''Parotosuchus'' was already in use. Because the name ''Parotosuchus'' was erected earlier than ''Archotosaurus'', it has priority. References Further reading *Parotosuchus (Temnospondyli: Mastodonsauridae) from the Tr ...

Mastodonsauridae
Mastodonsauridae is a family of capitosauroid temnospondyls. Fossils belonging to this family have been found in North America, Greenland, Europe, Asia, and Australia. The family Capitosauridae is synonymous with Mastodonsauridae. Description Size Mastodonsaurids were generally large amphibians, with some length estimates ranging from 3 to 6 meters. Some genera, like '' Mastodonsaurus'' and '' Cyclotosaurus'' were specially large, reaching at least 4 meters or more. Other genera like '' Parotosuchus'' and ''Paracyclotosaurus'' only reached 2 meters or more in length, but it's still pretty large compared to modern-day amphibians. Distinguishing features Some mastodonsaurids including ''Parotosuchus'' were covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water. Another peculiar mastodonsaurid is ''Sclerothorax'', with unusual features including its elongated neural spines. The neural spines are talles ...

Capitosauria
Capitosauria is an extinct group of large temnospondyl amphibians with simplified stereospondyl vertebrae. Mainly living as piscivores in lakes and rivers, the Capitosauria and its sister taxon Trematosauria were the only major labyrinthodonts that existed during the Mesozoic in ecological niches broadly similar to those of modern crocodiles, and some grew to very large sizes. At 6 meters in length, the Mid-Triassic '' Mastodonsaurus giganteus'' is not only thought to have been the largest capitosaur, but possibly also the largest amphibian to have lived. The latest known remains are from the Rhaetian of Germany and are referred to '' Cyclotosaurus''. Capitosauria was first named by Schoch and Milner (2000) and further described by Yates and Warren (2000), who assigned '' Lydekkerina'' and Mastodonsauroidea to it. It was described by Damiani (2001) under the name Mastodonsauroidea. In their phylogenetic analysis of temnospondyls, Ruta ''et al.'' (2007) placed ''Lydekkerina'' ...

Triassic Temnospondyls Of Europe
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Extinct Animals Of Antarctica
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prehistoric Amphibians Of Australia
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Vertebrate Paleontology
The ''Journal of Vertebrate Paleontology'' is a bimonthly peer-reviewed scientific journal that was established in 1980 by Jiri Zidek (University of Oklahoma). It covers all aspects of vertebrate paleontology, including vertebrate origins, evolution, functional morphology, taxonomy, biostratigraphy, paleoecology, paleobiogeography, and paleoanthropology. The journal is published by Taylor & Francis on behalf of the Society of Vertebrate Paleontology.
