Triassic
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 arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Trematosuchus
''Trematosuchus'' is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae from South Africa. It was first named by Haughton in 1915 as '' Trematosaurus sobeyi''.

Trematosaurus
''Trematosaurus'' is an extinct genus of trematosaurid temnospondyl amphibian found in Germany and Russia. It was first named by Hermann Burmeister in 1849 and the type species is ''Trematosaurus brauni''. History of study ''Trematosaurus'' was one of the first temnospondyls to be described. The type locality, called Merkel's Quarry, is in east-central Germany at Bernburg an der Saale within the Bausandstein ( Olenekian) and was collected for several decades from the 1840s into the early 20th century, producing extensive cranial remains, although the majority of these are preserved as internal molds (steinkerns) or natural molds. The name ''Trematosaurus'' was in fact coined in 1842 by Carl von Braun, a frequent collector who used the Greek suffix ''trema'' ('hole') in reference to the pineal foramen to form the generic epithet, but as he provided no formal description, the name was not considered valid until the work of Burmeister, who named the type species after Braun. ...

Trematosaurinae
Trematosaurinae is a subfamily of temnospondyl amphibians within the family Trematosauridae. Like all trematosaurids, they were marine piscivores, resembling crocodiles in their general build. Unlike the long, almost gharial-like snouts of the Lonchorhynchinae, the Trematosaurinae had more "normal" crocodile-like skulls.Damani, Ross (2004). “Cranial anatomy and relationships of Microposaurus casei, a temnospondyl from the MiddleTriassic of South Africa”.

Trematosauridae
Trematosauridae are a family of large marine temnospondyl amphibians with many members. They first appeared during the Induan age of the Early Triassic, and existed until around the Carnian stage of the Late Triassic, although by then they were very rare. By the Middle Triassic they had become widespread throughout Laurasia and Gondwana with fossils being found in Europe, Asia, Madagascar, and Australia. They are one of the most derived families of the Trematosauroidea superfamily in that they are the only family that have fully marine lifestyles. Long, slender snouts that are characteristic of the trematosaurids, with some members having rostrums resembling those of modern-day gavials. Traditionally, two subfamilies within Trematosauridae can be identified, the relatively short-nosed Trematosaurinae and the long-nosed Lonchorhynchinae. A third subfamily, Tertreminae, was named in 2000 and includes broad-snouted forms like '' Tirraturhinus''. Below is a cladogram from St ...
