Sphenacodontia
Sphenacodontia is a stem-based clade of derived synapsids. It was defined by Amson and Laurin (2011) as "the largest clade that includes ''Haptodus baylei'', ''Haptodus garnettensis'' and '' Sphenacodon ferox'', but not ''Edaphosaurus pogonias''". They first appear during the Late Pennsylvanian (Upper Carboniferous) epoch. From the end of the Carboniferous to the end of the Permian, most of them remained large, with only some secondarily becoming small in size. Basal Sphenacodontia constitute a transitional evolutionary series from early pelycosaurs to ancestral therapsids (which in turn were the ancestors of more advanced forms and finally the mammals). One might say that the sphenacodontians are proto-therapsids (even though there is almost a 30-million-years gap between the separation of the ancestors of therapsids from other sphenacodontians and the first appearance of therapsids in the fossil record). Characteristics The defining characteristics include a thickening of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palaeohatteria Longicaudata
''Palaeohatteria'' is an extinct genus of basal sphenacodonts known from the Early Permian period (Sakmarian stage) of Saxony, Germany. It contains a single species, ''Palaeohatteria longicaudata''. Discovery ''Palaeohatteria'' is based on very young individuals including skulls and partial postcranial skeletons. All specimens were collected at Niederhäslich locality, in Dresden, from the Niederhäslich Limestone Member of the Niederhäslich Formation, Rotliegend Group (Döhlen Basin), dating to the Sakmarian stage of the Cisuralian series, about 295.0 -290.1 million years old. Description ''Palaeohatteria'' was a fairly small synapsid, up to 60 cm in length and with a mass of about 3 kg. The affinities of ''Palaeohatteria'' to the pelycosaur were first described in details by Alfred Sherwood Romer & Llewellyn Price (1940). They revised the taxonomy of pelycosaurs and synonymized ''Palaeohatteria'' (alongside with ''Pantelosaurus'' and others) with ''Haptodus' ...

Pantelosaurus Saxonicus
''Pantelosaurus'' (meaning "complete lizard") is an extinct genus of basal sphenacodonts known from the Early Permian period (Asselian stage) of Saxony, Germany. It contains a single species, ''Pantelosaurus saxonicus''. Discovery ''Pantelosaurus'' is known from about 6 individuals including skulls and partial postcranial skeletons. All specimens were collected at Königin-Carola-Schacht locality, in Dresden, from the uppermost part of the Döhlen Formation, lower Rotliegend Group (Döhlen Basin), dating to the Asselian stage of the Cisuralian series, about 299–296.4 million years old. Classification ''Pantelosaurus'' was first described by von Huene (1925) as a pelycosaur. In 1940, Alfred Sherwood Romer and Llewellyn Price revised the taxonomy of pelycosaurs and synonymized ''Pantelosaurus'' with ''Haptodus'', creating the new combination ''Haptodus saxonicus''. After describing a new species of ''Haptodus'' in 1977, Currie (1979) synonymized all European haptodontine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...

Edaphosauridae
Edaphosauridae is a family of mostly large (up to 3 meters or more) Late Carboniferous to Early Permian synapsids. Edaphosaur fossils are so far known only from North America and Europe. Characteristics They were the earliest known herbivorous amniotes and, along with the Diadectidae, the earliest known herbivorous tetrapods. The head is small in relation to the bulky body, and there is a tall sail along the back, which may have functioned as a thermoregulatory device. Classification The interrelationships of Edaphosauridae was investigated in details by David M. Mazierski and Robert R. Reisz (2010).

Haptodus Garnettensis
''"Haptodus" garnettensis'' is an extinct species of basal sphenacodont from the Late Carboniferous ( Pennsylvanian) of Kansas, USA. Taxonomy The holotype of ''"Haptodus" garnettensis'' is RM 14156, a partially articulated skeleton (cranial and postcranial) of immature individual. More than 16 well-preserved specimen of various ontological states were referred to this species. All specimens came from the Garnett Quarry, located in the Anderson County of Kansas. They were collected from the Rock Lake Member of the Stanton Formation (Lansing Group), dating to the late Kasimovian stage of the late Pennsylvanian series, about 304 million years old. Laurin (1993, 1994) suggested that ''Haptodus garnettensis'' would have to be renamed because he saw ''Haptodus baylei'' as a possible ''nomen dubium''. In his dissertation revising taxa assigned to ''Haptodus'', Spindler (2015) proposed that ''"Haptodus" garnettensis'' is not congeneric with the ''Haptodus'' type specie ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
