Haptodus Baylei
''Haptodus'' is an extinct genus of basal (phylogenetics), basal sphenacodont, member of the clade that includes therapsids and hence, mammals. It was at least in length. It lived in present-day France during the Early Permian. It was a medium-sized predator, feeding on insects and small vertebrates. Discovery and history ''Haptodus baylei'' ''Haptodus baylei'', the type species of ''Haptodus'', is known only from a single, badly preserved specimen hosted in the Muséum National d'Histoire Naturelle of Paris. It was collected at Les Télots, near Autun of France, from a terrestrial horizon dating to the Asselian stage of the Cisuralian Series (stratigraphy), series, about 299-296.4 million years ago, million years old. The taxonomy of many pelycosaurs was revised in details by Alfred Sherwood Romer & Llewellyn Price (1940). They synonymized many genera, including ''Callibrachion'' (from Margenne near Autun, France), ''Datheosaurus'' (from Nowa Ruda of Poland), ''Palaeohatte ...

Pantelosaurus
''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 hapto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeohatteria
''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).

Datheosaurus
''Datheosaurus'' is an extinct genus of caseasaur. It was at least in length. It lived during the Latest Carboniferous to Early Permian in Poland. Discovery and history It was originally described in 1905 on a basis of a specimen from late Carboniferous deposits in Poland. It was later considered a synonym of ''Haptodus'' by several authors, but subsequent examination has found it be a caseid rather a sphenacodont. This was confirmed by cladistic analysis, which recovered ''Datheosaurus'' as a basal caseid Caseidae are an extinct family of basal synapsids that lived from the Late Carboniferous to Middle Permian between about 300 and 265 million years ago.

Callibrachion
''Callibrachion'' is an extinct genus of caseid synapsids that lived in east-central France during the Lower Permian (Asselian). The holotype and only known specimen ( MNHN.F.AUT490) is represented by an almost complete postcranial skeleton associated with skull fragments discovered at the end of the 19th century in the Permian Autun basin in Saône-et-Loire department, in the Bourgogne-Franche-Comté region. It belongs to an immature individual measuring less than 1.50 m in length. ''Callibrachion'' was long considered a junior synonym of the genus ''Haptodus'' and classified among the sphenacodontid pelycosaurs. In 2015, a new study found that ''Callibrachion'' was a different animal from ''Haptodus'' and that it was a caseasaur rather than a sphenacodontid. This was confirmed in 2016 by a cladistic analysis which recovered ''Callibrachion'' as a basal caseid. ''Callibrachions sharp teeth and unenlarged ribcage indicate that this animal was likely faunivorous. Description ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelycosaur
Pelycosaur ( ) is an older term for basal or primitive Late Paleozoic synapsids, excluding the therapsids and their descendants. Previously, the term ''mammal-like reptile'' had been used, and pelycosaur was considered an order, but this is now thought to be incorrect, and seen as outdated. Because it excludes the advanced synapsid group Therapsida, the term is paraphyletic and contrary to modern formal naming practice. Thus the name ''pelycosaurs'', similar to the term ''mammal-like reptiles'', had fallen out of favor among scientists by the 21st century, and is only used informally, if at all, in the modern scientific literature. The terms stem mammals, protomammals, and basal or primitive synapsids are used where needed, instead. Etymology The term ''pelycosaur'' has been fairly well abandoned by paleontologists because it no longer matches the features that distinguish a clade. The modern word was created from Greek meaning 'wooden bowl' or 'axe' and meaning 'lizar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Million Years Ago
The abbreviation Myr, "million years", is a unit of a quantity of (i.e. ) years, or 31.556926 teraseconds. Usage Myr (million years) is in common use in fields such as Earth science and cosmology. Myr is also used with Mya (million years ago). Together they make a reference system, one to a quantity, the other to a particular place in a year numbering system that is ''time before the present''. Myr is deprecated in geology, but in astronomy ''Myr'' is standard. Where "myr" ''is'' seen in geology it is usually "Myr" (a unit of mega-years). In astronomy it is usually "Myr" (Million years). Debate In geology a debate remains open concerning the use of ''Myr'' (duration) plus ''Ma'' (million years ago) versus using only the term ''Ma''. In either case the term '' Ma'' is used in geology literature conforming to ISO 31-1 (now ISO 80000-3) and NIST 811 recommended practices. Traditional style geology literature is written The "ago" is implied, so that any such year number "X Ma" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
