Description

Thuringothyris is known from the holotype MNG  7729, articulated well-preserved skull and partial postcranial skeleton, and from the referred specimens MNG 10652, poorly preserved skull and partial vertebral column, MNG 10647, disarticulated cranial and postcranial remains of at least four individuals, MNG 10183, slightly crushed skull and partial postcranial skeleton and MNG 11191, poorly preserved skull and partial limbs. All specimens were collected from the Tambach-Sandstein Member, the uppermost part of the Tambach Formation, dating to the Artinskian stage of the Late Cisuralian Series (or alternatively upper Rotliegend), about 284–279.5 million years ago. They were found in the Bromacker Quarry, the middle part of the Thuringian Forest, near the small town of Tambach-Dietharz. [2]

Thuringothyris was originally thought to be protorothyridid. A redescription of all known Thuringothyris specimens by Johannes Müller, David S. Berman, Amy C. Henrici, Thomas Martens and Stuart S. Sumida in 2006 suggested that it is a sister taxon of Captorhinidae. [2] A noval phylogenic study of primitive reptile relationships by Müller & Reisz in 2006 recovered Thuringothyris as a sister taxon of the Captorhinidae. [3] The same results were obtained in later phylogenic analyses. [4] [5]

Etymology

Thuringothyris was first named by Jürgen A. Boy and Thomas Martens in 1991 and the type species is Thuringothyris mahlendorffae. The generic name is named after its finding place Thuringia. The specific name honors Ursula R. Mahlendorf. [1]

Captorhinidae is one of the earliest and most basal reptile families, all members of which are extinct.

<i>Seymouria</i> genus of reptile-like amphibians

Seymouria is an extinct genus of seymouriamorph from the Early Permian of North America and Europe. Although they were amphibians, Seymouria were well-adapted to life on land, with many reptilian features—so many, in fact, that Seymouria was first thought to be a primitive reptile. It is primarily known from two species, Seymouria baylorensis and Seymouria sanjuanensis. The type species, S. baylorensis, is more robust and specialized, though its fossils have only been found in Texas. On the other hand, Seymouria sanjuanensis is more abundant and widespread. This smaller species is known from multiple well-preserved fossils, including a block of six skeletons found in the Cutler Formation of New Mexico, and a pair of fully grown skeletons from the Tambach Formation of Germany, which were fossilized lying next to each other.

<i>Labidosaurikos</i> genus of reptiles (fossil)

Labidosaurikos is a genus of extinct captorhinid anapsid reptile that lived around 279 to 272 million years ago during Kungurian age of the lower Permian. The American Paleontologist John Willis Stovall first described Labidosaurikos in 1950, naming it "Labidosaurus like" for the striking similarity of the holotype skull of his specimen to the cranial anatomy of another captorhinid Labidosaurus hamatus. Labidosaurus or generally called “lipped lizard” is another genus of the family Captorhinidae whose name is derived from the Greek “forceps lizard” based on τσιμπίδα and σαυρος ("lizard")

Romeriida is a clade of reptiles that consists of diapsids and the extinct protorothyridid genus Paleothyris, if not the entire family Protorothyrididae. It is phylogenetically defined by Laurin & Reisz (1995) as the last common ancestor of Paleothyris and diapsids, and all its descendants. It is named after Alfred Romer, a prominent vertebrate paleontologist of the twentieth century.

Tambachia is an extinct genus of dissorophoid temnospondyl within the family Trematopidae. It is known from the Early Permian Tambach Formation near the town of Tambach-Dietharz in Thuringia, Germany. Tambachia is the first trematopid to have been discovered outside the United States.

Ostodolepidae family of the first four-limbed vertebrates and their descendants

Ostodolepidae, also spelled Ostodolepididae, is an extinct family of Early Permian microsaurs. They are unique among microsaurs in that they were large, reaching lengths of up to 2 feet (61 cm), terrestrial, and presumably fossorial. Ostodolepid remains have been found from Early Permian beds in Texas, Oklahoma, and Germany.

Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2011.

Georgenthalia is an extinct genus of dissorophoid temnospondyl from the Lower Permian. It is an amphibamid which lived in what is now the Thuringian Forest of central Germany. It is known from the holotype MNG 11135, a small, complete skull. It was found in the Bromacker locality of the Tambach Formation. It was first named by Jason S. Anderson, Amy C. Henrici, Stuart S. Sumida, Thomas Martens and David S. Berman in 2008 and the type species is Georgenthalia clavinasica.

Tambaroter is an extinct genus of ostodolepid microsaur from the Early Permian of Germany. The type species T. carrolli was named in 2011. Tambaroter is known from a single skull found in the Tambach Formation, which is the lowermost unit of the Upper Rotliegend. It is the only vertebrate that has been found outside the Bromacker Quarry, the most productive locality of the formation. It is also the first ostodolepid known from outside North America.
