Bohemiclavulus
''Bohemiclavulus'' is a genus of synapsids that was discovered in the Slaný Formation in the Czech Republic. It is only known from a single spinous process fragment. History Antonin Fritsch originally named ''Bohemiclavulus'' with the binomial ''Naosaurus mirabilis''. It was renamed ''Ianthasaurus mirabilis'' in 1895 and was renamed to ''Edaphosaurus mirabilis'' later that year. In 2019, a new genus was created for the species.

Naosaurus
''Edaphosaurus'' (, meaning "pavement lizard" for dense clusters of teeth) is a genus of extinct edaphosaurid synapsids that lived in what is now North America and Europe around 303.4 to 272.5 million years ago, during the Late Carboniferous to Early Permian. American paleontologist Edward Drinker Cope first described ''Edaphosaurus'' in 1882, naming it for the "dental pavement" on both the upper and lower jaws, from the Greek ' ("ground"; also "pavement") and (') ("lizard"). ''Edaphosaurus'' is important as one of the earliest-known, large, plant-eating ( herbivorous), amniote tetrapods (four-legged land-living vertebrates). In addition to the large tooth plates in its jaws, the most characteristic feature of ''Edaphosaurus'' is a sail on its back. A number of other synapsids from the same time period also have tall dorsal sails, most famously the large apex predator ''Dimetrodon''. However, the sail on ''Edaphosaurus'' is different in shape and morphology. The first foss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edaphosaurids
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 herbivore, 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 thermoregulation, thermoregulatory device. Classification The interrelationships of Edaphosauridae was investigated in details by David M. Mazierski and Robert R. Reisz (2010).

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian.

Ianthasaurus
''Ianthasaurus'' is an extinct genus of small edaphosaurids from the Late Carboniferous. Description It is one of the smallest edaphosaurids known, with an skull and a total body length of . ''Ianthasaurus'' lacks many of the spectacular specializations seen in '' Edaphosaurus''. For example, the marginal dentition of ''Ianthasaurus'' is similar to that of insectivorous reptiles, with slender conical teeth which are slightly recurved at the tips, and there is a slight development of a caniniform region. The palatal and mandibular dentition is unspecialized, and there are no batteries of teeth for crushing of plant materials. Also unlike '' Edaphosaurus'', ''Ianthasaurus'' was lightly built and was probably quite agile. The skull was similar to that of '' Haptodus'', a sphenacodontid, though they were distantly related. Discovery It was named by Robert R. Reisz and David Berman in 1986. It was discovered by them in the Upper Pennsylvanian Rock Lake Shale near Garnett, Kansas. ...

Synapsid
Synapsids + (, 'arch') > () "having a fused arch"; synonymous with ''theropsids'' (Greek, "beast-face") are one of the two major groups of animals that evolved from basal amniotes, the other being the sauropsids, the group that includes reptiles and birds. The group includes mammals and every animal more closely related to mammals than to sauropsids. Unlike other amniotes, synapsids have a single temporal fenestra, an opening low in the skull roof behind each eye orbit, leaving a bony arch beneath each; this accounts for their name. The distinctive temporal fenestra developed about 318 million years ago during the Late Carboniferous period, when synapsids and sauropsids diverged, but was subsequently merged with the orbit in early mammals. Traditionally, non-mammalian synapsids were believed to have evolved from reptiles, and therefore described as mammal-like reptiles in classical systematics, and primitive synapsids were also referred to as pelycosaurs, or pelycosaur-gr ...

Slaný
Slaný (; german: Schlan) is a town in Kladno District in the Central Bohemian Region of the Czech Republic. It has about 16,000 inhabitants. The historic town centre is well preserved and is protected by law as an urban monument zone. Administrative parts Villages of Blahotice, Dolín, Lotouš, Kvíc, Kvíček, Netovice, Otruby, Trpoměchy and Želevčice are administrative parts of Slaný. Geography Slaný is located about northwest of Prague, in the Prague Plateau. The Červený Creek flows through the municipal territory from the southwest to the northeast. Its dominant feature is the hill Slánská hora, with above sea level. History The Wenceslaus Hajek's chronicle records Slaný as having been founded in 750, at the site of a salt spring below the Slánská hora Hill (''slaný'' is a Czech word for "salty"). The first written mention of Slaný is from 1262. The town grew as a result of its location on the trade route between Prague and Saxony. The Benedictines establi ...

Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Spinous Process
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

List Of Pelycosaurs
This list of pelycosaurs is an attempt to create a comprehensive listing of all genera that have ever been included in the synapsida excluding therapsida and purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered pelycosaurs. The list currently contains 83 generic names. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms.
