Broomistega
''Broomistega'' is an extinct genus of temnospondyl in the family Rhinesuchidae. It is known from one species, ''Broomistega putterilli'', which was renamed in 2000 from ''Lydekkerina putterilli'' Broom 1930. Fossils are known from the Early Triassic ''Lystrosaurus'' Assemblage Zone of the Beaufort Group in the Karoo Basin of present-day South Africa, a region that had been an enclave of Gondwana. Specimens of ''B. putterilli'' were once thought to represent young individuals of another larger rhinesuchid such as ''Uranocentrodon'', but the species is now regarded as a paedomorphic taxon, possessing the features of juvenile rhinesuchids into adulthood. In 2013, a well-preserved skeleton of ''Broomistega'' was discovered alongside the skeleton of the cynodont ''Thrinaxodon'' (a mammal relative) in a cast of a burrow. The individual probably entered the burrow while the cynodont was in a state of aestivation (dormancy), and afterwards a flash flood filled the burrow with sedimen ...

Rhinesuchidae
Rhinesuchidae is a family (biology), family of Tetrapoda, tetrapods that lived primarily in the Permian period. They belonged to the broad group Temnospondyli, a successful and diverse collection of semiaquatic tetrapods which modern amphibians are probably descended from. Rhinesuchids can be differentiated from other temnospondyls by details of their skulls, most notably the interior structure of their otic notches at the back of the skull. They were among the earliest-diverging members of the Stereospondyli, a subgroup of temnospondyls with flat heads and aquatic habits. Although more advanced stereospondyls evolved to reach worldwide distribution in the Triassic period, rhinesuchids primarily lived in the high-latitude environments of Gondwana (what is now South America and Africa) during the Permian, Guadalupian and Permian, Lopingian epochs of the Permian. The taxonomy (biology), taxonomy of this family has been convoluted, with more than twenty species having been named in t ...

Thrinaxodon
''Thrinaxodon'' is an extinct genus of cynodonts which lived in what are now South Africa and Antarctica during the Late Permian - Early Triassic. ''Thrinaxodon'' lived just before, during, and right after the Permian–Triassic mass extinction event. It is known from a single species, ''T. liorhinus''. Similar to other therapsids, ''Thrinaxodon'' adopted a semi-sprawling posture, an intermediary form between the sprawling position of basal tetrapods and the more upright posture present in current mammals.Blob R. 2001. Evolution of hindlimb posture in non-mammalian therapsids: biomechanical tests of paleontological hypotheses. 27(1): 14-38. ''Thrinaxodon'' is prevalent in the fossil record in part because it was one of the few carnivores of its time, and was of a larger size than similar cynodont carnivores. Its survival during the Permian-Triassic extinction event may have been due to its burrowing habits. Description ''Thrinaxodon'' was a small synapsid roughly the size of a ...

Aestivation
Aestivation ( (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state. A study done on '' Otala lactea'', a snail native to parts of Europe and Northern Africa, shows t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaufort Group
The Beaufort Group is the third of the main subdivisions of the Karoo Supergroup in South Africa. It is composed of a lower Adelaide Subgroup and an upper Tarkastad Subgroup. It follows conformably after the Ecca Group and unconformably underlies the Stormberg Group. Based on stratigraphic position, lithostratigraphic and biostratigraphic correlations, palynological analyses, and other means of geological dating, the Beaufort Group rocks are considered to range between Middle Permian ( Wordian) to Early Triassic (Anisian) in age. Background During the period when sedimentation of the Beaufort Group rocks took place, the Ecca sea had retreated to the northeastern Karoo Basin. All sediment deposition at this time took place in a terrestrial, although in a predominantly fluvial or alluvial environment that was seasonally arid. This environment covered a vast area and deposition was influenced by a retroarc foreland basin. This foreland system was caused by crustal uplif ...

Permian Period
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

European Synchrotron Radiation Facility
The European Synchrotron (ESRF) is a joint research facility situated in Grenoble, France, supported by 19 countries (13 member countries: Belgium, Denmark, Finland, France, Germany, Italy, the Netherlands, Norway, Russia, Spain, Sweden, Switzerland, and the UK; and 6 associate countries: Austria, the Czech Republic, Israel, Poland, Portugal and South Africa). Some 10,000 scientists visit this particle accelerator each year, conducting upwards of 2,000 experiments and producing around 1,800 scientific publications. History Inaugurated in September 1994, it has an annual operating budget of around 100 million euros, employs around 700 people and is host to more than 10,000 visiting scientists each year. The ESRF was the world's first third generation synchrotron when it opened for user operation in 1994. In 2009, the ESRF began a major refurbishment programme that, at term, has seen its performances increase by 100-fold. In 2015, the facility built an 8000 m2 extension to ...
