Theriognathus Laticeps
''Theriognathus'' (from Greek therion: beast, mammal, Greek, gnathos, “jaw,” +us, pronounced THEH-ree-OG-nah-thuss) is an extinct genus of therocephalian therapsid belonging to the family Whaitsiidae, known from fossils from South Africa, Zambia, and Tanzania. ''Theriognathus'' has been dated as existing during the Late Permian. Although ''Theriognathus'' means mammal jaw, the lower jaw is actually made up of several bones as seen in modern reptiles, in contrast to mammals. ''Theriognathus'' displayed many different reptilian and mammalian characteristics. For example, ''Theriognathus'' had canine teeth like mammals, and a secondary palate, multiple bones in the mandible, and a typical reptilian jaw joint, all characteristics of reptiles. It is speculated that ''Theriognathus'' was either carnivorous or omnivorous based on its teeth, and was suited to hunting small prey in undergrowth. This synapsid adopted a sleek profile of a mammalian predator, with a narrow snout and aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ictidochampsa
''Ictidochampsa'' is an extinct genus of therocephalian therapsids from the Late Permian of South Africa. The type species ''Ictidochampsa platyceps'' was named by South African paleontologist Robert Broom Robert Broom FRS FRSE (30 November 1866 6 April 1951) was a British- South African doctor and palaeontologist. He qualified as a medical practitioner in 1895 and received his DSc in 1905 from the University of Glasgow. From 1903 to 1910, he ... in 1948 from the ''Dicynodon'' Assemblage Zone.

Megawhaitsia
''Megawhaitsia'' is an extinct genus of large therocephalian therapsids who lived during the Late Permian in what is now Eastern Europe. The only known species is ''M. patrichae'', described in 2008 from several fossils discovered in various oblasts of European Russia. The fossils are representative of a large animal whose skull size is estimated to be 40–50 cm long. The most notable feature of ''Megawhaitsia'' is that it has a maxilla with canals directly connected to the tooth root of the canines. Based on the characteristics present in the related genus ''Euchambersia'', Russian paleontologist Mikhail Ivakhnenko raises the possibility that the animal may have had a venom gland. If it is true, then it would then be one of the oldest tetrapods known to have this attribute. However, subsequent studies challenge this proposition, which therefore remains uncertain. The imposing size of ''Megawhaitsia'' and its position as an apex predator could be linked to the disappearan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Therapsid
Therapsida is a major group of eupelycosaurian synapsids that includes mammals, their ancestors and relatives. Many of the traits today seen as unique to mammals had their origin within early therapsids, including limbs that were oriented more underneath the body, as opposed to the sprawling posture of many reptiles and salamanders. Therapsids evolved from "pelycosaurs", specifically within the Sphenacodontia, more than 279.5 million years ago. They replaced the "pelycosaurs" as the dominant large land animals in the Middle Permian through to the Early Triassic. In the aftermath of the Permian–Triassic extinction event, therapsids declined in relative importance to the rapidly diversifying reptiles during the Middle Triassic. The therapsids include the cynodonts, the group that gave rise to mammals ( Mammaliaformes) in the Late Triassic, around 225 million years ago. Of the non-mammalian therapsids, only cynodonts survived beyond the end of the Triassic, with the only other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian First Appearances
The Permian ( ) is a geologic period and 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 251.9 Mya. It is the 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 region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the 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 drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
