Spalacotheriidae
Spalacotheriidae is a family of extinct mammals belonging to the paraphyletic group ' Symmetrodonta'. They lasted from the Early Cretaceous to the Campanian in North America, Europe, Asia and North Africa. Spalacotheriids are characterised by having molar teeth with three molar cusps sitting at acute angles to one another.Martin, T., 2018. 6. Mesozoic mammals—early mammalian diversity and ecomorphological adaptations. In Mammalian evolution, diversity and systematics (pp. 199-300). De Gruyter. The shape of their teeth as well as their long lower jaw indicate a carnivorous/insectivorous diet. A sub-group of Spalacotheriidae, the spalacolestines, lack a Meckelian groove in the jaw, indicating that they had a modern ear anatomy.

Akidolestes
''Akidolestes'' is an extinct genus of mammals of the family Spalacotheriidae, a group of mammals related to therians (the subclass containing marsupials and placentals). The genus name, ''Akidolestes'', is derived from ''akido'', Greek for point, and ''lestes'', Greek for thief. Akido- refers to the pointed snout and -lestes is a common suffix for fossil mammals. The specific epithet, ''cifelli'', is in honor of Richard L. Cifelli, a prominent researcher in prehistoric mammals. An ''Akidolestes'' fossil preserved with a complete post-cranium and a partial skull was discovered in the Yixian Formation of Liaoning, China. The holotype of ''Akidolestes cifellii'', reserved in the Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, has a complete skeleton with a partial skull and dentition. It displays characteristics of monotremes but appears to be more related to modern therian mammals. Although it had some features similar to monotremes in the lumbar ...

Symmetrolestes
''Symmetrolestes'' is an extinct genus of small spalacotheriid mammal from the Early Cretaceous period of Japan. The genus contains one species known as ''S. parvus'', the type fossil (which is only fossil known) is from fluvial deposits located in the Dinosaur Quarry in the Kitadani Formation, near the city of Katsuyama, Fukui, Katsuyama which lies alongside valley of the Sugiyamagawa River. It was described by Tsubamoto and Rougier in 2004. The holotype is kept at the National Science Museum, Tokyo, Japan. Description The type specimen (NSM PV 20562, holotype) is known from a fragmentary right jaw with the first incisor and five postcanine teeth preserved. ''Symmetrolestes'' is more derived than zhangheotheriidae, zhangheotheriids as it had acute−angled molariform teeth with completely developed shearing surfaces, taller crowns on its teeth and more complete cingulidae, cingulids. It differs from other spalacotheriids due to the fact it had fewer molariform teeth, a higher num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spalacotherium
''Spalacotherium'' is a genus of extinct mammal from the Early Cretaceous of Europe. The type species ''Spalacotherium tricuspidens'' was originally named by Richard Owen in 1854, and its material includes maxillary and dentary fragments and many teeth from the Berriasian Lulworth Formation of southern England. Referred species include ''S. taylori'', ''S. evansae'' and ''S. hookeri'' also from the Lulworth deposits, and ''S. henkeli'' from Barremian deposits of Galve, Spain. The Lulworth taxon ''Peralestes longirostris'', named by Owen in 1871, is a junior synonym of the type species ''S. tricuspidens''. ''Spalacotherium'' is the namesake taxon of the family Spalacotheriidae, which is an extinct clade within Trechnotheria that may be closely related to the Gondwana Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Aust ...

Symmetrodonta
Symmetrodonta is a group of Mesozoic mammals and mammal-like synapsids characterized by the triangular aspect of the molars when viewed from above, and the absence of a well-developed talonid. The traditional group of 'symmetrodonts' ranges in age from the latest Triassic to the Late Cretaceous, but most research in the last 20-30 years has concluded that they are not a true taxonomic group, but include several unrelated branches of the mammal tree. Despite this, the name is still used informally by some researchers for convenience, usually restricted to the spalacotheriids and zhangheotheriids. Martin, T., 2018. 6. Mesozoic mammals—early mammalian diversity and ecomorphological adaptations. In Mammalian evolution, diversity and systematics (pp. 199-300). De Gruyter. There are some symmetrodonts with acutely-triangulated molar cusps (“acute-angled symmetrodonts”) that seem to form a true monophyletic group, and lasted from the Early Cretaceous to the Campanian, although ...
