Microcosmodon Conus
''Microcosmodon'' is a mammal genus from the Paleocene of North America. It was a member of the extinct order Multituberculata, and lies within the suborder Cimolodonta and family Microcosmodontidae. The genus ''Microcosmodon'' was named by G.L. Jepsen in 1930. Species The species ''Microcosmodon arcuatus'' was named by P.A. Johnston and R.C. Fox in 1984. Fossil remains have been found in the Puercan (Paleocene)-age Stratum, strata Rav W-1 of Saskatchewan, Canada. The holotype is in the University of Alberta collection. When alive, the creature weighed about the same as a well-fed mouse (about 30 g). The type species ''Microcosmodon conus'' was named by G.L. Jepsen in 1930. Remains have been found in the Tiffanian (Paleocene)-age strata of the Polecat Bench Formation of Wyoming (United States) and Saskatchewan, Canada. This species would have weighed around 15 g. The species ''Microcosmodon harleyi'' was named by A. Weil in 1998. Remains have been found in the Puercan (Paleoce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

University Of Alberta
The University of Alberta (also known as U of A or UAlberta, ) is a public research university located in Edmonton, Alberta, Canada. It was founded in 1908 by Alexander Cameron Rutherford, the first premier of Alberta, and Henry Marshall Tory, the university's first president. It was enabled through the ''Post-secondary Learning Act.'' The university is considered a "comprehensive academic and research university" (CARU), which means that it offers a range of academic and professional programs that generally lead to undergraduate and graduate level credentials. The university comprises four campuses in Edmonton, an Augustana Campus in Camrose, Alberta, Camrose, and a staff centre in downtown Calgary. The original north campus consists of 150 buildings covering 50 city blocks on the south rim of the North Saskatchewan River valley parks system, North Saskatchewan River valley, across and west from downtown Edmonton. About 37,000 students from Canada and 150 other countries partici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene Genus Extinctions
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Taeniolabidoidea
Taeniolabidoidea is a group of extinct mammals known whose fossils can be found in North America and Asia. They were the largest members of the extinct order Multituberculata, as well as the largest non-therian mammals. '' Lambdopsalis'' even provides direct fossil evidence of mammalian fur in a fairly good state of preservation for a 60-million-year-old animal. Some of these animals were large for their time; '' Taeniolabis taoensis'' is the largest known multituberculate and though smaller, ''Yubaatar'' is the largest known Mesozoic Asian multituberculate. ''T. taoensis'' averaged a body mass of . The group was initially established as a suborder, before being assigned the rank of a superfamily by McKenna and Bell in 1997. Two families are recognised: the primarily North American Taeniolabididae, composed of ''Taeniolabis'' and '' Kimbetopsalis'', and the exclusively Asian Lambdopsalidae, composed of '' Lambdopsalis'', '' Sphenopsalis'' and '' Prionessus'', with '' Valenop ...

Eucosmodontidae
Eucosmodontidae is a poorly preserved family of fossil mammals within the extinct order Multituberculata. Representatives are known from strata dating from the Upper Cretaceous through the Lower Eocene of North America, as well as the Paleocene to Eocene of Europe. The family is part of the suborder of Cimolodonta. They might be related with the Djadochtatherioidea but without further finds, this remains unclear. Other than a partial snout, fossil evidence is limited to teeth. A 2021 study vindicates this relationship.Smith, Thierry; Codrea, Vlad A.; Devillet, Ghéreint; Solomon, Alexandru A. (2021-09-24).

ISSN 1064-7554. S2CID 244194193. The taxonomic name Eucosmodontidae was given by Jepsen in 1940. Some authors interpret this version of Eucosmodontidae and Microcosmodontidae as being ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...
