Taeniolabidoidea
Taeniolabidoidea is a group of extinct mammals known from 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.L.

Multituberculata
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Late Cretaceous and Paleocene. They eventually declined from the mid Paleocene onwards, disappearing from the known fossil record in the late Eocene. They are the most diverse order of Mesozoic mammals with more than 200 species known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and MonotremataAgustí-Antón 2002, pp 3-4—but usually as closer to Theria than to monotremes. They are considered to be clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kogaionidae
Kogaionidae is a family of fossil mammals within the extinct order Multituberculata. Representatives are known from the Upper Cretaceous and the Paleocene of Europe. Having started as island endemics on Hateg Island during the Upper Cretaceous, where they were in fact the dominant mammal group and diverged into rather unique ecological niches, they expanded across Europe in the Paleocene, where they briefly became a major component of its mammal fauna before their extinction.First mammal species identified from the Upper Cretaceous of the Rusca Montana Basin (Transylvania, Romania) Article in Comptes Rendus Palevol https://dx.doi.org/10.1016/j.crpv.2016.04.002 · June 2016 They are considered to be basal members of Cimolodonta.

Taeniolabis Taoensis
''Taeniolabis'' ("banded incisor") is a genus of extinct multituberculate mammal from the Paleocene of North America. Description It is the largest known member of the extinct order Multituberculata, as well as the largest non-therian mammal: ''T. taoensis'', a species known from Danian deposits in the Denver Formation of Colorado, possibly exceeds 100 kg. Taxonomy It is within the suborder of Cimolodonta and is a member of the superfamily Taeniolabidoidea. The genus was named by Edward Drinker Cope in 1882. Species have also been placed with the genera '' Catopsalis'' and ''Polymastodon''. The species ''Taeniolabis lamberti'' was named by N.B. Simmons in 1987. It has been found in the Puercan (Paleocene)-age Tullock Formation of Montana. It is not quite as large as ''T. taoensis'', but still a hefty size for a multituberculate. The species ''Taeniolabis taoensis'' was named by Cope E.D. in 1882. It is also known as ''Catopsalis pollux'' (Cope, 1882); ''Polymastod ...

Taeniolabididae
Taeniolabididae is one of the two multituberculate clades within Taeniolabidoidea. Originally basically synonymous with Taeniolabidoidea, it has more recently been found to be a specific clade including ''Kimbetopsalis'', '' Taeniolabis'' and some former members of the ''Catopsalis'' wastebasket taxon, as opposed to Lambdopsalidae, which includes most other genera outside of ''Valenopsalis'' and possibly '' Bubodens'', both of which more basal taxa. Unlike the longer spanning lambdopsalids, taeniolabibids remained exclusive to the Puercan of North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car ... and did not live longer nor spread into Asia, nor did they develop some of the more sophisticated dental speciations to cope with grass.

Lambdopsalidae
Lambdopsalidae is a family of extinct multituberculate mammals from the Late Paleocene of Asia. They are part of Taeniolabidoidea, a clade otherwise present in the Early Paleocene (and possibly the Late Cretaceous) of North America; lambdopsalids, therefore, probably evolved from a single radiation that spread into Asia from North America in the mid-Paleocene or earlier. They are represented by the genus ''Lambdopsalis'', ''Sphenopsalis'' and ''Prionessus''. Though they haven't become as large as ''Taeniolabis'', lambdopsalids were still large by multituberculate standards, the largest species weighting around 30 kg. They are notable for their unique dental speciations such as hypsodonty, which seem to imply speciations towards grazing. ''Lambdopsalis'' is notable for offering direct evidence of hair and enamel and tooth prism patterns among multituberculates. Lambdopsalids lived in the final stages of the Paleocene, disappearing around the PETM. They co-existed with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambdopsalis
''Lambdopsalis bulla'' is an extinct multituberculate mammal from the Late Paleocene of China and Mongolia. It is placed within the suborder Cimolodonta and is a member of the superfamily Taeniolabidoidea. Fossil remains have been found in the Late Paleocene Nomogen and Khashat Formations in Nao-mugen and Bayn Ulan of China and Mongolia. Hair and fur fossilize very infrequently, if at all. This genus of burrowing multituberculate mammals provides one of the earliest unequivocal examples of mammal fur (Lower Cretaceous fossils of ''Eomaia, Volaticotherium'' and ''Castorocauda'' with the fur preserved still attached are currently the oldest). Indirect evidence suggest that hair first appeared on non-mammalian therapsids ( Therapsida), back in the Triassic or even earlier. This is inferred from small hollows on the bone of the snout similar to holes in the skulls of cats which provide space for concentrations of nerves and blood vessels that innervate prominent whiskers (specia ...

Sphenopsalis
''Sphenopsalis'' is a genus of extinct mammal from the Paleocene of Central Asia. It was a member of the extinct order Multituberculata, and lies within the suborder Cimolodonta and the superfamily Taeniolabidoidea. The genus was named by William Diller Matthew, W. Granger and George Gaylord Simpson in 1928. The one known species, ''Sphenopsalis nobilis'', was also named by Matthew, Granger and Simpson in 1928. It was found in the Late Paleocene Nomogen and Khashat Formations of Mongolia and China. The American Museum of Natural History in New York City has a specimen in its collection.

Valenopsalis
''Valenopsalis'' is an extinct mammal from the Paleocene of North America (more specifically, Puercan-aged deposits in Wyoming, Montana and Saskatchewan. Originally referred to the genus '' Catopsalis'' (''C. joyneri''), it has more recently been moved to its own genus as the former was understood to be a wastebasket taxon. It is currently considered to be the most basal representative of Taeniolabidoidea Taeniolabidoidea is a group of extinct mammals known from North America and Asia.

Catopsalis
''Catopsalis'' is a genus of extinct mammal from the Paleocene of North America. This animal was a relatively large member of the extinct order of Multituberculata. Most Multituberculates were much smaller. At one time, the genus was also formally reported from the upper Cretaceous of Mongolia. However, that material was subsequently referred to the genera of '' Djadochtatherium'' and ''Catopsbaatar''. ''Catopsalis'' is within the suborder of Cimolodonta and a member of the superfamily Taeniolabidoidea. Recent research suggests that "Catopsalis" is actually a paraphyletic assemblage, and one species, ''C. joyneri'', has been moved to its own genus, ''Valenopsalis''.Thomas E. Williamson, Stephen L.

Yubaatar
''Yubaatar'' is a genus of multituberculate, an extinct order of rodent-like mammals, which lived in what is now China during the Late Cretaceous. The first specimen was discovered in the Qiupa Formation of Luanchuan County, in the Henan Province. The specimen consists of a partial skeleton with a nearly complete skull, and was made the holotype of the new genus and species ''Yubaartar zhongyuanensis'' by the Chinese palaeontologist Li Xu and colleagues in 2015. The generic name consists of the word ''Yu'', which is the pinyin spelling of the Chinese character for the Henan Province, and the Mongolian word ''baatar'', which means "hero", a word commonly used as suffix in the names of Asian multituberculates. The specific name comes from Zhongyuan, an ancient name for the geographic area of the province. ''Yubaatar'' is the first known and southernmost Late Cretaceous multituberculate outside of the Mongolian plateau (most multituberculate specimens mainly consist only of teeth ...
