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.

Catopsbaatar
''Catopsbaatar'' is a genus of multituberculate, an extinct order of rodent-like mammals. It lived in what is now Mongolia during the late Campanian age of the Late Cretaceous epoch, about 72 million years ago. The first fossils were collected in the early 1970s, and the animal was named as a new species of the genus ''Djadochtatherium'' in 1974, ''D. catopsaloides''. The specific name refers to the animal's similarity to the genus ''Catopsalis''. The species was moved to the genus ''Catopsalis'' in 1979, and received its own genus (''Catopsbaatar'', Greek and Mongolian for 'visible hero') in 1994. Five skulls, one molar, and one skeleton with a skull are known; the last is the genus' most complete specimen. ''Catopsbaatar'' was a member of the family Djadochtatheriidae. The skull of ''Catopsbaatar'' was up to long and, as in other multituberculates, proportionally large. The external appearance of these animals' heads may have been similar to those of rodents. The skull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Djadochtatherium
''Djadochtatherium'' is a mammal genus that lived in Mongolia during the Upper Cretaceous. It coexisted with some of the late dinosaurs. This animal was a member of the extinct order of Multituberculata. It is within the suborder of Cimolodonta, and a member of the family Djadochtatheriidae Djadochtatheriidae is a family of fossil mammals within the extinct order Multituberculata. Remains are known from the Upper Cretaceous of Central Asia. These animals lived during the Mesozoic, also known as the "age of the dinosaurs". This famil .... It was named by G. G. Simpson in 1925, the name meaning "Djadokhta beast". The species ''Djadochtatherium matthewi'' was also named by G. G. Simpson in 1925 and has also been known as ''Catopsalis matthewi'' (Simpson, 1925). It has been found in the Campanian (Upper Cretaceous)-age Djadokhta and Goyot Formations of Mongolia. This was a relatively large Multituberculate, with a skull length of about 4.5 cm. It was originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene
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 Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living 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.
