Liotomus Marshi
''Liotomus'' is a genus of extinct mammal from the Paleocene epoch (early Cenozoic era). It lived in Europe and North America, and was a member of the extinct order Multituberculata, lying within the suborder Cimolodonta and possibly the family Cimolodontidae. The genus ''Liotomus'' was named by E. D. Cope in 1884. This genus is sometimes placed within family Eucosmodontidae (Jepsen 1940). Species *''Liotomus marshi'' (Lemoine, 1882) ** ''L. marshi'' remains are known from the Upper Paleocene of Cernay, France. ** ''L. marshi'' has been cited as a descendant of ''Anconodon gidleyi''. *''Liotomus vanvaleni'' ** ''L. vanvaleni'' remains are known from the San Juan Basin, New Mexico.

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cimolodontidae
Cimolodontidae is a family of fossil mammals within the extinction, extinct Order (biology), order Multituberculata. Representatives are known from the Upper Cretaceous and Paleocene of North America. The family Cimolodontidae was named by Othniel Charles Marsh in 1889 and is part of the suborder Cimolodonta within the Taxonomic rank, superfamily Ptilodontoidea.

Paleocene Genus Extinctions
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic 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 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. In the Paleocene, the continents of the Northern Hemisphere were still connected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptilodontoids
Ptilodontoidea is a group of extinct mammals from the Northern Hemisphere. They were generally small, somewhat rodent-like creatures of the extinct order Multituberculata. Some of these genera boast a great many species, though remains are generally sparse. '' Ptilodus'' is among the best known, and there's a tendency to depict it as an analog of a squirrel. Upper Cretaceous remains are known from North America and Europe. Later representatives (Paleocene - Eocene) hail from North America, Europe and Asia. These were some of the last multituberculates, and they are within the suborder Cimolodonta. The superfamily is further divided into the following families: *Neoplagiaulacidae - 10 genera; * Ptilodontidae - 4 genera; *Cimolodontidae Cimolodontidae is a family of fossil mammals within the extinction, extinct Order (biology), order Multituberculata.

American Naturalist
''The American Naturalist'' is the monthly peer-reviewed scientific journal of the American Society of Naturalists, whose purpose is "to advance and to diffuse knowledge of organic evolution and other broad biological principles so as to enhance the conceptual unification of the biological sciences." It was established in 1867 and is published by the University of Chicago Press. The journal covers research in ecology, evolutionary biology, population, and integrative biology. , the editor-in-chief is Daniel I. Bolnick. According to the ''Journal Citation Reports'', the journal had a 2020 impact factor of 3.926. History The journal was founded by Alpheus Hyatt, Edward S. Morse, Alpheus S. Packard Jr., and Frederick W. Putnam at the Essex Institute in Salem, Massachusetts Salem ( ) is a historic coastal city in Essex County, Massachusetts, located on the North Shore of Greater Boston.

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 Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and ... 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. The taxonomic name Eucosmodontidae was given by Jepsen in 1940. Some authors interpret this version of Eucosmodontidae and Microcosmodontidae as being subfamilies rather than families.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
