Examples of "ectypodus"
The genus "Anconodon" was named by Jepsen G.L. in 1940. It is also known as "Ectopodon" (Russell 1967); "Ectypodus" (partly); "Liotomus" (partly); and "Ptilodus" (partly).
The genus was named by paleontologist Edward Drinker Cope in 1881. Cope also mistakenly assigned some material belonging to this genus to "Chirox" in 1884. Elements from "Ectypodus" (Jepsen, 1940) and "Neoplagiaulax" have also been reassigned to this genus.
The genus "Mimetodon" was named by Jepsen G.L. in 1940. It has also been known as "Ectypodus" (partly); "Mesodma" (partly); "Neoplagiaulax" (partly). McKenna and Bell (1997) lists possible material from the Upper Paleocene(?) of Europe.
A couple of isolated teeth which had been previously identified as perhaps belonging to "Ectypodus", have been now been placed within this taxon. All referred specimens are held in the collection of the University of Alberta.
The species was named by C. R. Scott, R. C. Fox, and G. P. Youzwyshyn in 2002. Material assigned by Jepsen in 1940, as amended by Gazin in 1956, to "Ectypodus hazeni" has also been assigned to this species.
The species "Anconodon cochranensis" was named by Russell in 1929 and Van Valen and Sloan in 1966. It has also been known as "A. russelli" (Simpson 1935; Jepsen 1940); "Ectopodon cochranensis" (Russel 1967); "Ectypodus cochranensis" (Simpson 1937a); "Ectypodus russelli" (Simpson 1935d); "Liotomus russelli"; and "Ptilodus cochranensis" (Russell 1929). Fossil remains have been found in the Tiffanian (Middle-Upper Paleocene)-age strata of Alberta (Canada) and Montana and Wyoming (United States). It has been cited as a descendant of "A. gidleyi". The holotype is in the University of Alberta collection. The body mass has been estimated to be about 55 g, the weight of two standard mice.
Parectypodus ("besides "Ectypodus"") is a genus of extinct mammal that lived from the Paleocene to the Eocene of North America. Some of the known fossil material may also be from the Upper Cretaceous. It was named by G.L. Jepsen in 1930.
The species "Mimetodon silberlingi" was named by Simpson G.G. in 1935 and Schiebout in 1974. It has also been known as "Ectypodus? silberlingi" (Simpson 1935d); "Mesodma silberlingi" (Van Valen & Sloan 1966); and "?M. nanophus". Remains were found in the Torrejonian-Tiffanian (Middle Paleocene)-age strata in the Gidley Quarry of Montana and in Wyoming, North Dakota and Alberta, Canada. This species weighed an estimated 20 g.
The multituberculates existed for about 166 or 183 million years, and are often considered the most successful, diversified, and long-lasting mammals in natural history. They first appeared in the Jurassic, or perhaps even the Triassic, survived the mass extinction in the Cretaceous, and became extinct in the early Oligocene epoch, some 35 million years ago. The oldest known species in the group is "Indobaatar zofiae" from the Jurassic of India, some 183 million years ago, and the youngest are two species, "Ectypodus lovei" and an unnamed possible neoplagiaulacid, from the late Eocene/Oligocene Medicine Pole Hills deposits of North Dakota. If gondwanatheres are multituberculates, then the clade might have survived even longer into the Colhuehuapian Miocene in South America, in the form of "Patagonia peregrina".
However, the idea that multituberculates were replaced by rodents and other placentals has been criticised by several authors. For one thing, it relies on the assumption that these mammals are "inferior" to more derived placentals, and ignores the fact that rodents and multituberculates have co-existed for at least 15 million years. According to some researchers, multituberculate "decline" is shaped by sharp extinction events, most notably after the Tiffanian, where a sudden drop in diversity occurs. Finally, the youngest known multituberculates do not exemplify patterns of competitive exclusion; the Oligocene "Ectypodus" is a rather generalistic species, rather than a specialist. This combination of factors suggests that, rather than gradually declining due to pressure from rodents and similar placentals, multituberculates simply could not cope with climatic and vegetation changes, as well as the rise of new predatory eutherians, such as miacids.
