	Multituberculata - Wikipedia, the free encyclopedia
		They are named for their teeth, which had many cusps (tubercles) arranged in rows, hence multituberculates.
		About 80 genera of multituberculata are known, including Lambdopsalis, Ptilodus and Meniscoessus.
		In their 2001 study, Kielan-Jaworowska and Hurum found that most multituberculates could be referred to two suborders: "Plagiaulacida" and Cimolodonta.

	Age of mammals
		Ptilodus is a typical medium-sized multituberculate from the Paleocene of North America.
		Like in squirrels, the foot of Ptilodus was very mobile and could be reversed backward, which allowed the animal to climb down trees with its head pointing downward.
		The dentition of Ptilodus and other multituberculates is most similar to rodents in the enlarged front teeth, especially the pair of lower incisors, which are followed by a gap (called diastema) in the lower jaw.

	Land Animals
		The skeleton of Ptilodus shows several adaptations for life on land and trees, such as their sharp claws and eye sockets that point forward.
		The foot of Ptilodus was very mobile and could be moved in many directions, which allowed the animal to climb down trees while it pointed its head and eyes downward.
		A marked difference from Squirelius is the long prehensile tail, that is similar to some primates found on Earth, which Ptilodus used like a fifth limb when climbing and holding on to trees.

	The Geologic History of Fossil Butte National Monument and Fossil Basin (Paleontology)
		The multituberculate mammal Ptilodus, also present in Torrejonian deposits, is the most "primitive" mammal in the fauna.
		Ptilodus, like most other multituberculates, was specialized in that its fourth lower premolars were expanded into shearing blades, the function of which is not known.
		Ptilodus was in many respects similar to rodents in the development of procumbant incisors and in general build and appearance.

		Ptilodus was like a short-haired squirrel with the tail of an opossum.
		Although Ptilodus lived in the early Tertiary period, about 60 million years ago, the multituberculates originated in the Jurassic period almost 200 million years ago.
		It is believed that it gave birth to live, but immature young, similar to modern marsupials.

	Introduction to Multituberculates (Site not responding. Last check: 2007-11-07)
		Over 200 species are known, some as small as the tiniest of mice, the largest the size of beavers.
		Some, such as Lambdopsalis from China, lived in burrows like prairie dogs, while others, such as the North American Ptilodus, climbed trees as squirrels do today.
		The narrow shape of their pelvis suggests that, like marsupials, multituberculates gave birth to tiny, undeveloped pups that were dependent on their mother for a long time before they matured.

		This conclusion might have important phylogenetic implications, as multituberculates and eutriconodontans may lay closer to the therians sensu strico, than hitherto believed.
		We describe an endocast of the Late Cretaceous multituberculate Kryptobaatar, which differs from those of other multituberculates (Ptilodus, Chulsanbaatar, and Nemegtbaatar) in having unusually long olfactory bulbs and the paraflocculi elongated transversely, rather than ball-shaped.
		In both Jerison’s method and a mean of our series of derived formulae, the EQ varies around 0.71, which is higher than estimated for other multituberculate mammals.
