Osbornodon
Osbornodon
("Osborn's tooth") is an extinct genus of bone-crushing canid (canidae) that were endemic to North America
North America
and which lived from the Orellan age of the Early Oligocene
Early Oligocene
to Early Miocene epoch 33.9—15.97 Ma (AEO) and existed for approximately 17.93 million years. [1]

Taxonomy[edit] Osbornodon
Osbornodon
was named by Wang (1994). Its type is Osbornodon
Osbornodon
fricki. It was assigned to Canidae
Canidae
by Wang (1994) and Munthe (1998).[2] Morphology[edit] Two fossil specimens were examined by Legendre and Roth for body mass. The first specimen was estimated to have weighed 22.2 kg (49 lb). The second specimen was estimated to have weighed 20.2 kg (45 lb).[3] Genus[edit] Seven known species of the genus Osbornodon
Osbornodon
existed:

Osbornodon
Osbornodon
fricki (18 Ma) Osbornodon iamonensis
Osbornodon iamonensis
(synonyms: Cynodesmus nobilis, Paradaphoenus tropicalis) (21 Ma), Osbornodon
Osbornodon
renjiei (33 Ma), and Osbornodon sesnoni (32 Ma).

Species[edit] Osbornodon
Osbornodon
scitulus appears to be a transitional species that partially fills a large morphological and stratigraphical gap within the Osbornodon
Osbornodon
genus. Compared to Osbornodon
Osbornodon
renjiei and Osbornodon sesnoni, Osbornodon
Osbornodon
scitulus possesses derived characters such as large frontal sinus, high sagittal crest, narrow infraorbital canal, short bulla, and broad premolars. O. scitulus differs from Osbornodon wangi in larger size and relatively wider P3 and shorter P4. O. scitulus is distinguishable from Osbornodon iamonensis
Osbornodon iamonensis
and later species in its primitive characters such as a non-elongated rostrum, paroccipital process that is not expanded posteriorly, mastoid process not reduced, and p4 not differentially enlarged relative to p3 (Wang, 2003). References[edit]
