Osbornodon ("Osborn's tooth") is an extinct genus of canid that were endemic to North America and which lived from the Oligocene to the Early Miocene, 33.9—15.97 Ma (AEO), existing for approximately 18 million years. ^[1] It was the last surviving genus of the hesperocyonine subfamily, the oldest subfamily of canids.^[2] The genus is named for Henry Fairfield Osborn.^[3]

Species

Seven known species of Osbornodon existed:

Osbornodon brachypus Cope 1881
Osbornodon fricki Wang 1994 (18 Ma)
Osbornodon iamonensis Sellards 1916 (21 Ma)
Osbornodon renjiei Wang 1994 (33 Ma)
Osbornodon sesnoni Macdonald 1967 (32 Ma)
Osbornodon scitulus Hay 1924
Osbornodon wangi Hayes 2000

The earlier species were about the size of a small fox, and had teeth suggesting an omnivorous or hypocarnivorous diet. Later species were larger and more actively predaceous. The last species, O. fricki, was about the size of a large wolf.^[2]

-Seven known species of the genus ''Osbornodon'' existed:
-*''Osbornodon fricki'' (18 Ma)
-*''Osbornodon iamonensis'' (synonyms: ''Cynodesmus nobilis'', ''Paradaphoenus tropicalis'') (21 Ma), ''Osbornodon renjiei'' (33 Ma), and ''Osbornodon sesnoni'' (32 Ma).
 ==Species==
+Seven known species of ''Osbornodon'' existed:
-''Osbornodon scitulus'' appears to be a transitional species that partially fills a large morphological and stratigraphical gap within the ''Osbornodon'' genus. Compared to ''Osbornodon renjiei'' and ''Osbornodon sesnoni'', ''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 ''O. 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).
