Osbornodon ("
AEO), existing for approximately 18
million years.
[1] It was the last surviving genus of the hesperocyonine subfamily, the oldest subfamily of canids.[2]
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]
