Fossil Teeth
A big part of my "real" job as a veterinarian is dentistry, so I tend to be a little obsessed with teeth of extinct and extant species.
From the Natural History Museum of Utah
|  | 
| Mammuthus columbi, Columbian mammoth | 
|  | 
| Smilodon fatalis, the saber-tooth cat | 
|  | 
| Bison latifrons, Giant bison | 
|  | 
| Canis dirus, the dire wolf, a very good pupper | 
|  | 
| Paramylodon harlani, Giant sloth | 
|  | 
| Uintatherium | 
|  | 
| This is just the right front part of the maxilla of Arctodus, the giant short-faced bear. That canine tooth is 2-3 inches long. Unlike modern bears, these guys were built for running! | 
From the Museum of Ancient Life
|  | 
| Dimetrodon, my favorite not-a-dinosaur (they lived way before the dinosaurs, and were synapsids--proto-mammals) | 
|  | 
| Another smiling Smilodon | 
|  | 
| Basilosaurus, a proto-whale | 
|  | 
| Mammoth jaw |
