In Depth

       One of the hyaenodonts,‭ ‬Tritemnodon means‭ ‘‬three cutting tooth‭’ ‬and is a reference to how the teeth were formed for greater slicing efficiency,‭ ‬something that hyaenodonts have a reputation for being able to with the greatest ease.‭ ‬The relatively small stature and gracile build of Tritemnodon means that these were most likely predators of smaller vertebrates such as rodent sized mammals.‭ ‬In terms of habitat,‭ ‬most of North America was still dominated by temperate forests that had not yet given way to the expansive grassy plains that would arrive by the Miocene.‭ ‬Therefore Tritemnodon probably lurked around the forest floor sniffing out scent trails left by the smaller animals that it would hunt for prey in a similar manner to how a fox would do today.‭ ‬The long legs and lightweight build of Tritemnodon would mean that an individual would be quite capable of running down even fairly fast prey.
