Physical Characteristics of Hyaenodon

Understanding the physical traits of Hyaenodon helps paint a picture of what these ancient predators looked like.

  1. 06Hyaenodon had a long skull, which could measure up to 24 inches in larger species.
  2. 07Their jaws were incredibly powerful, designed to crush bone and tear flesh.
  3. 08They had a robust body, with strong limbs that suggest they were capable runners.
  4. 09Hyaenodon possessed sharp, serrated teeth ideal for slicing through meat.

  5. 15Some species of Hyaenodon even lived in areas that are now deserts.

Hyaenodon's Diet and Hunting Behavior

What did Hyaenodon eat, and how did it hunt? These facts shed light on its predatory lifestyle.

  1. 16Hyaenodon was a hypercarnivore, meaning its diet consisted mostly of meat.
  2. 17They likely hunted in packs, similar to modern wolves, to take down larger prey.
  3. 18Hyaenodon may have scavenged as well, feeding on carcasses left by other predators.
