Chapter 1: A Glimpse into the World of Oreodonts

Let’s take a moment to delve into the intriguing life of oreodonts, creatures that have largely faded from public consciousness.

Once, in a grassy landscape, a creature emitted an alarm call before vanishing behind a knoll. What was it? With hooves reminiscent of a small pig and a face that seems to meld the features of a goat and a groundhog, this animal is quite peculiar. Nearby, two smaller versions have been nibbling on grass, but they too scurry away to follow their mother into a burrow. All three oreodonts are now hidden from view.

The cause of their alarm soon appears. It resembles a cat at first glance, yet something feels off. Its low-slung body, long tail, and saber-like teeth suggest a feline, but its movements tell a different story. The creature’s legs are structured unlike any cat, and its nose bears more resemblance to a ferret's. Notably, its chin features large flanges that shield its knife-like canines. When it closes its mouth, the teeth are neatly tucked behind those flanges, safe from harm.

The nimravid, a prime example of Hoplophoneus, casually strolls past the oreodont burrow, not on the hunt but merely patrolling its territory before continuing towards the river.

Meanwhile, underground, the oreodonts huddle together. Their burrow is snug, fitting all three comfortably as the younger ones curl up against their mother. Eventually, lulled by their rhythmic breathing, she lowers her head to rest, though one ear remains attuned to the sounds of the outside world.

This world of oreodonts was once our own, yet it feels foreign. Vast grasslands stretched across central North America, transforming the ecological balance forever. Areas now regarded as harsh badlands were lush and vibrant, interspersed with winding rivers. Birds of prey soared overhead, while turtles and fish thrived in the waters, and mammals roamed the land, though they bore little resemblance to the creatures we know today.

Many likely dug burrows, although some, like the Florida oreodont—which lacked sexually dimorphic canines—might have lived in herds. Some in this superfamily had tapir-like proboscises, while others did not. The term “oreodont” translates to "mountain tooth," aptly describing their fossilized jawbones, which resemble a miniature mountain range.

When we see only the stark remains of these extinct creatures, it’s easy to forget they were simply living their lives. Often, they are remembered as prey for predators like hellpigs and beardogs, or nimravids—often inaccurately dubbed "false sabertooth cats." Yet, they had their own lives, family bonds, and likely shared warm moments in their underground homes.

Oreodonts are among the most frequently found fossil mammals in North America, existing from the Eocene to the Pliocene. Despite their prevalence, they remain largely uncelebrated in artwork. Few outside dedicated paleontologists are even aware of their existence. I aim to change that narrative.

No living species today is descended from oreodonts, making them hard to visualize in comparison to familiar animals. Nevertheless, their existence is significant, as they once thrived on our planet.
