two fossilized sections from a tusk of Gomphotherium, a relative of the Mastodon. These two tusk pieces were found together within river gravel in Sedgwick County, Kansas.

The distal tusk section is 5.2" long and the proximal section is 4.7" long. The proximal-most end of the tusk has been stabilized with glue. Both sections are included with this purchase.

About Gomphotherium

Gomphotherium was an extinct genus of elephant-like creatures that lived from the Miocene to Pleistocene Epochs (about 13.6 million to 1.7 million years ago). It had a wide distribution across Africa, Europe, Asia, and North America, and was an ancestor of modern elephants. Unlike today's elephants, Gomphotherium had tusks in both its upper and lower jaws, with the lower tusks being shovel-shaped, likely used for digging or feeding on vegetation.

Standing around 10 feet tall and weighing up to 6 tons, Gomphotherium inhabited various environments, from wetlands to forests. Its fossils, found worldwide, have helped paleontologists understand the evolution of proboscideans, a group that includes elephants and mammoths. Although it eventually went extinct due to climate change and competition, Gomphotherium remains a key figure in studying elephant evolution.

Fossil evidence indicates that Gomphotherium inhabited a wide variety of environments, from forests to grasslands and wetlands. Its broad distribution across continents suggests it was a highly adaptable creature capable of thriving in different climates and ecosystems.

Gomphotherium likely led a semi-aquatic lifestyle in some regions, similar to that of hippos today, given the shovel-shaped lower tusks, which could have been ideal for scooping up aquatic vegetation. In forested areas, it may have used its tusks and trunk to browse on leaves and bark. Its omnivorous diet helped it survive across varying environments, from dense forests to open plains.

Gomphotherium holds a crucial place in the evolutionary history of elephants. While not a direct ancestor of modern elephants, it is part of the same family tree. Gomphotherium’s tusks and trunk are examples of early adaptations that later evolved into the characteristics seen in today's elephants.

The genus also highlights the incredible adaptability of proboscideans. Over millions of years, various branches of this family have adapted to different environmental challenges, resulting in the evolution of several species, including the woolly mammoth, mastodon, and the elephants we know today.
