Ashfall Fossil Beds: A Prehistoric Pompeii and a Window into Evolution

Discovery of a Buried Treasure

In the scorching summer of 1971, paleontologist Mike Voorhies and his geologist wife, Jane, stumbled upon a hidden treasure in a Nebraska cornfield. While exploring a deep gully, Voorhies noticed a peculiar jawbone embedded in a thick layer of volcanic ash. Intrigued, he excavated further and unearthed the skull of a baby rhinoceros.

Realizing the significance of his find, Voorhies returned with a team of students to excavate the site. Over two seasons, they unearthed an astonishing 200 skeletons, representing 17 species of vertebrates. The deep ash layer, blown in by prehistoric volcanic eruptions, had remarkably preserved these ancient creatures in three-dimensional detail.

A Prehistoric Pompeii

Ashfall Fossil Beds has been likened to a prehistoric Pompeii, where animals met a slow and agonizing demise. Unlike the inhabitants of the ancient Roman city who perished instantly from volcanic ash and fumes, the animals of Nebraska endured a prolonged and painful death.

The culprit was the inhalation of fine volcanic ash, which caused hypertrophic pulmonary osteodystrophy, a condition characterized by high fevers, swelling, and pathologic bone growths. The animals, drawn to a water hole for relief from the heat, gradually succumbed over a period of days or weeks, depending on their size.

A Glimpse into Evolution

Ashfall Fossil Beds not only offers a glimpse into the horrors of a prehistoric disaster but also provides a rare opportunity to study the process of evolution in action. The site has yielded fossils of horses in various stages of evolution, from three-toed to one-toed species.

As the climate shifted from subtropical jungle to savanna, horses adapted to the changing landscape. Three-toed horses, well-suited for moist environments, gradually gave way to one-toed horses, better equipped for open grasslands. The evolution of the horse was not a linear progression but rather a branching process, with multiple species coexisting at different stages of adaptation.

A Microcosm of the Past

The diversity of species found at Ashfall Fossil Beds provides a snapshot of the ecological community that existed in Nebraska millions of years ago. From tiny birds and turtles to massive rhinos and giant tortoises, the site offers a glimpse into the interconnectedness of prehistoric life.

It also underscores the fragility of ecosystems and the profound impact that catastrophic events can have on the course of evolution. The volcanic eruption that blanketed Ashfall Fossil Beds not only decimated an entire population but also accelerated the evolutionary trajectory of the surviving species.

Ongoing Legacy

Today, Ashfall Fossil Beds State Historical Park welcomes visitors to explore this unique geological and paleontological treasure. Guided tours and exhibits showcase the remarkable fossils and shed light on the processes that shaped life on Earth long ago. As scientists continue to study the site, Ashfall Fossil Beds remains a valuable resource for understanding the past and informing our understanding of the present.
