A teenager exploring a friend’s farm in Iowa stumbled across something amazing: a 34,000-year-old mastodon jaw. This jaw, found near a creek, provides a glimpse into the once-bustling prehistoric life in the area, where massive creatures like mastodons, woolly mammoths, and giant sloths roamed millions of years ago. The jawbone, about 30 inches long, likely belonged to a juvenile mastodon, which would have stood around 7 feet tall. Today, it’s safely stored at the University of Iowa’s Paleontology Repository.
The discovery is as fascinating as the fossil itself. While searching for arrowheads, the young teenager uncovered this ancient treasure instead. He carefully brought the heavy jaw back to the farmhouse, where the owners, aware of its significance, preserved it to prevent damage. They quickly reached out to the University of Iowa with the news.
Quick action was critical. If the bone had been exposed to sunlight, the delicate organic material could have dried out. Tiffany Adrain, a collections manager at the repository, mentioned how lucky they were this fossil was found when it was. “We were incredibly fortunate,” she told VICE, noting it was in great condition because it hadn’t been out in the sun long.
Mastodons are fascinating creatures. They share a distant relation with today’s elephants and lived in North America during the Pleistocene Epoch. This jaw adds to the collection at the Iowa Paleontology Repository, which focuses on preserving fossils from the region’s prehistoric past. The repository also features remains of other ancient animals, like giant ground sloths, revealing the rich biodiversity that thrived in North America before the Ice Age.
Interestingly, experts have noted that the frequency of these discoveries is increasing. According to recent surveys, many people unintentionally find fossils while walking, fishing, or farming. “I think people are uncovering ancient remains all the time,” Adrain explained.
The Iowa community plays an essential role in documenting these finds. Local farmers or curious individuals often donate their discoveries, helping the museum expand its collection. Over the years, the repository has received many fossils thanks to the eyes and efforts of residents who share a love for their history.
This mastodon jaw discovery inspires hope for even rarer finds in the future, like those of saber-toothed cats. With over a million specimens to sift through, of which 148,000 have been cataloged, the contributions from the community are critical to understanding the region’s ancient past. These efforts not only enrich scientific knowledge but also bring people together in appreciation of their shared heritage.
