In a remarkable turn of events, a six-year-old boy made an extraordinary fossil discovery during a summer event at Schramm Park State Recreation Area, situated near Gretna in Nebraska. Leo Youngdahl, who hails from Eagle, embarked on a quest in search of crinoid fossils, a common find at the park. However, his exploration took an unexpected direction when he stumbled upon something entirely different.

While attending a late-summer Rafting and Rocks event, Leo turned over a large rock and noticed a distinctive pattern on its underside. This pattern, reminiscent of the scales on a garter snake’s belly, piqued his curiosity. Recognising that his discovery was not typical of the fossils usually found in the area, he sought the assistance of Kelly Ekue, an outdoor education specialist at the Schramm Education Center.


Ekue, who has conducted programmes at the park for over seven years, quickly realised that Leo’s find was unlike any of the six main types of fossils typically unearthed in the region. The imprint appeared larger than usual and bore a fish-like quality, somewhat perplexing given that the park’s geology generally yields marine invertebrates rather than fish remains.
Intrigued by the find, Ekue shared a photograph of the fossil with a geologist, which eventually led to further analysis by experts, including paleontologist Shane Tucker from the University of Nebraska State Museum and geologist Bob Diffendal. Through their examination, they identified the specimen as a conulariid, an ancient marine creature that thrived between 200 million and 500 million years ago. Characterised by a jellyfish-like, upside-down pyramid shape, conulariids are known for their rarity due to their soft bodies and fragile skeletons, which seldom survived the fossilisation process.
The fossil, measuring 2.75 inches in length, bore a unique herringbone pattern that ultimately helped in its identification. Notably, it has been confirmed that similar conulariid fossils had not been documented in Nebraska for over 55 years, with the last known finds occurring in Louisville and Weeping Water.
Ekue expressed astonishment at Leo’s ability to not only find such a rare specimen but also to recognise its significance amidst the numerous rocks at the park. “It’s truly remarkable that among all those rocks, Leo not only picked up this one but also knew to ask about it,” she commented.
For young Leo, the excitement of this discovery was amplified by the fact that he had never before found a complete fossil, let alone one of this scale. He recalled being told that his find was “rarer to find than a mammoth bone,” which added to the thrill of his adventure. Although he will not be allowed to take the fossil home, it will be displayed at Schramm Park, where park staff intend to incorporate it into educational programmes for future visitors.
As he continues his fossil-hunting journey, Leo is already looking forward to his next adventure, whether that involves ancient creatures, peculiar rocks, or other wonders of the natural world. Kelly Ekue expressed hope that Leo’s discovery would inspire others to take a closer look at their surroundings. “Every discovery is important, not just the major ones like rare fossils, but also the smaller ones, such as a neat mushroom or a curious insect,” she remarked.
This unexpected find not only marks a significant moment in the young fossil hunter’s life but also serves as a reminder of the wonders that nature has to offer. With a newfound appreciation for the intricate details of the environment, Leo Youngdahl exemplifies the spirit of inquiry that encourages exploration and learning in the great outdoors.
