12-Year-Old Kansas Boy Discovers 85-Million-Year-Old Fossil

When 11-year-old Corbin Bullard spotted something unusual jutting from a Kansas quarry wall, he knew he'd found something special. That moment during a September 2025 field trip turned into the discovery of an 85-million-year-old marine reptile fossil, nearly complete and ready to rewrite his future.

"I didn't know what it was, but I knew that it was something big," Corbin said about finding seven or eight massive vertebrae exposed in the rock. His mother Wendy remembered his immediate reaction: "He said, 'Whoa.'"

The bones belonged to a Tylosaurus, a fearsome marine reptile that hunted when an ancient sea covered the American heartland during the Cretaceous Period. The 12-year-old, now in seventh grade, explained that "pretty much all of the middle of America used to be underwater."

The Sedgwick County 4-H Geology Club returned three more times to carefully excavate the fossil from the Smoky Hills Chalk formation. The team recovered nearly the entire skeleton, including the skull, with only part of the tail missing. The specimen stretches more than 15 feet long.

The excavation presented unique challenges. The Tylosaurus had died with its head cranked backward at an odd angle, making it difficult for the team to identify what they were uncovering. Shannon Crouch, whose daughter Zoe helped with recovery, said the unusual posture initially stumped even experienced club members.

For a geology club whose previous best finds included shark teeth and a partially buried fish fossil, this discovery marked a major milestone. Because Corbin found the fossil on private property with permission, the specimen belongs to him.

He's now spent at least 30 hours cleaning and preparing the bones. He plans to display the skull at the Sedgwick County Fair in July, hoping judges will appreciate the effort. The experience has cemented his dream of becoming a paleontologist.

Sunny's Take

This discovery shows what happens when curiosity meets opportunity. Sedgwick County 4-H agent Stephanie Hays noted that "4-H is definitely meant to help kids find what they're interested in and do amazing things." Club leader Crista Burnett pointed out that beyond the amazing fossil, Corbin has gained public speaking skills and research experience.

Wendy Bullard credited the entire 4-H community for making the discovery possible, from landowners granting access to leaders organizing trips. "This is not something he and I can go out together and do on our own," she said. "It's a 4-H community."

For Corbin and his fellow club members, unearthing Kansas's ancient past has opened doors to an exciting future.
