Western Heritage Museum and Lea County Cowboy Hall of Fame

December 12, 2025 - November 9, 2026

STAN was collected in northwestern South Dakota in 1992 by Stan Sacrison. It was only after the bones were prepared, however, when it was realized that this specimen included the best skull of all Tyrannosaurus rex specimens ever collected! 

Not only was STAN’s skull virtually complete, but the bones were preserved in pristine condition. Perhaps even more important is the 50-plus bones of the skull were found mostly disarticulated (separated), allowing for more detailed study than any other T. rex skull. 

Thank you, and enjoy the rest of the exhibit!
