In early 1994, during the installation of drain tile patterns in a southeast Wisconsin cornfield, workers ran into what has become one of North America’s most important Ice Age discoveries - a nearly complete skeleton of a woolly mammoth. Named the Hebior Mammoth, this specimen and its surrounding site was carefully excavated over 6 months by a professional archaeology team

Not only is this specimen one of the largest and most complete (85%) Mammuthus primigenius ever found in North America, its importance is underscored by the fact it was butchered by paleoindians 11,000 years ago. Numerous pry marks, chop marks, stone tool cuts and wedge compressions are apparent on several bones. The skeleton was carefully disarticulated, butchered and then stacked in a pile. In addition, the skull was removed and the cranium broken into from the palate region presumably to extract the brains.
