DFW Airport employees discovered fossils believed to be more than 11,000 years old earlier this month.
Two Dallas-Fort Worth International Airport employees found pieces of mammoth tooth Nov. 2 along a creek on the airport's property, the airport wrote in a tweet. The very next day, employees discovered a bison thigh bone during a "Life Saver Exercise."
The fossils are the first remains dating to the Ice Age recovered on airport property.
An airport spokesperson tells NBC 5 the bones are still at the airport, but will be moved to SMU Thursday for study and preservation.
