NEW ULM — Brown County Historical Society has revealed the age of a prehistoric mammoth’s partial tusk discovered in New Ulm a few years ago.
The radiocarbon date of the tusk is 22,136 years, BCHS collections curator Ryan Harren announced during the conclusion of an event Saturday at BCHS’ museum.
Last year the New Ulm company M.R. Paving & Excavating donated the partial tusk to the museum. It is the remains of an animal species that went extinct near the end of the last ice age.
