City works to protect 200 million-year-old dinosaur tracks

The Trustees of Reservations oversees the Holyoke, Massachusetts, site that contains about 130 footprints researchers think were left by carnivorous, two-legged dinosaurs, up to 15-feet tall.

A Trustees' official tells The Republican newspaper (http://bit.ly/23Kwj40 ) that graffiti, plaster casting and vandalism have been problems in the park.
