Maryland before time: Rare dinosaur bone bed uncovered in Prince George’s County

Long before the Chesapeake Bay or I-95 corridor etched the land that would be Maryland, an enormous carnivorous dinosaur lived and died here. About 115 million years later, staff and volunteers at Prince George’s County’s Dinosaur Park say they have unearthed a tibia, or shin bone, belonging to that apex predator of the Early Cretaceous period.
