About Dinosaur Park

Join us in unearthing the prehistory of Prince George’s County at Dinosaur Park! The Park preserves a rare deposit of fossils from the early Cretaceous Period, about 110 million years ago. From the Maryland State DinosaurAstrodon johnstoni  to early flowering plants, the fossils found at Dinosaur Park help scientists reconstruct our region’s ancient history.

Located in Laurel, Maryland, Dinosaur Park preserves one of the most important dinosaur fossil sites east of the Mississippi River. During interpretive programs, citizen scientists of all ages can take part in the ongoing search for fossils. Visitors can also explore a garden of Cretaceous-era plants and a climbable dinosaur skeleton. Interpretive signs describe Maryland’s dinosaurs, the prehistoric environment, and the African American history of the area.

The garden area and interpretive signs can be visited from dawn to dusk, seven days a week. The fenced fossil site is accessible during free Open Houses from 12 to 4 pm on the first and third Saturdays of each month. For more information, please call the M-NCPPC Archaeology Office at 301-627-1286.
