The discovery marks a major milestone in paleontological research and is the first of its kind found in Maryland since 1887, officials say.

The fossils found at Dinosaur Park are from the early Cretaceous period which occurred approximately 50 million years before the Tyrannosaurus rex.

The park is also home to Astrodon johnstoni, the Maryland State dinosaur and the largest species found east of the Mississippi River.
