The Cretaceous Era brought dinosaurs to the area which left a number of fossils, now preserved in a 7.5-acre
(3.0 ha) park in Laurel. The site, which among other finds has yielded fossilized teeth from Astrodon and Priconodon species, has been
called the most prolific in the eastern United States.
In the mid to late Holocene era, the area was occupied by Paleo-Native Americans and then later, Native Americans. When the first European
settlers arrived, what is now Prince George's County was inhabited by people of the Piscataway Indian Nation. Three branches of the tribe are
still living today, two of which are headquartered in Prince George's County.
Prince George's County was created by the English Council of Maryland in the Province of Maryland in 1696 from portions of Charles and
Calvert counties. The county was divided into six districts referred to as "Hundreds": Mattapany, Petuxant, Collington, Mount Calvert,
Piscattoway and New Scotland.
A portion was detached in 1748 to form Frederick County. Because Frederick County was subsequently divided to form the present Allegany,
Garrett, Montgomery, and Washington counties, all of these counties in addition were derived from what had up to 1748 been Prince George's
County.
In 1791, portions of Prince George's County were ceded to form the new District of Columbia, along with portions of Montgomery County,
Maryland, as well as the parts of Northern Virginia; that were later returned to Virginia.
