Port Kennedy Bone Cave
|Port Kennedy Bone Cave|
|Location||Valley Forge National Historic Park, Port Kennedy, Pennsylvania|
The Port Kennedy Bone Cave is a limestone cave in the Port Kennedy section of Valley Forge National Historical Park, Pennsylvania, USA. The Bone Cave "contained one of the most important middle Pleistocene (Irvingtonian, approximately 750,000 years ago) fossil deposits in North America".
The fossils in the cave were investigated by noted 19th-century palaeontologists Edward Drinker Cope, Henry C. Mercer, and Charles M. Wheatley. Some of the fossils, such as an unnamed member of Genus Dicaelus are unique to this cave and have not been identified elsewhere.
The cave was originally discovered by limestone miners in the 19th century. It was later filled in with asbestos-bearing industrial refuse and the cave's location was lost. The village of Port Kennedy was largely demolished in the 1960s during construction of the U.S. Route 422 Expressway. The tract containing the cave became part of the Valley Forge National Historical Park in 1978. In 2005, the National Park Service and geologists rediscovered the cave.
