September 21st PGS Meeting - From the Paleozoic to the Present: Tales from Troubled Terranes in the Central Appalachians....by Dr. Christopher M. Bailey, Department of Geology, College of William & Mary
 

The central Appalachian Orogen is an accretionary mountain belt that formed during a protracted interval of collisional tectonics in the Paleozoic. The Blue Ridge province forms the old pre-Appalachian Laurentian margin, and served as a significant mechanical boundary during later deformation. The Virginia Piedmont includes exotic (peri-Gondwanan) terranes that were accreted at various times in the mid- to late-Paleozoic. The record of terrane accretion is recorded by structures in the Piedmont as well as in the sedimentary record in the Appalachian foreland basin. Ductile strike-slip faulting and orogen-parallel elongation are a significant, but under-appreciated component of Appalachian deformation. As the 2011 Virginia (Mw = 5.8) earthquake demonstrated these old Piedmont terranes are not altogether passive.

  Were there dinosaurs in Western Pennsylvania?  

Yes, dinosaurs walked on the land and left behind their footprints and bones, but unfortunately this evidence has been eroded away long ago. It is difficult to imagine the enormous amount of soil and rock that has been carried away by weathering processes in the 60 million years since the end of Cretaceous time. Scientists have estimated that a layer of rock over a mile thick has been eroded since the beginning of the Mesozoic Age and with it all traces of the dinosaurs.

See Dr. John Harpers more thorough explanation for more information.
