I am forever amazed at all the things I discover about Gettysburg. Who knew these were here? When I came across this, I got so excited, I could hardly contain myself.
A few dinosaur footprints can be seen in the sandstone or siltstone blocks forming the tops of the walls of the road bridge crossing Plum Run on the southern edge of the battlefield. Out of the 50 or so slabs (about 25 on each side) on the Plum Run Bridge, there are dinosaur footprints on about 5 of them. There is one easily visible footprint at the west end of the north wall. (This is located on South Confederate Avenue as you approach the base of Big Round Top.)
