Re:States without fossils
Dinosaurs had to deal with mud too, heard there were some nice dinosaur
footprints on the actual site of Gettysberg. Anyone know what type?
I'm going from a field trip paper of the Newark Supergroup, here. There
are pictures of the most common (possible all known) footprints in the Late
Triassic sandstones and shales that also form the broad battlefield plain
of Gettysburg. Wouldn't you know it, we don't have a copy of the Geology of
Adams County handy (this is a state gov't office, BTW). But, along with a
phytosaur,sphenodontid, tanystropheid, lacertilian (?), and various archosaurs,
there are listed: Coelurosaurichnus sp. 1 and 2, Grallator sp. (theropod),
Atriepus sulcatus and A. milfordensis (?ornithischian).
I found some real mucky Grallator (I think) prints in a stream bed
farther north. I also found a "bird-like" track that had been scratched into a
rock and conveniently "left" to be found. I was mortified that someone would do
Due to these gems, and the exciting, often mind-boggling geology around
here, eastern Pennsylvania is far superior for geologists than western PA. Still
looking for the first dinosaur skeletal material in PA, though.
