Miocene_Mason Posted May 31, 2017 Share Posted May 31, 2017 Okay, so I did not create this with my hammer,scribe, or trusty screwdriver, it's on a different slab than the other one but this one also has some raindrops. It's Triassic Gettysburg formation from near emmitsburg, MD. It is a strange pointed mark almost as if something was pulled across it. Not all is preserved, I know this because it stops and then starts again (last pic). I'm stumped, let me know what you guys think. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 31, 2017 Share Posted May 31, 2017 Plant material, I think.

westcoast Posted May 31, 2017 Share Posted May 31, 2017 I agree. Fragment of plant material. Link to comment Share on other sites More sharing options...
Rockwood Posted May 31, 2017 Share Posted May 31, 2017 The appearance of pyrite would be a positive indicator. 1 Link to comment Share on other sites More sharing options...
Carl Posted May 31, 2017 Share Posted May 31, 2017 I still think it looks more like a tool mark (not yours): where a chisel or some other piece of metal skipped across the rock. Link to comment Share on other sites More sharing options...

I would normally agree with you Carl, ... but these red shales and mudstones/sandstones are very unforgiving of tool marks - they show up white, even after weathering. I have seen many plant fragments in these rocks that look the similar. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Carl Posted May 31, 2017 Share Posted May 31, 2017 Then I absolutely agree! Thanks, Tim. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted May 31, 2017 Author Share Posted May 31, 2017 Yeah, it's not I took mark, it would have looked deeper and dustier. Also, I didn't do it and I found this site so no one as far as I know has collected there. The site may have had some work in the 1800's for other reasons than fossils, but the tool marks would be different. This piece appeared to have fallen off the outcrop naturally. Another question, Is there a paper or a source of info for upper jurrasic plants, perhaps even plants of the Gettysburg formation? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
