Okay maybe its not a dinosaur arm but it almost looks like one. Anyone have any idea what kind of fossil it is? I found it eroded out of a shale/slate formation in PA.
I wanted to clarify that it didnt erode out of that hole in eock formation, and that it was sitting on the ground in a pile of debris beneath that type of formation. It looks like chicken skin!
In the 19th century, due to the reptilian look of the diamond-shaped leaf scar pattern, petrified trunks of Lepidodendron were frequently exhibited at fairgrounds by amateurs as giant fossil lizards or snakes.
From looking at the other images on google, it looks like I have a nice piece! How do you guys preserve your fossils? I want to keep this guy and dont want him to break, what are my options in preservation? I was thinking about polyurethane? I don't want it to shine though, i want it to look natural and dull.
I have a chunk next to my garage door for use as prop door holder. It was bleached white by the sun when I found it. I find pieces fairly frequently while fishing streams and rivers.
It's pretty much a rock now, so I'd imagine the only required preservation is avoid direct light.
I dont see any real need to preserve it more than just a cleaning. You might see about having a small slab cut out and polished to check for internal details to increase its worth as a conversation piece Good find however.
Soooo you guys are saying don't marinate the chicken? I'll have to get an etch on the top or bottom though I think thats a good idea ddancer. Maybe even like a 45 degree angle one halfway through it then cut it flat on that plane in the center out to the edge an inch... Thanks everybody for all comments and info
