Miocene_Mason Posted June 5, 2017 Share Posted June 5, 2017 Okay on my recent and probably last visit to Waynesboro, I found two more possible fossils. The first one I believe to be a burrow just like the last one. The second I think is either the same or just a sediment filled crack, as it seems another younger deposit is over it (it looks like a river from the conglomerate which has pebbles of this maroon shale in it). I think it's waynesboro formation chewsville member, Cambrian in age. The site is pretty unfossiliferous. If anyone wants to check it's by the McDonald's. “...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...

Rockwood Posted June 6, 2017 Share Posted June 6, 2017 I'm not familiar with the formations, but I'm unconvinced these are fossils. The bottom one appears to be where larger mineral crystals have been exposed. Link to comment Share on other sites More sharing options...
abyssunder Posted June 7, 2017 Share Posted June 7, 2017 Considering that the angle between each of the branches and the curved main ax is varying, I think plant material could be ruled out. The other two possibilities might be septarian propagation cracks ( with mineral veins) and trace fossils (without mineral veins). I'm leaning toward the first.

ynot Posted June 7, 2017 Share Posted June 7, 2017 Agree with a geologic piece. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Plax Posted June 7, 2017 Share Posted June 7, 2017 any chance it's Triassic? Link to comment Share on other sites More sharing options...
Miocene_Mason Posted June 7, 2017 Author Share Posted June 7, 2017 @Plax I guess there is a chance, but this is not the right color and texture. I assume you mean Newark group (Gettysburg or new oxford) and I have collected in those before and they are different. The reason I thought waynesboro formation was 1) its in waynesboro and 2) it fits rather nicely with the chewsville members description of "Maroon shale". This is all however from online searching and may be incorrect, but my best guess is waynesboro formation. Another layer does lie above it that seems to be river sediment shale, what formation or age I couldn't tell you though. “...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...
Plax Posted June 7, 2017 Share Posted June 7, 2017 You have it right WhodamanHD. Was just curious because I had seen Triassic rocks that looked similar and my limited Cambrian experience is in the Kinzers. Interesting rocks and a possibility of at least fragments of trilobites if the old papers I googled are any good. Link to comment Share on other sites More sharing options...
