Allodon Posted October 10, 2020 Share Posted October 10, 2020 I found this rock alone under a tree, so I'm pretty skeptical of it, but I'm also pretty curious. I looked up trace fossils that might look like this, and I thought it was pretty similar to Rusophycus. The rocks around it are from the Glenshaw and Cassleman Formations of late carboniferous Pittsburgh. The "print" is about 10 cm long in its entirety, and maybe a quarter cm deep or so. Could this be a print of sorts or is it just some funky weathering? Thanks! Link to comment Share on other sites More sharing options...

Top Trilo Posted October 10, 2020 Share Posted October 10, 2020 Im not sure if it is a fossil. Is it concave or convex?

I searched a picture of both of them and this one seems to fit best, Psammichnites Rusophycus “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Fossildude19 Posted October 10, 2020 Share Posted October 10, 2020 I'm not convinced this is a trace fossil. The edges of it are a bit jagged. It looks more to me like a fracture pattern . I don't see any definite ridges where trackmarks would show. I think this is just the way the rock fractured, then weathered.
