Fossilized burrow traces from the Moscow formation
I don't usually collect random fossil traces when in the field, but I felt these two examples would be worth saving. I'm not sure what the official genus and species name is for them but they are nice examples of small worms (maybe trilobites or another arthropod?) burrowing through the Windom shale when it was still mud.
Specimen #2 has some pyrite preservation.
These specimens were found at a borrow pit on Deep Springs Road in Madison County, NY which exposes the Windom shale member of the Moscow formation (middle Devonian in age, Givetian stage.)
