Hi all,
I am new to this forum, thank you for accepting me here.
I am a geologist from Brazil, but live in Rochester, NY. Paleontology is not my main expertise.
So a friend went to Salmon River, Oswego County, and brought back these fossil-bearing shales he collected there. He told me you can find many fossils in that area and that he was told these are Devonian in age.
I looked in a USGS geologic map, and the region is located where the 'Pulaski and Whetstone Gulf Formations' and the 'Oswego Sandstone' outcrops. These are supposed to be Upper Ordovician. The rocks contain shells that I can't identify (pictures attached).
Can anyone help with the fossil ID and confirm the age of these rocks?
Thank you!
Fabiana
