I just found this fossil in between Boyne City and East Jordan Michigan. It was found in a mound of rock from a gravel pit in the aforementioned area which consists mostly of Devonian fossils (petoskys and other rugose corals for the most part).
I hope I am posting this in the right place, I am new to this forum and it's not easy for me to know where to post in various forums without angering a lot of patrons and administrators, so I went to the "id fossils" section and started a new topic. I hope I got this right!
Also, I apologize for the pics because I was having a hard time shrinking them to a size that would let me post them (I could only get two). I hope the images I provided are enough. The fossil is approximately 5" across and 3 3/4" tall and probably Devonian.
Thanks in advance!
