In September 2021, I was collecting in Alpena Michigan USA. While there I found
something that was not immediately apparent what it was. After consulting
with
Paleo Joe he told me it was a fan bryozoan holdfast fossil. It was
found in the Potters Farm Formation of the Traverse Group. The fossil
dates to the middle Devonian Period (Givetian Stage). Only found this one and was a little thrown off as I don't remember ever encountering a holdfast that looked like this.
