Bryozoan Holdfast Fossil

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.
