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.

Atrypa Brachiopod Fossil with Crystallized Lophophore

Check out this picture of an Atrypa (Hall, 1862) brachiopod fossil (note the two elliptical shapes which are feeding tubes or lophophore that have crystallized). The fossil was found in the Genshaw Formation at Alpena, Michigan USA. The creature lived Middle Devonian Period (Erian Stage).

 

Anthonomus defossus? Snout Beetle Fossil

These images show snout beetle or weevil insect fossils of the Order Coleoptera, Family Curculionidae found in the Florissant Formation of Teller County, Colorado, USA. I wonder if this insect was in the Anthonomini weevil tribe in the subfamily Curculioninae and maybe genus Anthonomus (Gemar, 1817) or species Anthonomus defossus (Scudder, 1876).  It dates to the Chadronian Stage (37.2 - 33.9 million years ago) Eocene Epoch of the Paleogene Period. Thanks to Doug for the image. Fossils were uncovered in September 2021. Field of view is 2 mm.
