A couple years ago, my father picked up an Edrioaster sp. in the Galena Formation of Southeast Minnesota. What makes this specimen interesting is that it was preserved fully inflated and showing the holdfast and the outline of the structure it was attached to. We got the specimen back at MAPS this past year after having it prepped and I finally took some photos of it. I just hope I got the genus ID correct. Edrioaster sp. Galena Formation, Prosser Member Ordovician, Trentonian Southeast Minnesota Anotated Feel free to post photos of your Edrioasteroids!
