Submit date: 2007-02-20
Location (approximate): Milan, Washtenaw, MI
Stratigraphy: Silica Formation
Age: Erian (Middle Devonian)
Submitter notes: This Platyceras has an inarticulate Brachiopod, Philhedra crenistriata, living on it. In the Devonian seas, if you were solid, someone started living on you quickly. This inarticulate has clear lines radiating from the center as a diagnostic feature and this shows clearly in this picture.
