This month I found a really good orthocerid, plus a partial mold that might be the tarphycerid Nephriticerina. Maybe another from the Rockport Formation.Found among lots of stromatoporoid sponges, coral, brachiopods, crinoids, and a few gastropods and trilobites. Mid Devonian Team Elmers Quarry, Alpena, Michigan, USA.
