Hi, all. I just returned from a trip to northern Michigan. My wife was kind enough to indulge my fossil-hunting hobby, and I collected specimens in four locations: at a state park in Rockport, a city park in Rogers City, the Lake Huron shoreline in Alpena, and a rare (in Michigan, at least) road cut along a state highway. Here are some of my findings. First is a large Petoskey stone, or Hexagonaria peraninata.
