As I traveled from Minnesota to Morrison Iowa for a mineral/fossil presentation that our rock club was involved in, I had a few hours to venture off course and visit Bird Hill in Floyd County. The exposure provides fossils from the Cerro Gordo, Lime Creek, Devonian Period. If anyone has visited the Rockford Tile and Brick Quarry, the same strata is exposed at both sites. The Cerro Gordo is brachiopod rich with 40 known species. In my short visit, 15 species of brachiopods were found and HOPEFULLY identified correctly! I do have a bag of brachiopods that I am still trying to work through. So hopefully my count will increase with time. Here are a sampling of the variety the Cerro Gordo provides.
