Following the publication of the original article [1], it has been brought to the authors' attention that the rights to the minerals and fossils excavated at the site are federally owned by the US Forest Service and are not under the jurisdiction of the Board of Commissioners of Delta County, Michigan. Therefore, future research of the locality will require a federal permit.
