The new Lagerst\u00e4tte hosts a moderately diverse fauna of medusae, linguloid brachiopods, non-mineralized arthropods and orthocone nautiloids, alongside dasycladalean green algae. The biota is similar to those of Lagerst\u00e4tten from the Late Ordovician of Canada, revealing an extensive distribution of a distinctive marginal marine palaeocommunity in Laurentia at this time. The Big Hill biota extends the geographical range of exceptionally preserved Late Ordovician faunas in Laurentia and indicates that further examples remain to be discovered.<\/jats:p>","DOI":"10.1144\/jgs2016-059","type":"journal-article","created":{"date-parts":[[2016,9,10]],"date-time":"2016-09-10T00:58:24Z","timestamp":1473469104000},"page":"18-22","source":"Crossref","is-referenced-by-count":20,"title":["A new Lagerst\u00e4tte from the Late Ordovician Big Hill Formation, Upper Peninsula, Michigan"],"prefix":"10.1144","volume":"174","author":[{"given":"James C.","family":"Lamsdell","sequence":"first","affiliation":[{"name":"Department of Geology and Geophysics, Yale University, New Haven, CT 06511, USA"},{"name":"Present address: Division of Paleontology, American Museum of Natural History, Central Park West at 79th Street, New York, NY 10024, USA"}]},{"given":"Steven T.","family":"LoDuca","sequence":"additional","affiliation":[{"name":"Department of Geography and Geology, Eastern Michigan University, Ypsilanti, MI 48197, USA"}]},{"given":"Gerald O.","family":"Gunderson","sequence":"additional","affiliation":[{"name":"6413 Elmwood Avenue, Middleton, WI 53562, USA"}]},{"given":"Ronald C.","family":"Meyer","sequence":"additional","affiliation":[{"name":"352e Raintree Ct., Louiseville, CO 80027, USA"}]},{"given":"Derek E.
