The find includes examples of projectile points representative of the Western Stemmed Tradition dating to about 11,100 radiocarbon years ago. The Western Stemmed Tradition has been thought to have evolved after the dominant Clovis technology, but the find suggests that the two cultures overlapped in time.\n          <\/jats:p>","DOI":"10.1126\/science.1218443","type":"journal-article","created":{"date-parts":[[2012,7,13]],"date-time":"2012-07-13T12:15:30Z","timestamp":1342181730000},"page":"223-228","source":"Crossref","is-referenced-by-count":180,"title":["Clovis Age Western Stemmed Projectile Points and Human Coprolites at the Paisley Caves"],"prefix":"10.1126","volume":"337","author":[{"given":"Dennis L.","family":"Jenkins","sequence":"first","affiliation":[{"name":"Museum of Natural and Cultural History, University of Oregon, Eugene, OR 97403, USA."}]},{"given":"Loren G.","family":"Davis","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Oregon State University, Corvallis, OR 97331, USA."}]},{"suffix":"Jr.","given":"Thomas W.","family":"Stafford","sequence":"additional","affiliation":[{"name":"Centre for GeoGenetics, University of Copenhagen, DK 1350 Copenhagen, Denmark."},{"name":"Stafford Research Laboratories Inc., 200 Acadia Avenue, Lafayette, CO 80026, USA."}]},{"given":"Paula F.","family":"Campos","sequence":"additional","affiliation":[{"name":"Centre for GeoGenetics, University of Copenhagen, DK 1350 Copenhagen, Denmark."},{"name":"Museu da Ci\u00eancia, Universidade de Coimbra, Largo Marqu\u00eas de Pombal, 3000-272 Coimbra, Portugal."}]},{"given":"Bryan","family":"Hockett","sequence":"additional","affiliation":[{"name":"Bureau of Land Management, Nevada State Office, 1340 Financial Boulevard, Reno, NV 89502, USA."}]},{"given":"George T.","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Hamilton College, Clinton, NY 13323, USA."}]},{"given":"Linda Scott","family":"Cummings","sequence":"additional","affiliation":[{"name":"PaleoResearch Institute, 2675 Youngfield Street, Golden, CO 80401, USA."}]},{"given":"Chad","family":"Yost","sequence":"additional","affiliation":[{"name":"PaleoResearch Institute, 2675 Youngfield Street, Golden, CO 80401, USA."}]},{"given":"Thomas J.","family":"Connolly","sequence":"additional","affiliation":[{"name":"Museum of Natural and Cultural History, University of Oregon, Eugene, OR 97403, USA."}]},{"suffix":"II","given":"Robert M.","family":"Yohe","sequence":"additional","affiliation":[{"name":"Anthropology Program, California State University, Bakersfield, CA 93311, USA."}]},{"given":"Summer C.","family":"Gibbons","sequence":"additional","affiliation":[{"name":"Anthropology Program, California State University, Bakersfield, CA 93311, USA."}]},{"given":"Maanasa","family":"Raghavan","sequence":"additional","affiliation":[{"name":"Centre for GeoGenetics, University of Copenhagen, DK 1350 Copenhagen, Denmark."}]},{"given":"Morten","family":"Rasmussen","sequence":"additional","affiliation":[{"name":"Centre for GeoGenetics, University of Copenhagen, DK 1350 Copenhagen, Denmark."}]},{"given":"Johanna L.
