Coelacanths have both living representatives and a rich fossil record, but lack fossils older than the late Middle Devonian (385\u2013390\u200aMyr ago), conflicting with current phylogenies implying coelacanths diverged from other sarcopterygians in the earliest Devonian (410\u2013415\u200aMyr ago). Here, we report the discovery of a new coelacanth from the Early Devonian of Australia (407\u2013409\u200aMyr ago), which fills in the approximately 20\u200aMyr \u2018ghost range\u2019 between previous coelacanth records and the predicted origin of the group. This taxon is based on a single lower jaw bone, the dentary, which is deep and short in form and possesses a dentary sensory pore, otherwise seen in Carboniferous and younger taxa.<\/jats:p>","DOI":"10.1098\/rsbl.2006.0470","type":"journal-article","created":{"date-parts":[[2006,4,6]],"date-time":"2006-04-06T14:52:49Z","timestamp":1144335169000},"page":"443-446","source":"Crossref","is-referenced-by-count":49,"title":["Oldest coelacanth, from the Early Devonian of Australia"],"prefix":"10.1098","volume":"2","author":[{"given":"Zerina","family":"Johanson","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, Macquarie UniversitySydney, New South Wales, Australia, 2109"},{"name":"MUCEP, Department of Earth and Planetary Sciences, Macquarie UniversitySydney, New South Wales, Australia, 2109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A","family":"Long","sequence":"additional","affiliation":[{"name":"Museum VictoriaPO Box 666E, Melbourne, Victoria 3000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A","family":"Talent","sequence":"additional","affiliation":[{"name":"MUCEP, Department of Earth and Planetary Sciences, Macquarie UniversitySydney, New South Wales, Australia, 2109"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Janvier","sequence":"additional","affiliation":[{"name":"UMR 5143 CNRS, Mus\u00e9um National d'Histoire Naturelle8 rue Buffon, Paris 75005, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James W","family":"Warren","sequence":"additional","affiliation":[{"name":"Monash UniversityClayton, Victoria 3168, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2006,3,21]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0400609101"},{"key":"e_1_3_2_3_1","unstructured":"Chang M.-M. 1982 The braincase of Youngolepis a Lower Devonian crossopterygian from Yunnan south-eastern China.
