Mennecart, Bastien Métais, Grégoire <i>Mosaicomeryx</i> gen. nov., a ruminant mammal from the Oligocene of Europe and the significance of ‘gelocids’ <div><p>The description of new material and the reassessment of specimens previously assigned to <i>Gelocus quercyi</i> lead us to propose a new genus for this species, <i>Mosaicomeryx</i> gen. nov. Moreover, the description of a juvenile skull and other specimens of <i>Prodremotherium elongatum</i>, and comparison with <i>Dremotherium</i>, provide evidence that these two genera are not closely related as previously thought. A phylogenetic analysis based on 40 dental, cranial and postcranial features highlights the misidentification of <i>Gelocus quercyi</i> and suggests that <i>Mosaicomeryx</i> gen. nov. is closely related to <i>Prodremotherium elongatum. Mosaicomeryx quercyi</i> and <i>Prodremotherium elongatum</i> form a monophyletic group of stem Pecora that first appeared in Western Europe by the late Early Oligocene (MP25–26), and <i>Prodremotherium elongatum</i> persisted up to MP28; following this time both taxa appear to be replaced by <i>Dremotherium</i> and <i>Amphitragulus</i>. This time interval covers two major Oligocene faunal and climate changes: Extinction 1 (MP24), associated with regression of the inner European sea, and Extinction 3/Migrations 3 (MP28), associated with Late Oligocene Warming.</p><p><a href="http://zoobank.org/urn:lsid:zoobank.org:pub:CC044612-B707-4CCD-B121-0830DA304396" target="_blank">http://zoobank.org/urn:lsid:zoobank.org:pub:CC044612-B707-4CCD-B121-0830DA304396</a></p></div> Prodremotherium elongatum form;Prodremotherium elongatum;oligocene;mp;Dremotherium;Mosaicomeryx gen;specimen;nov;Extinction;Gelocus quercyi 2015-06-22
