First European ‘Isectolophidae’ (Mammalia, Perissodactyla): <i>Chowliia europea</i>, sp. nov., from the lower Eocene of Le Quesnoy, France

A new species of the ‘isectolophid’ <i>Chowliia</i>, <i>C. europea</i>, sp. nov., is described from the lowermost Eocene (MP7) Le Quesnoy locality of the Paris Basin. The new species is exclusively known by dental material, and it represents the earliest tapiromorph occurrence in Europe. The morphology of its bunolophodont molars indicates that <i>C. europea</i> is a tapiromorph, and it is here included in the primitive and probably paraphyletic family ‘Isectolophidae.’ <i>Chowliia</i> was previously restricted to the lowermost Eocene Wutu Formation (eastern China), and its occurrence in Europe indicates faunal interchange between continental Asia and western Europe as early as the earliest Eocene. A preliminary analysis of the phylogenetic position of <i>C. europea</i> supports the hypothesis that <i>Chowliia</i> is most closely related to <i>Cardiolophus</i> and to <i>Homogalax wutuensis</i>. http://zoobank.org/urn:lsid:zoobank.org:pub:690B8328-E7F7-45AE-B402-EE3194F74FB4 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Bronnert, C., E.
