Comparisons with the inner ear of the Eocene early diverging artiodactyl \u003ci\u003eDiacodexis\u003c/i\u003e and perissodactyl \u003ci\u003eXenicohippus\u003c/i\u003e allow refining the picture of the ancestral inner ear morphology of Euungulates. These taxa are very close morphologically and mostly differ by slight differences in their semicircular canal angulations and profile. They all present a secondary crus and a low position of the plane of the lateral semicircular canal relative to the posterior semicircular canal. These two characters, considered as ancestral features for Theria, might be symplesiomorphies of Euungulata as well. \u003ci\u003eHyopsodus\u003c/i\u003e and \u003ci\u003eXenicohippus\u003c/i\u003e share characters also observed in other basal Equoidea, which would support the close relationship between these two taxa previously proposed in the literature. A functional study of the cochlea of \u003ci\u003eHyopsodus lepidus\u003c/i\u003e is also realised to discuss its putative ability of using terrestrial echolocation previously proposed in the literature. The morphology of the cochlea of \u003ci\u003eHyopsodus lepidus\u003c/i\u003e does not indicate a specialisation to sophisticated echolocation such as observed today in microchiropteran bats. However, its estimated audible range of frequencies (208 Hz to 76.8 KHz) would be compatible with terrestrial echolocation.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://tandf.figshare.com/articles/dataset/The_inner_ear_morphology_of_the_condylarthran_i_Hyopsodus_lepidus_i_/1031552","contentUrl":null,"metadataVersion":4,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2014-05-20T09:08:33.000Z","registered":"2014-05-20T09:08:34.000Z","published":"2015","updated":"2020-09-
