Geography, geology, and phylogeny in relation to the study material. (A) The location of the study area (black star), details are shown in Fig. S1. The map was generated by GTOPO309 (http://www1.gsi.go.jp/geowww/globalmap-gsi/gtopo30/gtopo30.html) using Globalmapper (v10) (http://www.bluemarblegeo.com/products/global-mapper.php). (B) Stratigraphic column and polarity with palaeomagnetic age (redrawn after refs18,19), also denoting the horizon of study material in the strata (in light yellow). (C) The 50% majority consensus tree from 29 maximum parsimonious trees showing the phylogenetic position of the Gomphotherium species and Tetralophodon longirostris (tree length = 81, CI = 0.617; RI = 0.744, data set in Table S1), the number at each node representing the support value calculated by majority rules (percentages of supported MPTs in the total MPTs, which are always larger than 50%) and the orange frame indicating the sister-taxon relationship of G. steinheimense and T. longirostris. (D) G. steinheimense, IVPP V23283, right m3. (E) G. connexum, IVPP V8576, left M3.
