Table 4 in Middle Miocene bovids from Mae Moh Basin, Northern Thailand: The first record of the genus Eotragus from Southeast Asia

Table 4. Morphological comparisons of the horn cores of different species of Eotragus within the same localities, including Eotragus clavatus from Sansan, France (morphotype A: MNHN Sa 1113, Sa 1115, Sa 1183, Sa 1195, and Sa 2514; morphotype B: MNHN Sa 2524, Sa 10780, and Sa 10788), Eotragus aff. clavatus from Tarazona de Aragón, Spain (UPV T5.10 and UPV TE.420), and Eotragus lampangensis sp. nov. (UPP MM-68) and Eotragus cf. lampangensis (UPP MM-29) from the Mae Moh Basin, Thailand. The full height of the horn core compared to its basal (anteroposterior and mediolateral) diameters was calculated as EH/DAP (<2.5 = short, 2.5-3 = medium,> 3 = long) and EH/DML (<3 = short, 3-4 = medium,> 4 = long). See SOM for further details. Abbreviations: DAP, anteroposterior diameter of the horn core; DML, mediolateral diameter of the horn core; EH, full height of the horn core.
