Figure 1. Geographic distribution of E. (Sussemionus) ovodovi specimens investigated at the DNA level and pre-molar and molar morphology.
(A) E. (Sussemionus) ovodovi geographic range. The three red circles indicate the archaeological sites analyzed in this study. The site (Honghe) that delivered the complete genome sequence at 13.4-fold average depth of coverage (HH06D) is highlighted with a square. The black circles indicate sites that provided complete mitochondrial genome sequences in previous studies (Druzhkova et al., 2017; Orlando et al., 2009; Vilstrup et al., 2013; Yuan et al., 2019). The temporal range covered by the different samples analyzed is given in years before present (YBP) and follows the name of each site. Numbers between parentheses indicate the number of samples for which DNA sequence data could be generated. (B) Facies masticatoria dentis of P2, M3, p2, and m3 for the E. (Susseminous) ovodovi samples of the Honghe site analyzed here (a), E. Sussemionus (Eisenmann, 2010) (b), and E. caballus (Laboratory specimen) (c). 1, 4 protocones; 2, 5 metacones; 3 caballine notch. Teeth from the right side are shown, except for E. Sussemionus. The erupted teeth of the samples of the Honghe site appear to be smaller than those of the E. Sussemionus specimen.
