Eisenmann, Véra & Kuznetsova, Tatiana, 2004, Early Pleistocene equids (Mammalia, Perissodactyla) of Nalaikha, Mongolia, and the emergence of modern Equus Linnaeus, 1758, Geodiversitas 26 (3), pp. 535-561 : 535-561

Equus sp. B

According to the only entire bones – the first phalanges (Annexe: Table 5) –, Equus sp. B was both taller and more robust than E. nalaikhaensis . Its body mass may be estimated at about 600 kg, close to the estimated weight of E. cf. suessenbornensis of Akhalkalaki, Georgia ( Vekua 1986), and the basilar length of the skull at more than 600 mm (Fig. 4).

are slightly smaller but resemble some of those collected in northeastern Siberia and tentatively referred to E. verae Sher, 1971 and a fragmentary MCIII of the early Pleistocene Sergeevo Formation of Kuznetsk Basin referred to E. cf. suessenbornensis ( Foronova 1998, 2001).
