本文描述了采自大连骆驼山金源洞的早更新世马标本。新报道的标本包括两种类型。大尺寸形式被标识为E。sanmeniensis。小尺寸形式被标识为E。泰哈迪。e. sanmeniensis与另一个巨大的物种E. wangi。在进一步比较E. sanmeniensis，这两个种之间的差异更为明显。目前，金源洞早更新世马化石包括E. sanmeniensis、山梅E. teilhardiandE. qingyangensis，与泥河湾动物群（s.s.）与甘肃巴家嘴动物群相似。在中国早更新世马属中，中型马属分布广泛，而大型马属分布相对有限，这可能与适应性的差异有关。从早更新世到晚更新世，野马群落似乎一直保持着一个大型种与两个中型种共存的格局，中型种的四肢分别是细长的和粗壮的。这种模式发生在2.1 Ma左右，可能是在马属从北美到欧亚大陆的第二次移民事件中建立的。
Early PleistoceneEquusspecimens collected from Jinyuan Cave, Luotuo Hill, Dalian, have been described. The newly reported specimens include two forms. The large-sized form is identified asE. sanmeniensis. The small-sized form is identified asE. teilhardi. E. sanmeniensisshares highly similar features with another huge-sized speciesE. wangi. Based on further comparison of the new and classic specimens ofE. sanmeniensis, the differences between these two species are more obvious. For now, Early PleistoceneEquusin Jinyuan Cave includesE. sanmeniensis, E. teilhardiandE. qingyangensis, same as the composition of Nihewan fauna (s.s.) in Hebei and similar to Bajiazui fauna in Gansu. Among Early PleistoceneEquusin China, medium-sized forms are wide distributed, while distributions of large-sized form are relatively limited, and this is likely relative to difference of adaptability. From Early to Late Pleistocene,Equuscommunity seemed to keep in a pattern of one large-sized species accompanied with two medium-sized species with slender and robust limbs, respectively. This pattern had occurred since around 2.1 Ma, likely established during the second immigration event ofEquusfrom North America to Eurasia.
