描述了广西百色及永乐盆地发现的中始新世最晚期一晚始新世的猪类化石。这批已知最早的猪超科化石,大大丰富了亚洲地区的早期猪类,对了解全球猪类的早期演化有着重要价值。广西的材料被确定为两个新属新种:萨氏始新猪Eocenchoerus savagei和广西华夏猪Huaxiachoerus guangxiensis,一个新种:粗壮暹罗猪Siamochoerus viriosus和一个未定属种:Tayassuidae gen.et sp.indet。加上已发表的单尖旅猪Odiochoerus uniconus,百色、永乐盆地共计发现了5种始新世猪类化石。新属Eocenchoerus虽然臼齿结构简单,与原始的古猪类(paiaeochoerid)接近,但因其M3具有一个明显的跟座而被归入猪科。早期猪科动物非常原始的臼齿形式证明,猪科动物的起源并不晚于古猪科(Palaeochoeridae)和西科(Tayassuidae)。旧大陆的古猪类长期以来被认为与新大陆的西类(tayassuid)更为接近,多数学者将其归入西科。笔者认为两者共有的近祖特征,并不能支持它们更近的亲缘关系,而且古猪类缺乏典型西类的近裔特征,因而支持将Pala?
Describes the late-Eocene epoch-forming Eocene epoch-type porphyry fossils discovered in the Baise and Yongle basins of Guangxi. The earliest known pig superfamily fossils, greatly enriched the early Asian pigs, to understand the global evolution of pigs has an important value. The material of Guangxi was identified as two new genera: Eocenchoerus savagei and Huaxiachoerus guangxiensis, a new species of Siamochoerus viriosus and an undetermined species of the genus Tayassuidae genus. et sp. indet. Coupled with the published single-tip brigade Odiochoerus uniconus, a total of five Eocene pig fossils were found in the Baise and Yongle basins. The new genus Eocenchoerus has a simple molar structure that is similar to the original paiaeochoerid but is classified as a porcine by virtue of its pronounced heel. The very primitive form of molars of early stage boars demonstrates that the origin of the swine family is no later than that of Palaeochoeridae and Tayassuidae. Ancient pigs in the old continent have long been considered closer to the tayassuid of the New World, and most scholars categorize it as belonging to the Western Division. The author believes that the common ancestral traits shared by both do not support their closer relationship and that the ancient pigs lack the ethnic characteristics of a typical western species and therefore support Pala?
