The continued washing, sorting, and identification of middle Eocene ( approximately 45Mya) primates from the Shanghuang fissure-fillings (Jiangsu Province, China) have produced additional hind limb elements. All are isolated elements. The strepsirhine hind limb elements include a first metatarsal and a talus, which are appropriate in size and morphology to pertain to Adapoides troglodytes. Adapoides is interpreted as a quadrupedal-climbing (nonleaping) primate with similarities to living lorises and the fossil primate Adapis. The haplorhine hind limb elements are estimated to span a range of adult body sizes from tiny (17g) to small (200g). Included among the new sample of haplorhine hind limb specimens is the smallest primate talus reported thus far. These new postcranial specimens expand our understanding of early haplorhine hind limb anatomy and demonstrate additional similarities between Shanghuang eosimiids and other anthropoids.
对来自中国江苏省上黄裂隙填充物中始新世(约4500万年前)灵长类动物的持续清洗、分类和鉴定,又发现了一些后肢骨骼。所有这些都是孤立的骨骼。湿鼻灵长类动物的后肢骨骼包括一根第一跖骨和一块距骨,其大小和形态与洞猿猴(Adapoides troglodytes)相符。洞猿猴被解释为一种四足攀爬(非跳跃)的灵长类动物,与现存的懒猴以及化石灵长类动物阿氏猴(Adapis)有相似之处。类人猿灵长类动物的后肢骨骼估计涵盖了从微小(17克)到小型(200克)的一系列成年个体体型。在新的类人猿灵长类动物后肢标本样本中,有迄今为止所报道的最小的灵长类距骨。这些新的颅后标本扩展了我们对早期类人猿灵长类动物后肢解剖结构的认识,并显示了上黄始镜猴与其他类人猿之间更多的相似之处。
