【摘要】 <正> 从1964年起,我们整理了周口店北京猿人化石产地(周口店第一地点)的粪化石,以及我国其他化石地点,如广西柳城巨猿洞里的一些同类材料。在整理工作中,清理出周口店遗址现有的粪化石,除破碎的外,约有1500枚左右。在遗址目前发掘到达的40米厚的堆积物剖面中,它们和其他化石一起,占据了从底部到上部的好几个层位,如第10层,第8—9层,第6层等。这些标本,有时密集成层,也有的是较零星的分布的。更多还原

【Abstract】 We have recently started to investigate a large collection of coprolites collected some 20—30 years ago from various stratigraphical layers of Locality 1 of Choukoutien fossilifer- ous deposits(or Choukoutien Sinanthropus locality).Compared with the excretions of carnivorous and omnivorous mammals now kept in Peking Zoological Garden,a great number of our specimens in hand(more than 1500 pieces)seems to be comparable in shape with those discharged by the living Hyaena or Crocuta.One largest sample in the present collection appears to be the dung of a kind of bear(?Ursus spelaeus). It is interesting to note that on some fractured specimens there are some imprints of leaves,seeds and stems of certain plants.Determined by Prof.Hsu Jen and Miss Tao Chun-jung,one imprint of leaf represents Lespedeza floribunda Bunge(Pl.Ⅰ,Fig.2b), which is still living in North China and whose pollens were observed in the Choukoutien deposits by Sun.We also find in both the excretions of Hyaena and Ursus(Pl.Ⅱ,Fig. 4)the imprints of the entire endcarps of Celtis barbouri,which was known since long time ago(Chaney,1935).Other imprints of leaves,stems and fibrous matter of plants are difficult to be determined.更多还原
