摘　　要：本文是在对贵州石炭系地层岩相古地理研究过程中，采集了大量遗迹化石，共１１属（新属４）１１种（含未定种）。根据这些遗迹化石的古地理分布特征，建立了贵州石炭纪遗迹化石群落与岩相古地理之间的关系。同时结合石炭系地层中大量的Ｚｏｏｐｈｙｃｏｓ产出层位岩相特征以及国内外已有Ｚｏｏｐｈｙｃｏｓ产出层位岩相古地理情况，总结出Ｚｏｏｐｈｙｃｏｓ的地史时期古地理变迁史：即－Ｐ为浅海环境（包括内陆棚、台沟、台地、滨海等）；Ｔ—Ｊ为浅海－深海过渡的半深水环境；Ｋ—Ｅ为深水环境。Trace fossils are abundant in the Carboniferous strata, especially in those representingcarbonate platform and platform ditch. So far, the authors.have discovered some particulartrace fossils, such as ZOOPhycos, Chondrites, Parascalaritubus Planoll'tes, paradendnOPhycus,Laminationl'chnus, SPirorhaphe, Lophoctenium, SPrirOPhyton, M u d fe ed in g - b u r ro w ep ich 'us.In addition, the authors have studied the distribution of trace fossil ZOOPhycosthroughout the geologic historical time since its initial occurence in strata. The resultshows that ZoOPhycos existed in shallow water environment during the period of the Cambrian to Permian, in the transitional envrionment between shallow and deep water duringthe Triassic to Jurassic period, and in deep water and bathyal environment after the Cretaceous to Cenozoic time.We suggest, then, that ZOOPhycos is still of significance to factes indicator in the different geological period.
