东渨洼陷形成于地洼阶段余动期。早第三纪陆相沉积发育,富含油气资源。在始新世至渐新世地层中产有丰富的陆相遗迹化石。经初步鉴定,主要分为居住迹(Domichnia)、觅食迹(Pascichnia)、爬行迹(Repichnia),逃逸迹(Fugichnia)、进食迹(Fodinichuia)、停息迹(Cubichnia)及其过渡类型。Feeding structure)、居住构造(Dweling structure)、逃逸构造(Escape structure)等类型,本文中描述了其中一部份化石。这些陆相遗迹化石的发现,为该区沉积学、古生态学和构造活动特点的研究提供了新的材料。
Dongji depression formed in the depression period of depression. Early Tertiary continental deposition, rich in oil and gas resources. In the Eocene to Oligocene strata in the production of rich terrestrial fossils. After preliminary identification, it is divided into Domichnia, Pascichnia, Repichnia, Fugichnia, Fodinichuia, Cubichnia and their transitional types. Feeding structure, Dweling structure, Escape structure and so on. Some of these fossils are described in this article. The discovery of these terrestrial trace fossils provides new materials for the study of the sedimentology, paleoecology and tectonic activities in the area.
