摘要: 济阳坳陷下第三系,局部含有一些海相起源生物的属种.他们具低分异度,强形变的特征,与典型陆相生物共生,存在于水进初期的碳酸盐-石膏沉积系列中,又随水体加深而消失.他们的出现代表了大型封闭古含盐湖生物群特色,而生物群生活的水体,却未见任何与海相连的通道,他们的存在不能作为海侵的证据.

Abstract: Paleogene in the Jiyang depression,Shandong province,contains a number of marine an-cestry genera and species which are characterized by a low diversity and very strong variability and coexist with some typically continental organisms in a carbonate-gypsum depositional system at the begining of the lacustrine transgression and disappear with the increasing ofwater-depth.Therefore,their occurrance represents a biota in a large-closed Saliferous paleo-lake where no communication with the ancient sea has been found.Their existence can not be considered as a criteria of sea transgrassion.
