潟长沙大地构造研究所中原油田课题组、在对华北地区东濮凹陷沉积建造的研究中,于下第三系地层中发现了较为丰富的遗迹化石。依其形态特征与造迹生物的行为习性分类,主要有:停息迹(resting traces)、爬行迹(crasting traces)、觅食迹(grazing traces)进食构造(feeding structures)、居住构造(dweling structures)、逃逸构造(ecaspe stuctures)等六大类(大部份为新属,全部为新种)。
In the research on sedimentary construction of Dongpu Depression in North China, the Zhongyuan Oilfield Research Group of Changsha Institute of Tectonics has found abundant trace fossils in the Lower Tertiary strata. According to their morphological characteristics and the behavioral habits of the pathogenic organisms, there are mainly resting traces, crasting traces, feeding structures for grazing traces, dweling structures, , Escape structure (ecaspe stuctures) and other six categories (most of the new genus, all new species).
