在遗迹化石中,Zoophycus Massalongo(动藻迹)是一类发现较早,地层和地理分布相当广泛的生物成因构造;据文献记载,化石记录见于奥陶纪到第三纪世界各地的海相地层。由于 Zoophycus 形态构造比较特殊,个体较大,往往斜穿地层层面,很难采到完整的化石标本,因此,对其造迹生物、形成机制,迄今还没有完全解决。对其沉积环境以及分类都还缺乏系统整理和进一步的工作。我国各时代地层中的 Zoophycus,过去更无人问津。作者发现该类遗迹化石在石炭纪煤系地层中分布相当普遍,且对沉积环境具有一定的指示意义。文内研究的遗迹化石分别采自下列各地:
Among the trace fossils, Zoophycus Massalongo is a type of biogenic genetic structure that was found earlier, with stratigraphic and geographically extensive distribution. According to the literature, the fossil record was found in the marine strata of Ordovician to Tertiary world . Because Zoophycus is rather special in shape, larger in size and often diagonally through the strata, it is very difficult to obtain complete fossil specimens. Therefore, it has not completely solved the mechanism of its formation and formation. There is still a lack of systematic collation and further work on its sedimentary environment and its classification. Zoophycus in the strata of various periods in our country was even more neglected in the past. The authors found that the type of trace fossils in the Carboniferous coal measures strata distribution is quite common, and the sedimentary environment has some indication. The trace fossils studied in the text are taken from the following places:
