The paleoenvironment influences trace-making behavior significantly, and progressively more evidence shows that this behavior follows scale-invariance properties. In this study, we focused on the definition of behavioral complexity in the trace fossil Zoophycos to explore its paleoenvironmental significance. Firstly, the fractal topography in Zoophycos was …turbated textures for more than 20 types of trace fossils, including Zoophycos, Chondrites and Paleo-dictyon,inwhichD varies around the values of [1.45,1.8]. In this research, fractal geometry wasThe trace-fossil record provides a wealth of information to track the rise and early evolution of animals. It comprises the activity of both hard- and soft-bodied organisms, is continuous through the Ediacaran (635–539 Ma)– Cambrian (539–485 Ma) transition, yields insights into animal behaviour and their role as ecosystem engineers, and allows for a more …So ZOOPHYCOS is a trace fossil. The names, Chondrites scoparius and Cancellophycus (both described between 1858 and 1873 from studies of the surroundings of Lyon, in France), and other specimens, such as Spirophyton (which were collected in the United States), were originally considered as synonyms of Zoophycos. ...

An association …Chevron-ridged or indented markings are usually trace fossils, also called ichnofossils. Trails of worms, snails, and other invertebrates can be preserved as fossils and leave many different kinds of shapes. Often the shape is the same color and texture as the surrounding rock.
