This Rusophycus specimen is part of an ongoing research project of the Department of Invertebrate Paleontology at the CMNH. This Rusophycus is an ichnofossil, or trace fossil, meaning that it displays evidence for movement and existence of an animal and not the actual thing, similar to a footprint.Ichnofacies can provide information about water depth, salinity, turbidity and energy. In general, traces found in shallower water are vertical, those in deeper water are more horizontal and patterned. [1] This is partly because of the relative abundance of suspended food particles, such as plankton, in the shallower waters of the photic zone ...
