Trace fossils, or ichnogenera, is one of the most active areas of paleontology today and play a vital role in modern sedimentary geology. Back to "Fossil Home" Pemberton, S. G., and MacEachern, J. Paleontological resources, or fossils, are any evidence of past life preserved in a geologic context. Trace fossil assemblages are far from random; the range of fossils recorded in association is constrained by the environment in which the trace-making organisms dwelt. Fossils are the remnants or trace of an organism of a some earlier geologic age, such as a skeleton or leaf imprint, embedded and preserved in the earth’s crust. The first trace fossils are very simple trails: The earliest clear indications of animals are trace fossils from about 570 Ma – structures, such as trails, that record animal activity. Palaeogeography, Palaeoclimatology, Palaeoecology, 485 455-465. Studies of sedimentary rocks offered a glimpse at life at the earth’s surface, and trace fossils in pillow lavas offered evidence for a potential deep biosphere back in time to the Paleoarchean.
