Trace fossils
Trace fossils are the product of biogenic processes that have affected mainly sedimentary deposits. Their recognition and interpretation, in conjunction with primary physical sedimentary structures, provide valuable additional information for the interpretation of sedimentary processes, genetic sequences and paleoenvironments. Owing in part to their biological affinities, biogenic structures are characterized to some extent by a complex terminology; however, if perceived in the proper manner, that terminology should not inhibit the sedimentologist in the observation, description and, utilization of biogenic structures for a more complete interpretation of the genetic aspects of sedimentary deposits.
Trace fossils occur in sediments deposited in environments ranging from sub aerial continental to deep marine. Trace fossil in freshwater, continental deposits are group into what is called the ‘Scoyenia ichnofossils’. This ichnofacies is rather non-distinctive, consisting of a low-diversity suite of invertebrate and vertebrate tracks, trails, and burrows (Ekdale, et al., 1984). Trace fossil are not true bodily preserved fossils, but are silly biogenic structures that originated through the locomotion, feeding, burrowing or resting activities of organisms.

trace fossils and burrows
Trace Fossils and Burrows Trace fossils are non-body remains indicating the activity (behaviour) of an organism. They can represent plants or animals.

trace fossil definition from answers com
Trace fossils contrast with body fossils, which are the fossilised remains of parts of organisms' bodies, usually altered by later chemical activity or mineralisation.

what are trace fossils?
Trace fossils represent the activities of ancient animals. There are two main types of fossils: body fossils and trace fossils.
