Explanation:

Previously existing organisms leave behind evidences of their existence in form of remains that has been collected and mineralized called FOSSILS. However, the fossils of an organism (plant or animal) can either be a trace fossil or an original remain/body fossil. The difference between the two are as follows:

- An original remain is the fossilized body or body part of an organism that once existed. For example, bones, shells and fossilized leaf are examples of original remains.

- On the other hand, trace fossils refers to any form of evidence, apart from the organism's body, that suggests the presence of that organism in that particular place at a particular time. Trace fossils are said to be illustrate presence of life but indirectly (via their activities). Examples of trace fossils are burrows, tracks, marks etc.
