Preservation of traces

Abstract

Study on the preservation processes of modern traces is important as it enhances their chances to be fossilized in due course. It is the first step towards fossilization. Modes of preservation decide the resultant architecture of the trace fossils. Depositional environments, besides many post depositional physical and chemical processes, decide the mode of preservation of modern traces. Preservation potential of a structure in a given environmental setting decides its availability in rock record as trace fossil. Various aspects of preservation potential of the modern traces are addressed here. The preserved Kalna and Nabadweep traces have been identified ichnotaxonomically. Styles of preservation under episodic, steady and high energy conditions of deposition are also discussed.
