Abstract
The origin and preservation of a track are related to many distinct environmental factors, concerning especially the substrate cohesiveness, plasticity, grain size, texture and water content. Then, the environment, through the sedimentation processes, plays a role that enhances the origin and quality of the tracks and their preservation. Three distinct contexts - tidal flats, aeolian, fluvial-lacustrine paleoenvironments, that encompass the majority of fossil footprints occurrences are analyzed. Footprints as biosedimentary structures, due to their close relationships with physical and chemical processes that control their formation, represent an important clue to paleoenvironmental interpretation. The present study is mainly based on the direct examination of ichnosites that allow us to evaluate the aspects of Mesozoic tracks from different regions of the paleocontinent Gondwana, currently correspondent to Argentina, Australia, Bolivia, Brazil, Congo, Iran, India, Madagascar and Morocco as sedimentary structures and their use in paleoenvironmental interpretations.
