Fossil assemblages may provide evidence for local environmental conditions that also influenced deposition of potential reservoirs and source rocks. For example, reefs are formed by a community of interacting species that live together under the same conditions. Communities of terrestrial organisms normally are transported and concentrated into fluvial or lacustrine deposits and are mixed with aquatic organisms. Marine organisms may also be transported, and species from different communities may be mixed by storms and other currents. (For more information on depositional environments, see [[Lithofacies and environmental analysis of clastic depositional systems]] and [[Carbonate reservoir models: facies, diagenesis, and flow characteristics]]).
