Vertebrate and invertebrate megafossils as well as foraminiferans
and diatoms previously have been reported from the Puente Formation.
Bernhard focuses on protists called foraminiferans
and symbiotic bacteria that seem to help the protists live in extreme environments such as the deep sea.
Nestor (1994) has provided 7-grade estimations of the plankton/benthos ratio in acid-resistant microfossil assemblages (mainly chitinozoans representing the plankton, and scolecodonts, melanoscleritoids, and foraminiferans
representing the benthos).
The two areas provide present-day and post-spill scenarios that show how foraminiferans
may be used to detect the duration needed for bioremediation within a marsh environment.
, coralline algae, corals, brachiopods, bryozoans, worms, and mollusks form structures of shelly calcium carbonate on rocks.
