FUTURE PAST

Digital prints, 2001

This series considers global warming and the environment. Represented are images of cicada shells, pollinated fossils, and foraminifera. Key to the work are foraminifera microfossils; any of a large group of single-celled (usually microscopic) eukaryotic organisms, such as amoebas, ciliates, flagellates and sporozoans. They can be used to determine the age of sedimentary strata. As a result, the presence of certain foraminifera and pollinated fossils in limestone offer clues to corporations whose purpose is oil exploration on where to seek fossil fuels. Thus, they are actively sought after by fuel industries. They are also important bioindicators in coastal environments, including indicators of coral reef health.

Note: The cicadas were collected by colleagues from various parts of the United States.
