This empty test is beginning to show signs of decay. The study of the process of decay is called taphonomy; understanding the processes that cause certain changes in foraminiferal tests after death is very important for the reconstruction of paleoenvironments. Individual isolated from the Hamble estuary, southern England. Image courtesy of Dr. Elisabeth Alve, University of Oslo. Citation: Alve, E. and Murray, J.W.

This test, which no longer contains a living foraminiferan, is beginning to decay. The small chambers at the top of the test are gone, leaving a spiral of holes where they once were.
