Fürsich. Franz Theodor 1978 07 IS: The influence of faunal condensation and mixing on the preservation of fossil benthic communities. Lethaia, Vol. 11, pp. 243–250. Oslo. ISSN 0024–1164.

Condensation phenomena caused by environmental, biotic, or diagenetic factors are widespread in the fossil record, especially in shallow shelf sediments, and may alter the composition of ancient communities. Even without large-scale transport being involved, often only time-averaged seres will be available for palaeosynecological studies. This should be kept in mind when community analysis of such shell accumulations is attempted.
