Classical Site: Damery - Fleury-la-Rivière

A classical site for (micro-) paleontological research is the area Damery - Fleury-la-Rivière in the Paris Basin. It is famous for rich fossil beds of Lutetian Age (48.6 - 40.4 mya). In the 19th century pre-evolutionist Jean-Baptiste Lamarck (1744-1829), the author of many first descriptions of species Alcide Dessalines d'Orbigny, Olry Terquem (1797-1886) and others worked on fossil foraminifera of the Paris Basin.

The foraminiferal fauna indicates shallow water, warm marine conditions such as found today in the Red Sea: a great variety, rich ornamented and big foraminifera, a substantial part being Miliolids.






Ornamented Miliolid: Miliola prisca (Terquem, 1882)
















Unornamented, rather large Miliolid: Triloculina trigonula (Lamarck, 1804)

















Trochulina turbo (d'Orbigny, 1826), umbilical side















Trochulina turbo (d'Orbigny, 1826), spiral side
