These arthropods include Eichstätt, decapod crustaceans, stomatopods, supposed mysidaceans, and limulids.

The scientific changes were not exist at the Paris Muséum and fossils were supported by some very important French professors distributed into different collections: geology, such as Barthélemy Faujas de Saint-Fond (1741- botany, mineralogy. In 1853, when the chair of 1819), Anselme-Gaétan Desmarest (1781-1838), palaeontology was especially created for Alcide Alexandre Brongniart (1770-1847) and above all d’Orbigny, numerous professors of the Museum Alphonse Milne Edwards (1835-1900).
