Ostracode

The ostracode S are Arthropode S Crustacé S whose body is entirely locked up in a carapace made up of two valves, generally limestones, articulated dorsalement. Only the ends of some appendices leave this carapace ventralement when the animals move on the substrate or when they swim in the water column. The ostracodes occupy all the seamen circles and of fresh water. Approximately 7000 current species were described. The species Fossile S are excellent stratigraphic indicators.

Their size varies from 0,3 mm to approximately 5 cm (0,5-3 mm for the majority of the species).

Their stratigraphic distribution goes from the Ordovicien to our days.
