Cretaceous System is widely represented in South America. ?Conchostracans?are best represented with 47 early Cretaceous species and only 5 Late Cretaceous ones. Its warm climate with rainfall and marked seasonality allowed thedevelopment of the ?conchostracan? populations. This information showsthat more detailed analysis between climate and ?conchostracan? records isneeded to reconstruct environments in the Cretaceous times.
