The study presented here aims at finding new methods to improve the accuracy of palaeoecological and biochronological studies and describe the palaeoenvironmental and chronological settings of the Riversleigh fossil deposits. One of the methods developed in this thesis, Minimum Sample Richness (MSR), determines the minimum number of species that must be present in a fauna to allow meaningful comparisons using multivariate analyses. Using MSR, several Riversleigh localities were selected for a palaeoecological study using the cenogram method to determine the palaeoenvironment during the Oligo-Miocene. Finally, the Numerical ages method was used to refine the relative ages of the Riversleigh localities and a re-diagnosis of the Riversleigh Systems is proposed.

LA?tude pr?sentée ici vise C trouver de nouvelles m?thodes pour am?liorer lDe9actitude des ?tudes pal?o?cologique et biochronologique et d?crire les param@tres paléoenvironnementau9 et chronologi:ue des localit?s de Riversleigh. LDune des m?thodes d?velopp?es dans cette th@se, Minimum Sample Richness (MSR), d?termine le nombre minimum dDesp@ces qui doivent Etre pr?sents dans une faune pour permettre des comparaisons significatives avec les analyses multivariées. En utilisant MSR, plusieurs localit?s de Riversleigh ont ?t? choisies pour une étude pal?o?cologique utilisant la m?thode des c?nogrammes permettant de d?terminer les paléoenvironnements pendant l‘Oligo-Mioc@ne.
