SYSTEMATIC AND TAPHONOMY OF A FAUNULE OF THE DECAPOD CRUSTACEANS OF THE MARIA FARINHA FORMATION (PALEOCENE), PERNAMBUCO STATE, BRAZIL. The study of 52 decapod crustacean specimens of the Maria Farinha Formation, collected at the Poty Quarry, district of Paulista, State of Pernambuco, revealed the occurrence of the Necrocarcinus sp. and Costacopluma nordestina Feldmann & Martins-Neto. The fossiliferous association is characterized by allochem remains in carbonatic rocks. They occur mostly dislocated and fragmented, indicating high energy in the depositional environment during the burial event. About 89% of taphocoenosis is represented by isolated thorax (dominantly), chelipeds articulated with the thorax, and isolated dactylus, defining the normal burial position. The remaining 11% occurs as articulated chelipeds with the thorax and sternum, curved upwards, sugesting the escape position. The preservational features indicate that the deposicional environment was extremely variable in energy, intercalating high energy periods, in which dead organisms remains were fragmentated, with low energy periods, in which the remains were accumulated, deposited and buried. The preservation in escape position indicates that the burial happened during the quick changes between low and high energy periods, suggesting a coastal environment, under the sea level oscillations. This hypothesis is corroborated by taxa found in the environment here identified, corresponding to members of the Goneplacidae and Ocypodidae families, typical of swamps.
