Resumo

URI DE CIMA, PERNAMBUCO, BRAZIL.The results of the study on spatial arrangement, the analysis of marks and the preservation conditions of the giant ground sloth (Eremotherium) remains found in the Lagoa Uri de Cima (Salgueiro, Pernambuco, Brazil), a temporary shallow lake, are presented here.The skeletal elements of the same individual, an adult, found in a restricted area (about 8 m in diameter) and its taphonomic patterns suggest that the animal arrived in the shallow lake as a carcass, and its bones were subsequently spread apart and broken mainly by trampling by other large animals.This taphonomic model also applies to some other Eremotherium individuals found into the "lagoa", but not to all.That means that the sequence of processes affecting the formation of this kind of fossil deposit is generally relatively complex.
