The taphonomical study of a sub-fossil sample from layer 1a of the Monte di Tuda site (Holocene, Corse) has been undertaken following Andrews (1990) method. The very high fragmentation percentage of this assemblage has lead to the creation of new fragmentation categories for long bones. The skull remains of Murinae and Crocidurinae have been treated separately which gives interesting results about their differential preservation. Traces of digestion have been observed through the use of S.E.M examinations, their proportions and their weak grades correspond to category 1 of predator after Andrews (1990) and more precisely to Tyto alba. Post predation alterations are recognized (among them trampling, root marks, weathering, soil corrosion). Comparison with modern owl pellets assemblage from Monte di Tuda site and from others Corsica sites confirms the different proportions of the faunal lists of the level 1a.
