Taphonomy is a tool widely used by zooarchaeologists to understand the strategies of prehistoric human subsistence. In assemblages where the preservation of the bone surface is poor, it is necessary to apply different types of methods and analysis to better understand and interpret data. The archaeological site of Visogliano has one of these assemblages. The site is a Middle Pleistocene shelter located in Trieste Karst, north-eastern Italy, that can be dated to the 350–500 kyr time span. Human remains, lithic industry and an extensive faunal assemblage have been excavated in the past. This is the first taphonomic approach carried out on faunal remains from this archaeological site. From an exploratory work, a selection of three layers was studied and analysis were carried out. Our results demonstrate that the bone surface is greatly altered, mostly due to concretions and the action of water. And finally, corroborates positively in the hypothesis of an involvement between hominins and faunal remains, through possible butchery mark
