Recovering data from historical collections: stratigraphic and spatial reconstruction of the carnivoran record from the Late Pleistocene Equi cave (Apuane Alps, Italy).

Equi Terme is a hamlet located in northern Tuscany, in Apuan Alps regional Park. An outstanding fossil vertebrate collection housed in Florence is the result of excavations in the Equi cave and shelter during the period 1911e1919. This faunal assemblage (associated with Mousterian artefacts) may be correlated with the middle of MIS 3. All of the specimens recovered at Equi early in the last century were collected with attention to their stratigraphical positions. Detailed field annotation for nearly every specimen allowed us to organize them and attempt a stratigraphical and spatial reconstruction of the fossiliferous deposits. We present the results of the study of the spatial and stratigraphic distribution of the carnivoran species in the Equi cave and shelter, and re-evaluate the taphonomic agents of accumulation and the fossil distribution within the stratigraphic record. In particular, we evaluated the distribution of Panthera pardus, which, unusually for Europe, is abundant in the Equi cave assemblage. This analysis highlights the importance of the re-evaluation of historical collections and allows for future comparisons with data from more recent excavations at the Equi site. The analysis also provides an account of the distribution of carnivorans throughout the stratigraphic record. The constant presence and the predominance of leopards and wolves over lions and smaller carnivorans, allow for evaluations of their ethology and may be related to a short period of sediment accumulation.
