La Cansaladeta is a site located in a narrow passage dug out by the Francolí River in the Pre-littoral Catalan range (NE Iberia). The archaeological deposit lies on top of a +45–50 m fluvial terrace, and contains a rich Middle Pleistocene stratigraphic succession in which 10 archaeological layers have been identified. Here, we present the description of the sedimentary succession of the site, the available chronological framework (including TL, TT-OSL, and ESR/U series ages, as well as biostratigraphical information), the characteristics of the lithotechnical and faunal assemblages, as well as the first interpretation of the human occupations at the site. Three main occupation phases have been differentiated. The oldest archaeological layers are embedded in a palaeosol formed on a clayey layer that contains limestone fragments detached from the shelter's wall and roof. During the second phase, low energy fluvial sediments coming from lateral river floods were deposited and sealed the archaeological layers. After a transitional phase, the upper layers appear to be derived from slope sediments. Numerical dating yielded internally consistent dates of 380–400 ka for the sequence. However, the study of the fossil assemblages potentially suggest a tentative early Middle Pleistocene age for the lowermost horizons. The rich technological record is made up of several local raw materials, especially chert but also schist, quartzite, quartz and other minor rocks. Knapping sequences seem to be autochthonous, as all the elements and size-categories of the reduction sequence are present, and refits are common. Techno-typological features observed along the sequence are not very diagnostic, however the lower layers include some Acheulean forms among the large shaped tools, restricted variability among the small retouched tools (mostly denticulates) and a virtually absence of prepared cores. The faunal assemblage is scarce and appears strongly altered. Only the lower layers have provided fruitful information. Although neither combustion areas nor structures related to fire-use have been documented to date, heat damage has been repeatedly recorded on both lithic and faunal remains. This may point to systematic fire use within the archaeological sequence. The data provided by the ongoing excavations at La Cansaladeta provide new insight into the early human settlement history of northeast Iberia to be reconstructed. Combining these data with those coming from the close site of Barranc de la Boella, enable us to better reconstruct the timing, nature and context of early human occupation in the region.
