Biber Deresi is an open-air site located on the Assos/Behram, Çanakkale coast, associated with river systems and raw material sources. The site’s particular importance is owed to the discovery of the most extensive Lower and Middle Palaeolithic assemblage yet identified on the Aegean coast of Türkiye. The lithic assemblage is characterized by a significant number of large cutting tools, including handaxes, cleavers, and trihedral picks, as well as pebble core tools, which are predominantly chopping tools. Flakes produced from both unprepared and prepared cores predominate. It is evident that, during the Pleistocene low sea level period, the region had a continuous connection with Lesvos and, via the eastern Aegean islands, with mainland Greece. Biber Deresi is identified as a key site, facilitating hominin movement and communication between Asia and Europe, and providing a novel contribution to the Palaeolithic map of the Aegean.

Nery Delgado was a key figure in the development of archaeological methods applied to prehistoric sites in Portugal within European archaeology at the end of the nineteenth century. He was the first in Europe to use a grid in his 1879–1880 excavation at the Casa da Moura cave (Óbidos, Portugal). The grid divided the cave into twenty-eight sectors excavated independently and, in each, all archaeological and bioanthropological finds were documented and marked with labels recording depth and excavation units. The 3D information obtained by Nery Delgado features among late nineteenth-century attempts at recording contextual data, a precursor of archaeological methods of data gathering that are used worldwide today. Nery Delgado was, thus, a pioneer of contemporary archaeological excavation methods.
