Resumen:
Geological studies are fundamental to archaeologists as they provide essential data to understand certain
processes involved in the present archaeological record. Whenworking on marine coastal archaeology, the
information provided by geomorphologic studies with regards to the evolution and dynamics of coastal
marine lines is essential to assess the availability and accessibility of certain marine coastal areas, and their
resources, to human populations of the past. This is also the key to reach correct cultural interpretations.
However, on certain occasions, archaeological information can also offer valuable alternative data for
geologists to reach geological interpretations, for instance when working on the evolution and changes of
coastal sea lines. In this case, spatial and temporal scales must be regarded. This idea is supported on the
experience gained through research done on the Patagonian Atlantic coast at the two archaeological
localities introduced in this paper: Cabo Blanco, where we evaluate models of evolution of the coastline
with a number of radiocarbon dates from excavated sites; and Punta Medanosa, where we discuss the
temporal depth of the formation of the coastal ridges for the mid-Holocene transgression.
