Paleocoast models developed by specialists from the Patagonian Institute of Geology and Paleontology (IPGP-CONICET) indicate that 11,000 years ago the sea was located nine kilometers from the current coastline.
Notes on verification
The claim is repeated verbatim across multiple Argentine outlets but all trace back to a single CENPAT-CONICET press release. Independent corroboration exists for the underlying research program (paleocoast/sea-level modeling by Zangrando and Ponce, 2025, referenced in a ScienceDirect paper) and for the age of the associated human remains, but the specific '9 km' figure itself was not independently verifiable outside press-release-derived sources.
