Researchers conducted an extensive study of bone artifacts from 26 Paleolithic caves and rock shelter locations in the Cantabria area of Spain and southwestern France.
173 work (a) and raw (b) taxonomic identification of bone objects: (1) blank, Tito Bastilo, sperm whale. (2) A launch point with a huge base, Islitz and a blue whale. (3) Lassempouy, Fin Whale; (4) Rascaldas, a sperm whale; (5) A launch point with a giant base, Hermitia and a gray whale. (6) Unclear object, St. Michelle, a sperm whale. (7-10) Santa Catalina, raw fragments of fin whale bones. Image credit: McGrath et al., doi: 10.1038/s41467-025-59486-8.
“The largest creatures on Earth, whales were a vital source of nourishment and materials like oil and bone,” stated Dr. Christa McGrath, the lead author and an archaeologist from the University of Barcelona, along with her co-researchers.
“Hence, they are thought to have been instrumental in the survival of various coastal human populations.”
“Nonetheless, tracing the origins of human and near-human interactions is challenging since coastal archaeological sites are particularly prone to the impacts of rising sea levels, complicating the preservation of evidence regarding early human-mammal relationships.”
The authors examined 83 bone tools from various cave and rock shelter locations around the Bay of Biscay in Spain, along with an additional 90 bones from the Santa Catalina Cave in Biscay province.
Utilizing mass spectrometry and radiocarbon dating methods, they identified the species and age of the artifacts.
The earliest two dates were from the Cantabrian sites of Las Caño and Ergeyo, which dated to 20,200-19,600 and 19,600-19,000 years ago, respectively.
“Our findings show that the bones came from at least five large whale species, with the oldest dating back around 19,000-20,000 years,” mentioned Senior author Dr. Jean Mark Petitillon, an archaeologist at Toulouse-Jean-Jalaise University and CNRS University.
“This provides some of the earliest known proof of humans utilizing whales as tools.”
“Zoomorphometry is an effective method for studying past marine mammal diversity, especially when key morphological features are absent in the bone remains and artifacts.
“We identified gray whales that not only existed in Biscay Bay but are now confined to the North Pacific and Arctic oceans.”
“Moreover, chemical analysis of the bones indicates that the feeding patterns of these ancient whales varied slightly from those of contemporary ones, highlighting potential shifts in behavior and marine environments.”
“This discovery not only enhances our understanding of the early human use of whale remains but also illuminates the role whales held in ancient ecosystems.”
The team’s study is set to be published in the journal Nature Communications.
