Brazilian archaeologists uncover ancient humans’ link to dinosaur fossils

In the remote agricultural region of Serrote do Letreiro in Eastern Brazil, researchers have uncovered a remarkable archaeological and paleontological convergence that offers new insights into early human interaction with prehistoric remnants.

Recent drone surveys revisiting a site first studied in 1975 have revealed petroglyphs—stone carvings estimated to be up to 9,000 years old—strategically positioned mere inches from dinosaur footprints dating back around 66 million years, Caliber.Az reports via foreign media.

The dinosaur tracks, believed to be from the Cretaceous Period, sit just two to four inches away from the intricate petroglyphs, suggesting a deliberate placement by the ancient artists. “The individuals who crafted the petroglyphs were acutely aware of the footprints, likely selecting the location precisely because of them,” said Leonardo Troiano, an archaeologist from Brazil’s National Institute of Historic and Artistic Heritage.

Dating indicates the site was occupied by small seminomadic hunter-gatherer groups between 9,400 and 2,620 years ago. While stylistic differences among the carvings suggest multiple contributors over time, all appear to orbit the dinosaur footprints, highlighting a shared cultural or symbolic understanding.

The significance of this site extends beyond simple coincidence. The Coordinator of Cooperation and Promotion at Brazil’s National Historic and Artistic Heritage Institute stated that the petroglyphs “reveal a deep reverence for fossil tracks among Brazil’s ancient, indigenous communities.” These engravings may represent more than decoration, possibly serving as a cultural or spiritual link to the prehistoric landscape.

Troiano emphasized the importance of the site as “evidence of our species’ journey and the ongoing human engagement with the natural world and its fossil record.” He added that the site “bridges ancestral symbols with the fossil record” and “highlights the connection between native people and fossils,” enriching our understanding of ancient perceptions of time and nature.

The interdisciplinary team leading the project includes Troiano, paleontologists Aline Marcele Ghilardi and Tito Aureliano, and archaeologist Heloisa Bitú. Their work not only advances academic knowledge but also preserves a vital part of Brazil’s cultural heritage.
