Ancient Brazilian Petroglyphs Hint at Human Awareness of Dinosaurs

Petroglyphs found near dinosaur footprints in Brazil suggest that prehistoric indigenous people may have been aware of and interested in the footprints, although it's unclear if they knew about dinosaurs. The carvings, dating back between 9,400 and 2,620 years, display geometric shapes and may have been created during communal gatherings, possibly with the use of psychotropic plants. The unprecedented clarity of the association between the petroglyphs and dinosaur prints at this site could have significant implications across paleontology, archaeology, and cultural heritage studies.
