As part of a recent study published in the journal Scientific Reports, a Brazilian multidisciplinary team has shed light on an intriguing discovery in Serrote do Letreiro, in the municipality of Sousa, Brazil. This region, known for having preserved dinosaur footprints, today reveals a link between dinosaurs and prehistoric humans.

The study reveals that petroglyphs dating back 3,000 to 9,000 years, symbolic designs carved into a natural rock surface, may have been inspired by dinosaur footprints preserved in the same area. Although it has been difficult to precisely identify the types of dinosaurs that left these tracks, researchers suggest that they could belong to ornithopods, theropods and sauropods, having roamed the area 40 million years ago. years. The close relationship between petroglyphs and dinosaur footprints is remarkable. This suggests that prehistoric artists were not only aware of these imprints but also probably fascinated by them, to the point of incorporating these elements into their art and perhaps even into their rituals or ceremonies.
This study also highlights the hypothesis that the creators of these petroglyphs may have used hallucinogens. This theory is based on the similarity between artistic motifs and visions commonly reported by users of such substances in the modern era.
The importance of this discovery lies not only in its contribution to the understanding of the interaction between early human beings and their environmentbut also in the insight it offers into how dinosaurs and their footprints may have influenced the cultures and beliefs of ancient people.
