What began as a kayaking trip along the Jatapu River in Caroebe, southern Roraima, became an unexpected journey into the past for fisherman Marcell Reis, who identified at least 30 rock engravings that may be as old as 3,000 years BC. The engravings are spread across different sites along the river, typically found along the banks, and their discovery sheds light on the region's ancient history.

Marcell, who is also a military firefighter, noted that he only began observing the engravings a week after his nine-day expedition in January, which he undertook with his wife. He described following a remote stretch of the river near its source and encountering the drawings at various points, suggesting that the area might be rich in prehistoric art. The discovery is significant not only for its archaeological value but also for understanding cultural and historical narratives linked to the indigenous populations of the region.

The implications of Reis's findings are profound, as they highlight the interplay between nature and history, particularly in remote areas like Roraima, where modern exploration continues to unveil the past. Such discoveries can drive interest in preservation efforts or initiate further archaeological inquiries, emphasizing the importance of safeguarding such cultural heritage for future generations.
