Cretaceous Footprints in Bonfim: Dinosaur Tracks and Ancient Amazonian Flora Revealed

A groundbreaking find in the Brazilian Amazon has offered researchers an unparalleled glimpse into Earth's ancient history. On October 27, 2025, experts from the Federal University of Roraima (UFRR) formally confirmed the identification of fossilized dinosaur tracks within the municipality of Bonfim, located in the state of Roraima. This monumental discovery expands the known paleontological record of South America and underscores the dynamic geological shifts that continually mold our planet.

Dating back approximately 110 million years, these remarkably preserved impressions originate from the Cretaceous period. They provide tangible proof of a thriving, diversified ecosystem that once existed here, featuring the passage of both immense herbivorous creatures and smaller, predatory species. Although these traces were initially observed in sandstone outcrops as early as 2011, the rigorous process of official validation and comprehensive study was only recently concluded. This lengthy confirmation process illustrates how even seemingly static environments can conceal profound evidence of ancient historical epochs and great historical transformations.

Adding significant scientific weight to the discovery is the concurrent finding of ancient fossilized flora at the site. This collection includes detailed impressions of conifers, various ferns, and early flowering plants. By analyzing these botanical remnants, researchers can accurately reconstruct the region's prehistoric tropical ecosystems, effectively visualizing the environment inhabited by these Mesozoic behemoths. Understanding these past biological communities is critically important for appreciating the inherent complexity and delicate balance of modern natural systems.

Leveraging the insights gained from this paleontological breakthrough, the UFRR scientific team is actively working to boost environmental literacy and awareness. A key component of their strategy involves establishing a dedicated geological park within Roraima. This ambitious project is designed not only to safeguard the exceptional nature of the site but also to foster scientific tourism, thereby promising a harmonious interaction among researchers, the local populace, and incoming visitors.

The Bonfim discoveries bridge a critical gap in our comprehension of the life forms that thrived in this area long before the current landscape took shape. This context is enriched by the region’s broader geological narrative, notably the proximity of Mount Roraima, which stands as the most ancient formation of the Guiana Shield. While the mountain itself does not share a direct chronological link with the Cretaceous tracks, its immense, monumental presence provides a powerful visual metaphor for the vastness of geological time, reminding us that every epoch in Earth’s chronology was populated by intricate and robust forms of existence.
