Rio Bonito Formation, Geological formation in São Paulo, Brazil
The Rio Bonito Formation is a geological layer in southern Brazil's underground consisting mainly of sandstone, siltstone, and clay deposits. These materials stack in layers that show how the region was shaped over time.
This formation developed during the Permian period when South America was part of a large ancient continent and sea covered the land. These deposits remained buried underground for millions of years, recording a distant past.
Scientists extract fossils of Glossopteris flora from this formation, providing evidence of plant life that existed during the Permian to early Triassic periods.
The rock of this formation is accessible to scientists and geology enthusiasts who want to study underground layers. It is best to contact local museums or universities beforehand, as they provide access to core samples and collections.
These layers contain fossils of ancient plants that show a completely different climate existed here hundreds of millions of years ago. The plant remains help researchers today understand past climates and investigate the effects of climate shifts.
