In 1951 two men found its way to Dom Pedrito, a town in southern Brazil, to handle geological mapping of the pampa, or low grassland. There they found a rocky hill filled with the remnants of a wetland ecosystem that existed some 260 million years back.
Through the Permian period, when the majority of Earths landmass was still bound up in the supercontinent Pangea, this section of what’s now Brazil was covered in vascular plants like horsetails and ferns, and a nearby body of water contained various aquatic creatures. This ecosystem existed shortly before a mass extinction dealt a significant blow alive on the planet and set the stage for the rise of the dinosaurs, making the fossil site a substantial paleontological find.
However the researchers didnt leave a description of the precise located area of the extraordinary site that they had unearthed, a three-acre patch among about 450 acres of land. In order time passed, and the dirt roads that they had followed decades ago were replaced by paved highways that traced different routes, the website was lost to science.
