In 1945, a railway crew cutting a grade north of Uberaba hit bone. The rock they were working through was red Cretaceous sandstone, and the animals inside it had been dead for something between 83 and 66 million years. Word reached Llewellyn Ivor Price, a palaeontologist with Brazil's mineral production department, who came to look and then kept coming back for nearly thirty years. What that accidental roadcut opened was the Bauru Group: a stack of continental sediments spread beneath the Triângulo Mineiro and western São Paulo that holds the most diverse Late Cretaceous archosaur record in Brazil.

The Bauru Basin covers roughly 379,000 square kilometres, almost entirely within Brazil, with a few outcrops reaching into northeastern Paraguay. It is a sub-basin of the much older Paraná Basin, and everything in it was laid down on land. There is no ocean in this record — no ma...

Stratigraphers have argued about how to divide the Bauru Group, and the argument matters more than it sounds. In 1996 Fernandes and Coimbra split it into four formations: Adamantina, Uberaba, Araçatuba and Marília. Two years later Fernandes revised the scheme, breaking the sprawl...

The 1945 discovery happened on Fazenda Cassú, near the old Mangabeira railway station north of Uberaba, in the district of Peirópolis. Price was invited to investigate and worked sites across the region until 1974 — three decades of quarrying in country where fossils tend to appe...

Two groups dominate the Bauru fauna, and only one of them is what most people expect. The sauropods are here in force — titanosaurs, the long-necked giants that were the last great sauropod lineage on Earth. Uberabatitan ribeiroi, estimated at up to 26 metres, is among the larges...

Because the top of the group reaches into the Maastrichtian, the Bauru rocks carry Brazil's record of the final dinosaurs — the ones alive when the asteroid arrived. It is a record with quiet parts. Alongside the titanosaur vertebrae are the shells of snails and freshwater mussel...
