Abstract in brief

A new giant freshwater turtle from the Late Pleistocene of the Brazilian Amazon has been discovered, challenging the idea that only megamammals drove Pleistocene extinctions, and highlights the diversity of large reptiles during that period.
The turtle, based on a massive lower jaw, is closely related to modern Amazonian species, likely had an omnivorous diet, and could have reached up to 180 cm in carapace length, making it one of the largest freshwater turtles ever discovered.
This finding provides the latest evidence of giant freshwater turtles coexisting with early humans in the Amazon, suggesting their potential role in Pleistocene ecosystems alongside human activity.]
