The Sobral Formation is a palaeontological formation located in Antarctica. It dates to the Danian stage of the Lower Paleocene period.
Spectacular fossils documenting marine and terrestrial ecosystems soon after the (non-avian) dinosaurs became extinct at the Cretaceous-Paleogene boundary are found in this formation. One of the most significant sites is on Seymour Island.
