Geologic map of Seymour Island, Antarctica with the Sobral Formation in brown
The Sobral Formation is a palaeontological formation located in Antarctica. It dates to the Danian stage of the Lower Paleocene period.[1]
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.[2] One of the most significant sites is on Seymour Island.
