A new notosuchian crocodyliform from the Early Palaeocene of Patagonia and the survival of a large-bodied terrestrial lineage across the K–Pg mass extinction | Proceedings of the Royal Society B: Biological Sciences Sebecid notosuchians are the only terrestrial crocodyliforms to survive the Cretaceous–Palaeogene extinction, 66 Ma, which eliminated large-bodied species (above approximately 5 kg) in terrestrial ecosystems. Early sebecid evolution is unclear due to the ...
