Tooth morphology elucidates shark evolution across the end
WEBAug 10, 2021 · Analysis of the tooth morphology of sharks across the end-Cretaceous mass extinction, 66 million years ago, shows that while generally unaffected, some apex predator shark lineages were selectively impacted; changing habitats and the differential survival of ‘fish-eating’ sharks also reveals responses to ecological cataclysm.
