Jurassic sea ambush: a pliosaurid tooth pierced an ichthyosaur’s spine
A rare fossil shows a pliosaurid tooth embedded in an ichthyosaur vertebra, providing direct evidence of a predation event in the Upper Jurassic. CT imaging confirms the tooth’s origin and suggests it was ripped from the predator during a fatal bite, with provenance traced through Victorian-era museum records, illustrating how old collections can reveal dramatic moments from ancient oceans.
