Plesiosaur feeding
Plesiosaur feeding encompasses the ways these marine reptiles captured and consumed prey, shaped by their jaws, teeth, necks, and swimming bodies.
Plesiosaur dentition: The arrangement and form of teeth in plesiosaurs, varying from fine, interlocking needles to stout, crushing crowns. Tooth form suggests whether a plesiosaur trapped slippery prey or processed harder food.
Cryptoclidus: A Middle Jurassic plesiosaur genus with numerous slender teeth and a relatively small skull. Its fine teeth are consistent with capturing small, soft-bodied prey.
Plesiosauria: An extinct order of marine reptiles that lived from the Late Triassic to the end of the Cretaceous. Plesiosaur feeding strategies varied across the group's many body forms and lineages.
Plesiosaur gastroliths: Stones found in some plesiosaur fossil skeletons, whose functions remain uncertain. Their presence has prompted dietary explanations, but they do not establish a specific feeding method.
Plesiosaur skull: The skull anatomy of plesiosaurs, including jaws, teeth, and openings associated with sensory and respiratory structures. Jaw mechanics and tooth placement set the limits on prey capture and handling.
Rhomaleosaurus: A genus of large-bodied, short-necked plesiosaurs from the Jurassic Period. Its robust skull and teeth suggest a different prey-capture strategy from long-necked forms.
Plesiosaur fossils: Fossilized remains of plesiosaurs, including bones, teeth, and occasional preserved soft tissues or gut contents. Feeding behavior is inferred from fossil anatomy and rare traces of actual meals.
Plesiosaur paleobiology: The study of plesiosaur biology, ecology, and behavior from fossil evidence. Feeding reconstructions depend on broader interpretations of plesiosaur anatomy and ecology.
Plesiosaur neck: The elongated or compact cervical region connecting a plesiosaur's skull to its trunk. Neck length and flexibility may have affected how prey could be approached and seized.
Pliosaurus: A genus of large, short-necked plesiosaurs with powerful jaws and large teeth. Its build illustrates how some plesiosaurs were adapted to seize substantial vertebrate prey.
