Sharks and dinosaurs were both prevalent during the same periods, but did they ever encounter each other? Recent evidence suggests that they likely did. Here are the most probable shark encounters with dinosaurs.
Squalicorax, a 16.5-foot-long shark, feasted on a duck-billed dinosaur during the Cretaceous. Remains of the two, documented in the journal Palaios, consisted of a chewed-up hadrosaur foot with a shark tooth embedded in it. Paleontologists are not sure if the shark scavenged on an already-dead dinosaur, which might have keeled over on land before winding up in the water, or if the coastal predator shark killed the dinosaur outright.
