    Xiphactinus was a primitive teleost that swam in Late Cretaceous seas where North and South America, Europe, and Australia now stand. At up to 5.1 m in length it was as large as today’s largest bony fish. Swinging its short “bulldog” jaws open wide to reveal its prominent conical teeth, it could seize and then swallow a fish as long as a human. This is known because the guts of one fossil Xiphactinus contain the remains of Gillicus, another neopterygian, which was 1.8 m long. It is thought that some Xiphactinus died because they tried to swallow prey that was too big.
