The smaller Xiphactinus are three times your length and swallow their prey whole. They’re gill-to-gill with Cretoxyrhina, great white sharks fifty feet long with heads the size of Mini Coopers and twelve-inch nightmare triangles of teeth. Mosasaurs big and small, the runts weighing in at two tons and the alphas like tylosaur a stupefying sixty feet. Under the surface, they’re U-boats with crocodiles’ heads. Pliosaurs in their hunting echelons, competing to see who’s the more viciously ill-tempered. Kronosaurs whose jaws provide the kind of leverage that can snap whales’ spines. Thalassomedons, the biggest of the elasmosaurs, with twenty-foot watersnake necks that allow the Venus-flytrap teeth to be everywhere at once. Dakosaurs gliding through the murk of fish parts spewed by their initial thrashing attacks. And rising out of the blue gloom like the ridged bottom itself easing up to meet you, Lipleurodon, holdover from the Jurassic, the biggest predator that ever lived. Families could live in its skull.
