Although some dinosaurs may have spent some time feeding in the water like moose or fishing cats, at most a few became strongly amphibious in the manner of hippos, much less marine as per seals and whales. The only strongly aquatic dinosaurs are some birds. The occasional statement that there were marine dinosaurs is therefore incorrect - these creatures of Mesozoic seas were various forms of reptiles that had evolved over the eons.

The culmination of tyrannosaur evolution, T. rex was one of the very last North American dinosaurs. Nothing else combined its size, speed, and power. Since its demise we have had to make do with lions and tigers and bears, and other "little" mammalian carnivores.

[Velociraptors] are among my very favourite dinosaurs. Their long upcurved skulls, slender yet compact proportions, and great sickle claws make these elegant, attractive, yet demonic animals. There is nothing else like them. Pound for pound, these are among the most powerful of known predators; certainly no other theropod had such a combination of foot, hand, and head weaponry... Among theropods only Tyrannosaurus, with its extreme skull strength, equalled Velociraptor in total power relative to weight.
