Of course. You've heard of the coelacanth, supposedly extinct 25 million years before the dinosaurs died off but still around today. That's famous because we thought it was extinct, but there are all kinds of fish, shellfish, mollusks and such that never get applause for surviving because they're always been recognized as extant (still living). How about the sharks? They were present in Mesozoic seas.
Dinosaurs never lived underwater. There were marine reptiles that are sometimes inaccurately called dinosaurs; these include icthyosaurs, mosasaurs, plesiosaurs, and pliosaurs. All of these are extinct. There are a few marine reptiles alive today, though. These are sea turtles, sea snakes, and the semi-aquatic marine iguana.
Dinosaurs were all reptiles and therefore, land dwellers. None of them could breathe underwater, although marine creatures that lived along side the dinosaurs have similarities to the dinosaurs, they weren't actually classed as dinosaurs. Therefore, no dinosaurs could breathe under the water :) EDIT Fish and some amphibians are the only vertebrates that have gills and can breath underwater. The same applies to ancient animals too.

Gills, as opposed to lungs, can filter out oxygen from water. And oxygen is something most creatures need to stay alive.
