Not so much. All of the water that has ever been on earth has been recycled through evaporation then rain or snow and so on since the earth began. So dinosaurs drank water and peed and the water was absorbed into the ground which filtered it and then it rose to the surface, evaporated, rained and so on. So yes it is the same water the dinosaurs used but any trace of dinosaur pee has long ago been filtered out.
There is a very, very, very, very small amount of new, un-recycled water coming out of the mantle, but the water we drink is the same water that the dinosaurs drank first!
Water is continuously replenished. Same water exists as it did earlier.
No dinosaurs specifically lived in the water. Plesiosaurs, pliosaurs, mosasaurs and ichthyosaurs lived in the water (but are not DINOSAURS). They are reptiles but not dinosaurs. They co-inhabited the planet with dinosaurs, in the same way that the pterosaurs ruled the air. Pterosaurs were not dinosaurs either.
According to most scientists, we have had virtually the same amount of water on Earth since the planet formed. That would mean that there was the same amount of water on Earth when the dinosaurs existed. However, it is important to note that there is probably an infinitesimal amount more water now then there was in the time of the dinosaurs, simply because of the fact that there have been meteors/meteorites that carried a little bit of water to Earth since the dinosaurs died out.
the same amount of water we have today... (70%)
They drink the same thing you do
Pigs drink water in the same way that dogs do. Pigs will lap up the water they need with their tongues.
the water the earth was formed with
They drink water because if they didn't they would die, and if is a way of keeping their body working in the heat of the African day.
When lobsters drink, they drink water. They do not metabolize salt in the same way that most animals do. They suffer no ill effects of salt water.
