On the contrary, done all the time by Mother Nature. It's a good bet that a good fraction of glass of water you drink passed through a dinosaur at some time :-)
PS: For the mathematically inclined, there are about 3.26e20 gallons of water on Earth. Figure about a billion dinosaurs alive at any moment, each drinking 1 gallon of water a day. That's 3.65e11 gallons per year. Dinosaurs existed for about 100 million years, so cumulatively drank and excreted 3.65e19 gallons of water, so by simple math 11% of all water was once dinosaur piss.
Now we've got about 65 million years of mammals to think about...
