Due to water cycle of Earth, is it possible that ...?

the water you drink used to come from dinosaur’s urine millions of years ago?

    Absolutely possible. Water is recycled over and over again and again. Water is a catalyst that can change the structure of other chemicals and yet can be filtered out to be pure again.

    The chance of you drinking even a single water molecule that passed through the body of a dinosaur is less than 1 in a godzillion.

    The whole earth is a filter system 

    The chemical makeup of urine is 90 percent water 

    Plants absorb water that has fish whale and other contaminants in it and filters the water

    There is a man made a trough around his house with plants in water from his toilet went in one side clean drinkable water came out the other so the answer would be no not from dinosaurs

    not in bulk, not as a single packet, no.  but a good portion of all water has been through another life form in the past.  Not like new atoms are being created.  they all get used and reused, again and again (with very minor exceptions).

    You can't unmix the pee once it ends up mixed in with other water.

    Yes, quite possible.

    Yes...and people's urine a year ago (or less).

    yes, but only a few molecules of it.

    Yes. It's even possible to roughly estimate the amount of water from the dinosaur’s urine in a glass of drinking water. Actually I answered a similar question about a decade ago but it was about the air, not water. Funny thing that I remember.


    This could be a tricky question because we don't know exactly whether dinosaurs peed or not. Their living relatives, birds and crocodilians, have a cloaca - a single opening in their rear for both liquid and solid waste. Most birds (yes, pidgeons too) combine pee and poop into a single stream. On the other hand (I find "on the other hand" funny in this context), ostriches and crocodylians expel liquid and feces through cloaca in sequence, not at the same time. Did dynos pee, nobody knows yet.
