So it’s probably not been in Hitlers mouth. Dinosaur piss I’ll leave as an exercise for the reader.

I’m on it. Dinosaurs lived for millions of years, so if we assume at least one dinosaur per year, there were likely at least a million dinosaurs. Dinosaurs are also very big. This means they probably stored a lot of pee. How much pee? Based on their size, probably at least a gallon or more. So now you’ve got 1 million gallons of dinosaur pee. With 8.025 billion people on Earth, that’s roughly 1/2 teaspoon of dinosaur pee for every living human!
