Dinosaur urine?

[Roberto Takata <rmtakata@gmail.com>]

Dear People,

I was watching Jurassic Park 3 other day. In a scene, the boy lost in
the Lorna Island show to Dr Grant a flask with T-rex pee.

Well, bird nitrogenous excretion is solid (uric acid) and eliminated
with excrement as the white dielectric material (as described by Arno
and Penzias). How is the N-compounds excretion in crocodiles?

Would a dinosaur produce a watery urine or a pasty one?
