This seems like an odd question at first in these pages, but I suppose we have to be prepared for all types of life we may encounter out there.
The general concensus at the moment seems to be that part of the dinosaur dynasty still lives on in the current bird family.
As birds have no bladder to store urine,
all waste products exit together, as we all know too well:)
My question is, was this trait shared by their distant ancestors the dinosaurs?
Or is this something unique to the bird family?
Over to the ornithologists out there.

It's hard to tell because all we see are bones.


Another question would be. What would life be like if the Asteroid didn't wipe them all out?

Good question. My limited understanding suggests that the quite diminutive mammals in existence 65 million years ago would not have been very competitive with the dinosaurs and reptiles without such a planet-wide niche-cleaning. And whether or not the reptiles could have developed speech and subsequent language necessary for intelligence and culture is also a question for consideration.

One might also wonder if the evolution of a global population of intelligent reptiles might have altered the outcome of the recent presidential elections in the United States. Or, given such reptilian preeminence, might the results seen here in November have been even MORE likely?

Of course, but when the T-Rex's got together massive erosion happened, ergo we now have the grand canyon ... seriously though, I've heard recordings of sounds that some scientist think the dinosaurs made, synthesised or course, but I wonder if they have any evidence of urinary tract or bladder.
On another note, I've read a really good book called "The Great Guano Rush" by Jimmy M. Skaggs that explains whey the United States has so many south sea islands in there possesion. Basicly it has to do with massive mounds of bird droppings that were used for fertilizer.

Dinos' demise debate rages on

Sue, the largest and most complete T. rex ever found, at the Field Museum in Chicago. Paleontologists have reopened the debate concerning the disappearance of T. rex and the other dinosaurs at the end of the Cretaceous.

I echo that sentiment.
Welcome back, SIR Richard!

Now, did those Dinos pee or what?
