any evidence that T-rex may have hopped like a kangaroo?
Watching the nature channel I couldn't help notice the similarity between the body of a t-rex and a kangaroo. I suppose the bone structure of a hopping dinosaur would be obvious to a paleontologi...

Egg or not ?
It sure does look like an egg. It has evidence of shell, the inner membrane of the shell and a smooth albumen look to the body. I wish I could see if the mark on the non-pointy side has evidence of ...

Isn't the evidence pretty strong that Neanderthals were primarily carnivorous while Cro-Magnons were more balanced omnivores?
T-Rex; Predator or Scavenger
I've seen that scenario based on fossil evidence examined by paleontologists on Jurassic Fight Club. That's certainly pluasible, though.
Extinction of Mega Fauna 13,000 years ago
Kenobi, about the air burst I have heard as well. Not much 'evidence' to it though - but certainly another option that has to be taken into consideration of the chances for the extinction.
