There are a lot of clearly theropodian footprints, and as far as I know none of them show evidence of hopping, but then again, we would not expect to see such evidence unless *most* ...
That is a non-sequitor because the proponents of the bird-theropod hypothesis suggest that birds are not just dinosaurs, they are descendants of a specific kind of theropod, i.e. they are more closely...
Well, you are right by saying that we have very limited fossil evidence of spinosaurids because the only 'well preserved' Spinosauridae are Baryonyx, Suchomimus, Irritator (of which we only have a sku...

Evidence does not have to be published to be evidence. A fossil is not a rumor.

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 ...

More than you think. Besides, does it mean that you only appeal to authority, instead of evidence?
You are correct. I misread you. It is more properly labeled a quasi-pygostyle.
Presumably the...

I've seen that scenario based on fossil evidence examined by paleontologists on Jurassic Fight Club. That's certainly pluasible, though.

Nah. I think that there is much more evidence for other things.
Those would have to be some evil bugs, too.
Hi all,
Does any one any decent evidence to prove whether herbiverous dinos were warm or cold blooded or were they homeothermic?

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.
