Re: Climate Changes Mid-late Dinosaur era.
>>The reason being is that, as I understand it, we notice a significant drop
in the Sauropod and gigantic plant eaters and a larger rise in the lower to
the ground plant eaters, such as Hadrosaurs, Anklyosaurids and others,
whilst the Carnivore side of the spectrum appears to be somewhat similiar
(although there is a shift from the classic Carnosaur to the Tyrannosaur in
the northern hemesphere.)<<
I don't know about that. Titanosaur sauropods were still hearty and hale in
South America and Africa during the Cretaceous. I have the feeling that the
changes in herbivore diversity during the time were due to the rise of
angiosperm plants (didn't HP Bakker say something of the kind).
Anyway, what is "global climate"? You can't say much for Earth's climate, at
the moment, except that temperature tends to hover between the freezing and
boiling points of water.
