I read the other day that a Dinosaur with a long neck like a Brontosaurous 
would not have a stong enougth heart to pump the blood to its head, in to 
days strong gravity. It would in fact only last more then a few 
seconds/min according to this article and then die due to lack of blood 
flow. They also said that a very large whale is crushed by its own weight 
if on land today thus proving the theory that the earths gravity is eight 
times stronger today then at that time.  Is this true, sounds very 
diferent to me then what I'm used to hearing.
