Re: Large Dino Growth

[Hilbrecht@xxxxxxxxxxxx (Heinz Hilbrecht)]

Please apologize if I may ask silly questions about dinos - I am only a
poor micropaleontologist. Working offshore from Puerto Rico I liked the
Iguanas there, a smaller version of the Galapagos "dragons". I was told
they have to digest for 12 hours what the eat in an hour (food is mainly
grass). Could this be true for dinosaurs? Maybe it was not the problem to
reach the food but to find a safe place to hang around to digest. Is there
an energy budget for dinos of how much they would have to eat to survive?
How rich were Cretaceous plants? Some of the plant fossils of this time do
not look like easy food.
