I am trying to develope some ideas on the extinction of the large dynosaurs.
As I am new to this list I do not know if these questions are simple
or they have already been discussed> In that case I apologize in advance.
However the idea has partly to do with my thesis so I would appreciate any
The basic idea is that a catastrofic event (like a meterite impact)
could have caused global changes in temperature of the earth affecting
the vegetation. Assumimg the large dinosaurs to be cold blooded and
grass-eaters, such a change in vegetation coiuld have ended with the
large dinosaurs, because they would not have had enough food to maintain
My concrete questions are:
1) are there still any cold-blooded grasseating reptiles?
2) how much food, in relation to its size, would a cold-cblooded
reptile need to maintain itself (e.g. a dinosaur of 2000 kg)?
Thanks for any help
