Lets say Jurassic park somehow came to existence and someone cloned dinosaurs genetically identical to ones of the past and tried to keep them in a zoo. Could the dinosaurs survive as is?

I'm specifically wondering if, given the change in atmosphere and environment over such a large time period, non-avian dinosaurs could survive in a modern world who's environment is so different from what they were evolved for? For now ignore the issue with finding prey and a successful evolutionary niche, their being fed by some zoo staff or something.

    $\begingroup$ "Dinosaurs" is a very large group. It's like asking if "mammals" could have survived in an earlier time period. $\endgroup$

    $\begingroup$ Which kind of hard-science do you expect here? I am not aware of anybody who has written papers on the integration of non avian dinosaurs into present biomes. $\endgroup$
