HOw could something that large subsist as a herbivore?
It would have to consume tons of fodder a day?
Would the enviroment of that time have supported them?
Are we sure cave men weren’t putting steroids in their feed?
I think I saw that on the Flintstones.
For you believers out there, the pre-flood vapor canopy theory explains this nicely. With 2X the oxygen density in the atmosphere, little fluctuation in daytime and night temperatures, plus abundant moisture, plants and things would grow VERY large. Further, if you believe that before the Fall, there was no sin and thus no death in the world, animals without a growth inhibiting factor (like fish and reptiles)would continue growing as long as they were alive. There are even skeletal examples of very large people who lived in pre-historic times. Or not, if you prefer.
Global Warming helped grow huge plants until the big dinosaurs, the SUV's of the era, emitted enough methane to ignite the flora and fauna, thus hastening their demise.............
You must be Clueless. Ask that noted Vegan, Alicia Silverstone
Imagine a nest of these hatching and the mother dino faced with a dozen beaks open at once: “Feed me! Now!”
