because the earth was 1 solid landmass 2/5 the size today no ocean , had much greater oxygen due to increased co2 ,less than 1/2 gravity and would you believe a modern day reptile could get to huge prportion in similar environment afterall reptiles never stop growing.

then i would believe you have a very plausable theory

You guys all so sound so intelligent, but I'll tell you what I once read. There has to have been a change in gravity on the earth from then until now. Less gravitational force would enable something that weighs so much to stand as well as breathe. The largest animals on the planet are no where near the weight of a dinosaur. Yes, I suppose if the conditions were right, they could live on this planet. There is an interesting book called Hunt for the Skinwalker by Kelleher, which postulates the theory that some cryptids are entering earth from other dimensions, and going back. That would account for the fact that bigfoot, etc., are never captured, although seen repeatedly.

This part is totally wrong.
"because the earth was 1 solid landmass 2/5 the size today no ocean "
When dinosaurs were around, oceans had been around for hundreds of millions of years and life had started in the oceans and progressed to the land.

Sounds crazy. So sometime between then and now the Earth suddenly got a lot of mass. Where from? How would large animals survive in the extremely low air pressure of such a low gravity world?
By the way, reptiles stop growing.

Mass can't be killed or created, everything has the same mass since they were first made. reptiles bones stop growing at there time like humans and we can't lose gravity do to the fact that if there was no change in the earth. if there was .5 less gravity on earth trust me you would fell it.

well no because they have different food sources, back then it was a lot of protien and nutrients because they ate each other, but i think it would die because of the pollution and otehr things in the atmospher. that and age'll get them
