He said She said, them big animals back then could get that big due to the high oxigene level in the air amongst a few things. When the oxigene level decreased these larg one simpley was not built for it.

So I've been looking some stuff up and I want to know if my math is right... The average distance between earth and moon is 238,855 miles. The moon moves away from earth at 1.5"/year, that's 12.5 feet every 100 years. 12.5' X? =238,855 238,855/12.5= 19,108.4... Is this correct? If it is, 19,108.4 years ago, the moon would have been scraping the earth...

Why no mention of pliosaurs, plesiosaurs with short necks and big heads like Liopleurodon, Pliosaurus, and Kronosaurus?

It's information like this that makes me believe alternative theories about ancient civilizations. Hearing people speak with such authority on how something behaved so long ago makes you realize it's at best educated guesses presented as fact. Once you realize that everything comes into question
