Book of Jasher 4:18

18
And their judges and rulers went to the daughters of men and took their wives by force from their husbands according to their choice, and the sons of men in those days took from the cattle of the earth, the beasts of the field and the fowls of the air, and taught the mixture of animals of one species with the other, in order therewith to provoke the Lord; and God saw the whole earth and it was corrupt, for all flesh had corrupted its ways upon earth, all men and all animals.



Dinosaurs were created BEFORE the flood by men, using "technology" from fallen angels.

The flood elevated these dead species, hence the finding of FOSSILS in the upper terrains of mountains. Everyone knows dinosaurs have small members (legs and the sorts) so it would take something like the elevation of water to place these dead species in such high areas.

Stop over complicating things.
