“It might possibly have been a factor in the Flood.”
Have heard the theory that the dinosaurs disappeared immediately after the flood. The atmosphere had changed so much that their small nasal and respiratory system could not sustain them.

Problem is that the dinos have not yet disappeared; they just are not as big anymore because we have about 1/2 as much atmospheric oxygen, and they don’t live long enough to get big.
I am anything but dogmatic, but I think they disappeared DURING the Flood. They didn’t get on the ark. My opinion is, these fierce ones, were the result of deliberate genetic manipulation.
