What is this silliness?
That's true, I have been operating under that stupid, evil assumption.
So here's my breakthrough in understanding
a) all creatures with the breath of life perished in the flood
b) some dinosaurs escaped the flood waters and survived into the modern age
new scientific fact: dinosaurs were water breathers... like fish
It's all so obvious and logical
(b) Some dinosaurs survived on the ark, but didn't do well in the new climate after the Flood, although as someone pointed out some of them survived long enough to give rise to all the dragon stories. None of them "survived into the modern age."
Water breathers? What?
