Even some public school textbooks sort of acknowledge the difference between historical and observational science.

Since none of the creatures of the sea were taken on Noah's ark, there would be a strong possibility that some plesiosaurs and maybe even some ichthyosaurs survived the Flood. The violent and turbulent waters of the Flood would surely have killed and buried many of the sea creatures (over 90 percent of fossils found are of marine animals). However, if some had survived the Flood and lived on in the seas for years after, they could help account for many of the legends of sea monsters that have been gathered from all over the world. Remote as it may seem, there could even be the possibility that a few have survived till modern times. After all, it's much easier to believe that they could have survived for several thousand years rather than for nearly a hundred-million years.
