Ray F: As to marine species found high in the mountains. Check out plate tectonics. Take a pencil and figure out what 1/4 inch rise a year can accomplish in a million years.
I come up with 20,000+ feet. So Mount Everest which is still growing could easily have been in the ocean at one time.
Everest actually grows about 3/4" per year, and there's been years it's grown 8 or 9 inches. Regardless your principle is sound.
