Fossilized sea life lies atop every major mountain range on Earth—far above sea level and usually far from the nearest body of water. Attempts to explain “seashells on mountaintops” have generated controversy for centuries.a
An early explanation was that a global flood covered these mountains, allowing clams and other sea life to “crawl” far and high. However, as Leonardo da Vinci wrote,b under the best conditions, clams move too slowly to reach such heights, even if the flood lasted centuries. Also, Earth does not have enough water to cover these mountains, so others said that some sea bottoms sank, leaving adjacent seafloors (loaded with sea creatures) relatively high—what we today call mountains. How such large subterranean voids formed to allow this sinking was never explained. Still others proposed that sea bottoms rose to become mountains. The mechanisms, forces, and energy required to push up mountains were also never explained. Because elevations on Earth change slowly, some wondered if sea bottoms could rise miles into the air, perhaps over millions of years. However, mountaintops, which experience destructive freezing and thawing cycles, erode relatively rapidly—and so should fossils slowly lifted by them. Also, mountaintops accumulate few sediments that might blanket and protect such fossils. Some early authorities, in frustration, said the animals and shells grew inside rocksc—or the rocks simply look like clams, corals, fish, and ammonites. Others denied the evidence even existed. Today, geologists rarely acknowledge all the seashells on mountaintops.d
The means by which mountains were pushed up in hours during a global flood will soon be presented. The mechanism is simple, the energy and forces are sufficient, and supporting evidence (pages 108–414) is voluminous—not just seashells on mountaintops.
