The last 10 or so feet of a Diplodocid's tail is constructed in the same way a certain weapon of the marshal arts fighters is built, but instead of the bones being held together by a chain link, the tail vertebrae were held together by tough, tensile, elastic organic material. I remember, playing with a piece of long thick rope making supersonic whip-cracking sounds, when I was a kid. But the idea itself should not be rejected easily. Though, we can hardly except these facts - some bacteria live in a boiling water, some other organisms in ice, some in acid. We could find countless examples like this.
Mother nature is still smarter than science.
Imagine, that the elephants were extinct long before humans and that paleontologists discover a mummy with a well preserved trunk. First, we'd all be amazed, then intrigued with a purpose of such an organ. And I bet you, many conservative scientists would conclude the bizarre trunk was to weak or fragile for any other purpose than decorative, and that it hung from the animal's head lifelessly dragging on the ground. Obviously, the promoters of the idea were never being chased by an angry ram or goat. Recent research in African national park, where the program of sawing of horns of live rhinos, to prevent poaching, resulted in increased loss of rhino offspring, due to the more efficient predation.
