...geology's oddest puzzles an odd solution was last week suggested. The puzzle was the origin of "devil's corkscrews," which are fossils six to eight feet high, spiral in shape, with whorls eight inches to three feet in diameter. Buried vertically, they are found in Nebraska's Sioux County in Miocene deposits 15-to 30,000,000 years old. Moreover, fossil beavers have been found in several of the fossil corkscrews, in which microscopic study shows an abundance of petrified plant cells. So two theories arose...
...jobs it offers. An expert Texas micropaleontologist can diagnose the age and character of 100 underground samples a day, making a geological index of 3,000 to 4,000 feet of drilling. In California, where petroleum signs are more complex, scientists must identify about 100 types of fossils in each sample, and analysis is far slower. All told, some 500 fossil experts are hired by Gulf Coast and California oil producers to divine the meaning of the "pebbles" they...
...there evergreens in the South, oaks in the North? Botanist William Spinner Cooper of the University of Minnesota studied fossil tree pollens in peat, concluded that "in America the climate following the glacial epoch was warm and dry, with a return to a cooler moister climate during the last few thousand years." Thus the cone-bearing evergreens of the Southern U.S. are relics of the glacial invasion (which halted at the Ohio River), and the North's oaks and other hardwoods are relics of the warm postglacial period...
