...back alive, so to speak." The experiment's success goads Hammond to exploit the made-from-concentrate behemoths for profit. He hatches the dinosaurs on a Central American island and builds a theme park around them. Before the scheduled opening, a few guests -- including craggy paleontologist Alan Grant, lissome paleobotanist Ellie Sattler and Hammond's two young grandchildren -- come to Jurassic Park for a sneak preview. Then things go spectacularly wrong. The novel's first half is a controlled tram trip through this high-tech zoo, the second half a terror- filled obstacle course strewn with dinosaurs amuck: swooping pterodactyls...
...matted leaves lying half buried on the rock-strewn hillside make it clear that a thick forest once stood there, trees that grew 150 ft. high and lived 1,000 years. "You can read the rings -- they look modern, like a lush forest area logged fairly recently," says Paleobotanist James Basinger of the University of Saskatchewan. "But then ) you look around, and you're in a desert. The only trees are dwarf willows one and two inches high." The sparse growth surrounding the half square mile of fallen trees is not surprising: the location is Axel Heiberg Island, less than...
When did life begin on earth? Harvard Paleobotanist Elso S. Barghoorn and his onetime student, J. William Schopf, discovered a possible answer to that intriguing question several years ago, when they found microscopic fossils in ancient South African rocks. These tiny traces of life indicated that single-celled creatures existed as long as 3.1 billion years ago. Now a team headed by Schopf himself has found evidence that could push the dawn of life back at least another 200 million years...
...countryside of desert valleys in central Utah that 150 million years ago was a lush tropical shore along an inland sea, inhabited by huge flesh-eating dinosaurs. The area has thus yielded a rich supply of plant and animal fossils. Examining a specimen of the fossil under a microscope, Paleobotanist William D. Tidwell of Brigham Young University recognized the unmistakable cellular structure of the palm...
Swedish Explorer Johan Gunnar Andersson discovered several of its fossilized branches on Norway's Bear Island in 1899. Remnants of its fanlike leaves have since been found in Alaska. But it remained for Bonn University Paleobotanist Hans-Joachim Schweitzer to determine that an ancient plant called Pseudobornia ursina was actually a tree that grew as high as 65 ft.-50 million years earlier than other trees of comparable height are known to have appeared. On a recent expedition to Bear Island, Schweitzer reports in the current issue of the German journal Umschau, he unearthed the first portion of Pseudobornia...
