Neil H. Shubin, a fourth-year Harvard graduate student in biology, and Paul E. Olsen, a geology professor at Columbia University, had spent a relatively unproductive summer digging at the Nova Scotia site until a misadventure left them trapped by high tide near a cliff on the shore of the Bay of Fundy...
Bourbeau began the Crimson scoring with eight minutes left in the first period when his second shot of the night-a blast from 35 feet off a pass from Randy Taylor on the power-play--eluded Olsen's out-stretched mitt...
...animal families whose fossilized remains are found in the older Triassic rock are missing from the Jurassic layers just above it. The sudden mass extinction opened the evolutionary way for the proliferation of the dinosaurs and the emergence of the mammals. The creatures found in the rock samples, Olsen believes, were among the survivors of that event...
...richest collection of fossil bones of tritheledonts, the group of reptiles most closely related to mammals; a large number of sphenodonts, small, lizard-like reptiles whose only living relative is the tuatara of New Zealand; yard-long crocodiles with spindly legs, a whiplike tail and a sleek body that Olsen calls "the cheetahs of their time"; a trail of penny-size footprints left by a dinosaur no bigger than a sparrow...
...fossil site was apparently in a 300-mile-long rift valley fringed with high mountains. The climate swung between wet and dry spells every 20,000 years or so, leaving telltale alternating layers of lake sediments and sandstone visible on the present-day cliffs. "When it rained," says Olsen, "chunks of rock and mud raced down the mountainsides and buried large swaths of ground." Many of the now fossilized animals escaped the slides, only to be trapped in cracks that opened as the mud flow dried and shrank. Olsen believes the animals entered the fissures in search of water...
