When these terrestrial reptiles first appeared 200 million years ago near the end of what geologists call the Triassic Period, tropical or subtropical forests covered much of the landscape. The continents were gathered in a single primordial landmass called Pangaea. Initially, the dinosaurs were relatively small and vulnerable, about the size of ponies. Many of them undoubtedly fell victim to voracious, crocodile-like reptiles called phytosaurs. But by using almost every evolutionary stratagem, they proliferated in number and diversity. Some developed thick protective plating, comparable to that of modern-day armadillos. Ankylosaurus had armor on its skull, knobby stubs over...
...aircraft- a "bogey" in military slang-appears on the radar screen, fighters are scrambled to intercept and obtain a visual would Even if potentially hostile, an intruder would be let alone as long area a remained outside national airspace, which is the area lying above a country's landmass and coastal waters. (It can extend from three to 200 miles out from the coast, depending on the territorial limit a country claims. For the U.S. it is three nautical miles; for the U.S.S.R. twelve.) If that invisible boundary is violated, use law endorsed by both superpowers prohibits...
Still, with a landmass of 8.6 million sq. mi. and a population of 271 million, the Soviet Union would present logistical problems for even the most efficient police organization. The KGB manages to sustain the illusion of being all-powerful largely because Soviet citizens police one another. Schoolchildren are taught to revere Pavlik Morozov, a 13-year-old who was murdered by enraged villagers during the forced collectivization of farms in the early 1930s after he informed local Communist authorities that his father was sheltering more prosperous peasants. Few Soviets today would be likely to follow young Pavlik's example...
...than 1,500 miles along the Transantarctic Mountains. There are strong indications of other treasures as well. More than 200 million years ago, before the world's continents began their slow drift apart, Antarctica was attached to South America, Africa, India and Australia as part of a great landmass that scientists call Pangaea (Greek for whole earth). In strata similar to those of its long-separated continental cousins, Antarctica, like the tip of South America and southeastern Australia, may possess uranium...
