...with political reform. Nigerian citizens cannot afford another military coup, but according to Obasanjo, the real issue is whether the world can afford to pay $30 billion to avoid another military coup in Nigeria. With ambiguities about the future of military institutions in countries such as Nigeria, it would appear that the situation could quickly develop into a blackmail of the global financial assistance system. This is why President Obasanjo's threat to the western world--that if the external debt is not forgiven Nigeria will be forced into a hermit situation to save money--appears...
...lawyer, Mark Holscher, is underwhelmed. "It is unfortunate that unnamed sources appear to be attempting to use the press to revive this flawed investigation," he said. "We continue to believe and expect that Dr. Lee will be exonerated...
...shroud is starting to come off that mystery, thanks to a discovery reported last week in the journal Science. Digging in Madagascar, an international team headed by John Flynn of Chicago's Field Museum has unearthed the fossil jaws of two dinosaurs that appear to be around 230 million years old. "These are either the earliest or among the earliest dinosaurs known," comments University of Pennsylvania paleontologist Neil Shubin. The scientists also found fossils of eight other primitive animals, some of which are a key to the evolution of mammals, which arose at about the same time as the dinosaurs...
...dinosaur bones have not yet been fully analyzed, but they appear to belong to early prosauropods, small herbivores that are most likely the ancestors of the giant Apatosaurus (once known as Brontosaurus). Says Flynn of the little beasts: "I like to think of them being somewhat like kangaroos. They were similar in size, and while they didn't hop, they probably walked about on four legs and stood up on two legs to feed." Most of the other fossils come from rhynchosaurs (parrot-beaked reptiles). The rest are cynodonts, cold-blooded, reptile-like animals--the ancestors of modern mammals...
...dating of this find is indirect. The rocks that held the fossils didn't have the right minerals for radiometric dating. So the researchers relied on known ages of kindred vertebrates (for example, the rhynchosaurs appear to be anatomically primitive cousins of ones known to be about 228 million years old). The scientists pegged the Madagascar fauna at about 2 million years older...
