It is doubtful that Tyrannosaurus Rex had lips or that Triceratops had cheeks, says Lawrence Witmer, an assistant professor of anatomy at Ohio University in Athens, Ohio. Witmer was a leading researcher for a study on dinosaur anatomy that was presented at the annual meeting of the Society for Vertebrate Paleontology, which concluded on October 3 in Snowbird, Utah.
Witmer's study reached its conclusions by using high-tech computerized axial to mograply (CT or CAT) scans along with comparative anatomy studies. For example, the theory that Triecratops and similar dinosaur species had cheeks was based on past comparisons with mammals such as sheep. But Witmer's carful analysis found the structure of the triceratops jaw and skull made it more likely that Triceratops had a beak like that of an eagle. Witmer said that scientists should use birds and crocodiles as models when researching the appearance of dinosaurs.
In early October scientists announced that they had confirmed the diseovery of a new type of ceratopsian dinosaur. The dinosaur's hones, found in New Mexico in 1996, are forcing paleontologists to rethink their theories about when ceratopsians migrated to what is now North America.
Scientists previously thought that ceratopsians, the group that included the well-known Tricer amps, arrived in North America from Asia between 70 million and 80 million years ago. During this time, the late Gretaceous Period, the earth's two supercontinents -- Laurasia in the north and Gondwanaland in the south -- were in the process of pulling apart, cutting dinosaur populations off farm each other and interrupting migratory patterns.
The fossilized bones, found by eight-year-old Christopher Wolfe and his father, paleontologist Doug Wolfe of the Mesa Southwest Museum in Arizona, date to about 90 million years ago. This could mean that ceratopsians originated in North America and migrated to Asia rather than the reverse, paleontologists said. Doug Wolfe named the important new species of dinosaur Zuniceratops christopheri after his son.
An expedition from the Universities of Alaska in Anchorage and Fairbanks has discovered a region in remote northern Alaska so rich in fossilized dinosaur tracks that team members dubbed it the "dino expressway". The trampled area was found during the summer of 1998 in Alaska's North Slope near the Brooks Range.
The team found 13 new track sites and made casts from the prints of five different types of dinosaurs. The rock in which the prints were found dates to more than 100 million years ago, or about 25 million years older than the previously discovered signs of dinosaurs in the Arctic region. Paleontologists said that the new findings provide important evidence that dinosaurs migrated between Asia and North America during the early and mid-Cretaceous Period, before Asia split off into its own continent.
Two rich fossil sites in the hills of Bolivia have been recently discovered, exciting paleontologists and dinosaur buffs. This discovery includes one of the most spectacular dinosaur that was ever found.
The discovery of a large site in the mountain region of Kila Kila in southern Bolivia was announced in early October. Here scientists found the tracks of at least two unknown species of dinosaur. These included a large quadruped (four-footed) dinosaur that was probably about 20m (a bout 70ft,) long.
The other site, located not far from the Bolivian city of Sucre, was uncovered in a cement quarry by workers several years ago but was not brought to paleontologists' attention until the mid die of 1998. The site features a v
The passage is intended to tell most clearly about ______.
Nautilus's drilling has only been exploratory most probably because they are not certain about ______.
Many A decade ago, at a time when plaices like Ivory Coast and Equatorial Guinea were being largely ignored by the petroleum world majors in favor of proven mega-sources like Nigeria and Angola--and when their drilling sites could thus be leased for a relative song--Joe Bruso helped put these states back on the map. Bruso was part of a small team working for United Meridian Corp. (later acquired by Ocean Energy) that helped discover and develop the big Zafiro field off Equatorial Guinea. The impact for that country of half a million people, Bruso said in a phone interview from Houston, "has been extraordinary", it was not uninteresting for United Meridian either. Meantime, Ivory Coast, where Bruso and his partner, Coy H. Squyres, discovered the Panthere gas condensate and Lion oil fields, went within a few years from being a net energy importer to a net exporter, and from being an overlooked bit of West African real estate to a place where "you just can't get acreage" for drilling.
Those findings, facilitated by the use of exploration data left behind by the majors, were made on a $1 million annual budget over just four years. The huge returns on a relatively small layout sparked a kind of offshore land rush.
While the impact of such finds has been uneven--some of West Africa's poor say they have seen little of the new wealth oil and gas are expected to flow for years in ways that are making this one of the World's more significant producer regions. Hundreds of sites remain to be explored. "It's amazing the leap to prosperity that the whole place has made," Bruso said of Equatorial Guinea. He is now president of Sovereign Oil Gas, a small Houston-based firm.
American boosters say African oil can help lessen U.S. dependence on Middle Eastern oil. Indeed, a group representing the industry and its backers in Congress and government have called for the Gulf of Guinea to be declared of vital strategic interest. Its waters border Cameroon, Congo, Gabon, Equatorial Guinea and Nigeria. West Africa, led by Nigeria and then Angola and Gabon, now supplies the United States with roughly 15 percent of its oil, but that figure is expected to reach 25 percent over the next decade. West African crude oil tends to be of good quality, selling just below the Brent benchmark. It can reach refineries in the Gulf of Mexico in just 20 days, half the time required from the Middle East, at savings of 35 cents per barrel, according to Petroleum Intelligence Weekly.
Representative William Jefferson, Democrat of Louisiana, has called for a "full-fledged makeover of the U.S. strategic relationship with Africa to take advantage of its petroleum potential. "The United States stands to benefit by having a stable, abundant and relatively inexpensive source of high-quality oil; Africa benefits in that it will receive billions of dollars in badly needed investment and government revenue," he said. "It is a classic win-win situation." West African oil production is now about 3.5 million barrels per day, said Michael Rodgers, senior director of upstream services at PFC Energy in Washington.
West African reserves are forecast to reach 40 billion barrels by 2010, according to Petroleum Intelligence Weekly. All this, Rodgers said, is not going to lead to a new Middle East-size source of oil for the West. His own estimate of total African reserves of 80 billion barrels is a fraction of the 650 billion to 700 billion barrels in the Middle East. Still, he said, it will diminish "the importance of the Middle East".
For Bruso, the development of West African oil is far from complete. A spate of "billion-barrel discoveries" in Nigeria and Angola are yet to be developed, he said, adding that there are seven big sites in development, each likely to produce around 250 million barrels a day. "That's a huge new volume that will be hitting the market starting between 2004 and 2007," h
