UAF scientist offers analysis on asteroid and death of dinosaurs
A six-mile-wide asteroid is supposed to have crashed into what is now Mexico's Yucatan Peninsula 65 million years before, triggering a blast that spread death and destruction around the globe.
UAF scientist Michael Whalen is part of a research team that presented a new analysis to support the theory that an asteroid wiped out the Dinosaurs.
Scientists first proposed the asteroid impact theory of dinosaur mass extinction 30 years before. The discovery of a massive crater at Chicxulub [CHICK-shuh-loob], in Mexico's Yucatan Peninsula in 1991, supported that hypothesis.
The Chicxulub crater is more than 120 miles wide - about the distance from Fairbanks to the Arctic Circle - and scientists consider it was created when an asteroid more than six miles wide crashed into Earth 65 million years ago. The cataclysmic impact - a million times more powerful than the biggest nuclear bomb ever tested - triggered massive earthquakes, atmospheric discharge and oceanic upheaval. The ensuing mass Extinction ended both the reign of the dinosaurs and the Cretaceous period, which provide way to the Paleogene period. This theory, having progressively accumulated evidence, was thought to be a near-consensus view.
Some scientists declare that long-term volcanic activity at the Deccan Traps, in what is now India, caused acid rain and global cooling, gradually making life untenable for the dinosaurs and other large animals. They also propose that the Chicxulub impact occurred some 300,000 years before the mass extinctions.

Colorful Dinosaur found out in China
Many scientists have long idea that Dinosaurs were brown or gray in color. But scientists examining the remains of a dinosaur say they have discover evidence it had brightl -colored feathers.
American and Chinese researchers rebuilt the feathers of a flightless dinosaur named Anchiornis huxleyi. The small, two-legged creature lived about one hundred-fifty million year before. It would have weighed only about 110 grams.
The researchers utilized an electron microscope and fossilized remains of thirty feathers that once covered the animal. The remains were found out in Liaoning Province in China.
Researchers learned melanosomes in the feathers. These small, color-producing structures created as the dinosaur was developing. The researchers compared the structures to the melanosomes that manage the color of feathers on modern birds. They were then able to recognize the colors of the Dinosaur feathers.
The researchers state that Anchiornis huxleyi appeared to have a dark gray or black body. They found that the pinnacle of the ancient creature was light brown in color. It had bright white wings. Each of the feathers had black on the last part.

Dinosaur bone watch declared by Louis Moinet
One of the strangest watches in the world is being presented by Louis Moinet, using real Dinosaur Bones in its mechanics.
Most people anticipate to see dinosaur bones in national museums across the globe, yet one pioneering watch firm is allowing history fans to observe them every time they glance at their wrist.
Louis Moinet has announced its Jurassic Tourbillon, which contains fragments of Dinosaur bones in the dial which are dated at 130 million years old and forms part of a new series of novelty timepieces quite exactly named Time Explorator.
The hand-wound mechanical watch also has an impressive 18 carat white gold case and also comes with a bezel and horns that employ no fewer than 56 Wesselton VVS baguette diamonds.
On top of this, the watch also has three dials, while it uses an anti-reflective sapphire crystal front to ensure that reading it is simple in any situation.
Earlier this week, Happy Hour Watches - a wholly cheaper alternative to the dinosaur watch - revealed that its timepieces let buyers to tell the time and, should they want to, open a bottle of beer at the same time with a fancy clasp.

Scientists reaffirm theory that giant asteroid killed dinosaurs
A team of scientists has agreed that a giant asteroid killed off Dinosaurs and a majority of other species on Earth more than 65 million years before.
The researchers examined evidence and agreed it supports a single-impact theory first proposed 30 years ago on the cause of the mass extinction.
Since 1980, scientists have gathered an overwhelming amount of evidence that illustrates a single asteroid about 6 miles in diameter and traveling at thousands of miles an hour, slammed into the Gulf of Mexico, said Richard Norris, a paleoceanographer at the University of California San Diego.
The impact caused a crater 24 miles deep and 125 miles wide, according to Norris, who was part of the research group.
The crater was found out in 1991 in Chicxulub, Mexico, on the Yucatan Peninsula, said scientists who called it the "smoking gun" that backed up the asteroid theory.
Norris compared the asteroid's impact with a blast from hundred million tons of TNT.
"It's mostly more powerful than all the atomic weapons on the planet going off all at once," he said.
The researchers wanted to settle disputes about what destroyed the dinosaurs. Some theories have argued that it would have taken many meteorites to cause such a cataclysmic incident. Another rival theory suggested that the mass Extinction was a consequence of a massive volcanic eruption in India that took place around the same time as the impact.

Dinosaurs might be older than previously thought
The finding of a dinosaur-like animal that lived 10 million years earlier than the oldest known dinos, has suggested that Dinosaurs and other close relatives such as pterosaurs might have also lived much earlier than previously thought.
Asilisaurus kongwe- The new species - shared many characteristics with dinosaurs, but fell just outside of the Dinosaur Family tree.
Asilisaurus kongwe is part of a sister group to dinosaurs identified as silesaurs.
Research into the new species of dinosaurs was carried out by Sterling Nesbitt, a postdoctoral researcher at The University of Texas at Austin's Jackson School of Geosciences.
Even though the oldest dinosaurs found out so far are only 230 million years old, the presence of their closest relatives 10 million years earlier implies that silesaurs and the dinosaur lineage had already diverged from common ancestors by 240 million years ago.
Silesaurs are considered dino-like because they share many dinosaur characteristics, but yet lack key characteristics all dinosaurs share.
The relationship between silesaurs and dinosaurs is analogous to the very close relationship of humans and chimps.
Silesaurs continued to survive side by side with early dinosaurs throughout much of the Triassic Period (between about 250 and 200 million years ago).

Dinosaur's oldest relative discovered
Scientists have discovered a dinosaur-like creature ten million years older than the earliest known Dinosaurs.
Asilisaurus kongwe is a newly discovered herbivore that lived during the middle Triassic period - about 245 million years before.
The scientists say that its age proposes that dinosaurs were also on the Earth earlier than previously thought.
They described their discovering in the journal Nature.
The study was led by Dr Sterling Nesbitt from the University of Texas at Austin in the United States.
He said: "This new evidence implies that (dinosaurs) were really only one of several large and distinct groups of animals that exploded in diversity in the Triassic period, including silesaurs (like this one), pterosaurs, and several groups of crocodilian relatives."
Dr Randall Irmis from the Utah Museum of Natural History in the US was also occupied in the study. He commented that these groups of creatures - the silesaurs - were the "closest relative of the dinosaurs".

Science Uncovers What Dinosaurs Really Looked Like
Scientists have wonderful powers. They can really go back in time and tell you what Dinosaurs look like. They can notify you where plants and babies come from. They’re similar to wizards in labcoats.
The most latest development? Scientists have decoded the complete-body patterns of a dinosaur, so you can see what it really looked like while it was breathing. And boy, does it seem to be kinda weird. Like something you’d fight in opposition to a Soul Caliber game, or a gigantic turkey that frequents dark Hollywood clubs and raves. Basically, totally bizarre.
How did they perform this? How did they dig up the cosmetology secrets of the dinosaurs that are not live and gone? They took pigments from protofeathers and examined them heavily. So the foremost dinosaur we have in complete color is the 155-million-year-old Anchiornis huxleyi. It seems like an irritable chicken-monster that will peck out your eyes in your sleep. It seems like Lady Gaga’s guard dog.
My question is, if science has been capable of colorizing dinosaurs, how long is it until we’ll be able to clone them? I predict at the most, two years, at which point you’ll be able to get teacup dinosaurs as house-pets, and try to make sure they don’t shred your pillows that you bought at Barney’s.

Free of dinosaurs, birds gorged until flightless
SPOILT for food and with their dinosaur predators recently extinct, few birds put on so much weight they became too fat to fly.
DNA examination of giant birds such as emus and ostriches, led by Australian National University's Matthew Phillips, discloses how birds such as the Australasian emu and cassowary, the now-extinct New Zealand moa, the South American rhea and African ostrich scattered around the globe.
The study proposes that flightless birds known as ratites were not necessarily relics of the super continent Gondwana - which drifted apart 100 million years ago to form continents including Africa, Australia and South America - but were able to fly to new lands.
Dr Phillips, an evolutionary biologist, said molecular dating had proposed that the ancestors of these birds became flightless independently about 65 million years ago, around the similar time Dinosaurs became extinct.
Life without dinosaurs not only eliminated a predator, the birds were left with more vegetation to feed on and could spend more time on the ground foraging without worrying about the need to fly from danger.

Yale scientists complete colour palette of a dinosaur for the first time
Deciphering microscopic clues buried within Fossils, scientists have uncovered the vibrant colours that adorned a Feathered Dinosaur extinct for 150 million years, a Yale University-led research team reports online Feb. 4 in the journal Science.
Unlike recently published work from China that inferred the existence of two types of melanin pigments in various species of feathered dinosaurs, the Science study analysed colour-imparting structures called melanosomes from an complete fossil of a single animal, a feat which facilitated researchers to disclose rich colour patterns of the entire animal.
In fact, the analysis of melanosomes conducted by Yale team was so precise that the team was able to allocate colours to individual feathers of Anchiornis huxleyi, a four-winged troodontid dinosaur that lived during the late Jurassic period in China. This Dinosaur sported usually grey body, a reddish-brown, Mohawk-like crest and facial speckles, and white feathers on its wings and legs, with bold black-spangled tips.
'This was no sparrow or crow, but a creature with a very notable plumage,' said Richard O. Prum, chair and the William Robertson Coe Professor of Ornithology, Ecology and Evolutionary Biology at Yale and a co-author of the study. 'This would be a very striking animal if it was alive today.'
The colour patterns of the limbs, which strongly look like those sported by modern day Spangled Hamburg chickens, probably functioned in communication and may have helped the dinosaur to attract mates, suggested Prum.

Dinosaur footprints in quarry to be preserved
Dinosaur Footprints shaped 165 million years ago on an ancient shoreline in north Oxfordshire are to be given special protection by the Government’s conservation experts, Natural England.
The fossilized tracks of dinosaurs together with the Brachiosaurus, a vegetarian, and the carnivorous Tyrannosaurus are in a working quarry at Ardley, near Bicester, close to the M40. It is to be designated a Site of Special Scientific Interest — the first to be sheltered for its geological features alone.
The Fossils originate in the rocks include a variety of sea urchins, clams, molluscs, lamp shells, snails, horseshoe worms, corals and very rare ammonites and nautiloids.
“Geological sites of this quality and significance are few and far between and we are delighted to give this important window on our past the protection that it so clearly deserves.” said Helen Phillips, the chief executive of Natural Englan.
The site is to be protected from exposure to the elements and damage from erosion. Experts will work with the site owners to ensure that the track ways are preserved to permit scientific study.

Jurassic Park to return to the big screen
Dinosaurs are set to wander on the big screen another time with Hollywood bosses planning to bring a second trilogy of the hit sci-fi franchise Jurassic Park.
The original 1993 film that won 3 Oscars, starring Sam Neill and Jeff Goldblum, was a massive victory, grossing USD 914 million worldwide and spawning two sequels, Box Office online reported.
Now, nine years after Jurassic Park III hit cinemas in 2001, Joe Johnston, who directed the third installment, confess a new movie is on the cards which will be closely followed by two more.
‘Jurassic Park IV is going to be presented. And it's going to be distinct anything you've seen. It breaks away from the first three - it's really the beginning of the second Jurassic Park trilogy. It's going to be finished in a completely different way, ‘Johnston said.
If you think of the first three as a trilogy, number four would be the starting of a second trilogy. We just want to make them accepted in their own right. We don't want to create sequel after sequel just because there's a market for it.
We want to tell unusual, interesting stories," he added.

Prehistoric dinosaurs are headed for Coast
There have been millions of dinosaur sightings worldwide in the past 2 1/2 years, and this weekend they’ll be seen wandering through the Mississippi Coast Coliseum in Biloxi.
“Walking With Dinosaurs — The Arena Spectacular” will take viewers back in time. Life-size dinosaurs that breathe ,blink and roar as they fight for dominance will interrelate with each other and the two paleontologists who serve as guides through the 200 million-year History of Dinosaurs on Earth.
Six shows are programmed Friday through Sunday and resident director Lynda Lavin said the educational story line, the stirring music recorded by the Australian Symphony and the sheer Size of the Dinosaurs offer an unforgettable experience for all ages.
“From 3 to 93, we enclose something for you,” she said.
Parents should know if their young children would be scare of the dark arena, the lights and the noises made by the dinosaurs, and prepare accordingly.
“The dinosaurs,do get very close to the audience,” Lavin said.
Lavin describes the 15 huge dinosaurs as life-size puppets that are part Animatronics, part mechanical and completely realistic in their appearance and the way their heads and tails move.
They have to be, she said, because kids might be familiar with their dinosaurs.
“Walking With Dinosaurs” is based on a BBC television series and brings to modern times the dreadful Tyrannosaurus rex, a baby T. rex and the more calm omnivores.

Dinosaurs in your garden with bird-beast revelations at Abergavenny Museum
Combining colourful panels with real and cast Dinosaur teeth ,bones and footprints, this touring exhibition from the geology buffs at National Museum Wales plans to prove the surprisingly close link the unassuming garden bird holds with the decidedly more threatening Tyrannosaurus Rex and Velociraptors.
Scientists are usually in agreement that most of the birds we know and love have evolved from feathered dinosaurs, based on evidence initially surmised through the innovation of a single fossil feather in Southern Germany in 1860.
A year after, the near-complete skeleton of the oldest known bird – dating from 150 million years ago – was found with impressions of feathers conserved in fine mud rock.
They may be widely regarded as friends rather than foes, but today’s birds also bear behavioral traits which are uncannily related to their fiercer ancestors.
Parallel track ways have exposed that dinosaurs moved in herds and packs, nested and built their homes in colonies and, according to fossil sites in Montana and Argentina, built nests and laid eggs.
The meeker breed, though, eventually enjoyed the last laugh. When dinosaurs suddenly became Extinct at the end of the Cretaceous Period 65 million years before, the birds survived.

South Florida Science Museum presents "Diggin' Dinosaurs: An Adventure Millions of Years in the Making"
Something big is coming to the South Florida Science Museum starting January 16th through May 2nd, 2010. Diggin' Dinosaurs: An Adventure Millions of Years in the Making features many of the most feared terrestrial carnivores including the gigantic Giganotosaurus, a genus of carcharodontosaurid Dinosaur that existed 98 to 96 million years ago, to other larger-than-life predators including, the Monolophosaurus, Tuojiangosaurus, Tyrannosaurus rex and Velociraptor. This hands-on exhibit allows visitors to experience dinosaurs by handling an Oviraptor egg, excavating a skeleton, or taking a turn at the Wheel of Dinosaur Misfortune.
The South Florida Science Museum is hosting "Diggin' Dinosaurs" as part of the celebration commemorating the finding of Suzie, the Ice Age mastodon currently on display at the Museum. The skeleton was found in superb condition during an excavation project in West Palm Beach in 1969. Suzie was a juvenile mastodon, a type of pre-historic elephant that wandered Florida and much of North America during Earth's most recent Ice Age.
The South Florida Science Museum has been a resource for scientific information for almost a half century with the mission of exciting curiosity and furthering the understanding of science and technology. Through a strong partnership with the School District of Palm Beach County, the Museum serves as a resource for exploring which compliments and supplements formal educational environments. Diggin' Dinosaurs: An Adventure Millions of Years in the Making is a paleontology based exhibition that is expected to welcome school students, as well as residents and visitors from Palm Beach County and beyond.
"Diggin' Dinosaurs" will be open daily to the public January 16, 2010 to May 2, 2010.

Colorado Museum Makes No Bones about Restoring Dinosaurs to Original Form
Rocky Mountain museum is creating its own Jurassic adventure bone by bone
The mammoth brachiosaurus … the fierce and deadly tyrannosaurus … the fast and nimble velociraptor.
There are more than 1,000 known types of dinosaurs, with an expected 2,000 more yet to be discovered, according to paleontologists - dinosaur experts. We visit the nation's capital to learn more about the huge creatures that populated the earth millions of years ago.
The U.S. state of Colorado is an ideal target for anyone interested in hunting for dinosaur fossils. Like Wyoming, its neighbor to the north, Colorado has its own facility devoted to restoring dinosaurs to their original form, the Rocky Mountain Dinosaur Resource Center.
"What we are trying to do is to present an incomplete specimen in a absolute way. Because if you just have random bones lying around, it's hard for someone to come in and look at it and recognize what the animal looked like in its entirety. And, by filling in the blanks, they see the real material that [has] been used in the reconstruction, but they also see what the animal looks similar in its entirety." Anthony Maltese, curator of the center said.
