Research unearths new dinosaur species

Friday, March 1, 2013

A South Dakota School of Mines & Technology assistant professor and his team have discovered a new species of herbivorous dinosaur and published the first fossil evidence of prehistoric crocodyliforms feeding on small dinosaurs.

Research by Clint Boyd, Ph.D., provides the first definitive evidence that plant-eating baby ornithopod dinosaurs were a food of choice for the crocodyliform, a now extinct relative of the crocodile family. While conducting their research, the team also discovered that this dinosaur prey was a previously unrecognized small ornithopod dinosaur species, which has yet to be named.

The evidence found in what is now known as the Grand Staircase Escalante-National Monument in southern Utah dates back to the late Cretaceous period, toward the end of the age of dinosaurs, and was published Feb. 27 in the academic journal PLOS ONE (Public Library of Science ONE).

A large number of mostly tiny bits of dinosaur bones were recovered in groups at four locations within the Utah park ? which paleontologists and geologists know as the Upper Cretaceous (Campanian) Kaiparowits Formation ? leading paleontologists to believe that crocodyliforms had fed on baby dinosaurs 1-2 meters in total length.

Evidence shows bite marks on bone joints, as well as breakthrough proof of a crocodyliform tooth still embedded in a dinosaur femur.

The findings are significant because historically dinosaurs have been depicted as the dominant species. "The traditional ideas you see in popular literature are that when little baby dinosaurs are either coming out of a nesting grounds or out somewhere on their own, they are normally having to worry about the theropod dinosaurs, the things like raptors or, on bigger scales, the T. rex. So this kind of adds a new dimension," Boyd said. "You had your dominant riverine carnivores, the crocodyliforms, attacking these herbivores as well, so they kind of had it coming from all sides."

Based on teeth marks left on bones and the large amounts of fragments left behind, it is believed the crocodyliforms were also diminutive in size, perhaps no more than 2 meters long. A larger species of crocodyliform would have been more likely to gulp down its prey without leaving behind traces of "busted up" bone fragments.

Until now, paleontologists had direct evidence only of "very large crocodyliforms" interacting with "very large dinosaurs."

"It's not often that you get events from the fossil record that are action-related," Boyd explained. "While you generally assume there was probably a lot more interaction going on, we didn't have any of that preserved in the fossil record yet. This is the first time that we have definitive evidence that you had this kind of partitioning, of your smaller crocodyliforms attacking the smaller herbivorous dinosaurs," he said, adding that this is only the second published instance of a crocodyliform tooth embedded in any prey animal in the fossil record.

"A lot of times you find material in close association or you can find some feeding marks or traces on the outside of the bone and you can hypothesize that maybe it was a certain animal doing this, but this was only the second time we have really good definitive evidence of a crocodyliform feeding on a prey animal and in this case an ornithischian dinosaur," Boyd said.

The high concentrations of tiny dinosaur bones led researchers to conclude a type of selection occurred, that crocodyliforms were preferentially feeding on these miniature dinosaurs. "Maybe it was closer to a nesting ground where baby dinosaurs would have been more abundant, and so the smaller crocodyliforms were hanging out there getting a lunch," Boyd added.

"When we started looking at all the other bones, we starting finding marks that are known to be diagnostic for crocodyliform feeding traces, so all that evidence coming together suddenly started to make sense as to why we were not finding good complete specimens of these little ornithischian dinosaurs," Boyd explained. "Most of the bites marks are concentrated around the joints, which is where the crocodyliform would tend to bite, and then, when they do their pulling or the death roll that they tend to do, the ends of the bones tend to snap off more often than not in those actions. That's why we were finding these fragmentary bones."

Harlem Shake protesters push for change in Egypt

Youth activists gathered in front of the Muslim Brotherhood's headquarters in Cairo to dance the Harlem Shake in protest of Egypt's ruling party. NBCNews.com's Dara Brown reports.

By Charlene Gubash, Producer, NBC News

CAIRO -- It is the latest Internet phenomenon that has the world laughing, but in Egypt the Harlem Shake has caught the imagination of revolutionaries who are using it as a new way to challenge the country's new Islamist rulers.

"It?s a funny way to protest how [the Muslim Brotherhood] have taken control of the country,? said law student Tarek Badr, 22, who was one of more than 100 thrusting their hips in front of the political movement?s Cairo headquarters on Thursday. "People won?t be silent. They will protest in all ways and this is a peaceful way."

One of his fellow white-clad protesters wore a Mickey Mouse head mask.

The unusual protest captured the attention of Egypt?s protest-weary press corps -- who almost outnumbered the gyrating protesters -? as well as a dozen stern-faced members of the Muslim Brotherhood. The movement's figurehead Mohammed Morsi was named president in June after the country's first democratic election in decades.

Organizer Noor al Mahalaawi, a 22-year-old engineering student, and three friends started a group that they have dubbed the "Satiric Revolutionary Struggle".

A protester wearing a Mickey Mouse mask dances the Harlem Shake in Cairo on Thursday.

The group intends to stage innovative weekly protests in front of the party headquarters, which will be posted on its increasingly popular Facebook page.

"People are very supportive,? Mahalaawi said. ?It?s a change from violence to sarcasm and it?s peaceful. There has been enough blood, enough arrests, enough trials.?

He said the message to the party was that many Egyptians ?do not like their way of rule? with human-rights violations every day."

After their Harlem Shake ended, participants took up the new revolutionary chant: ?"The people want the fall of the ?Murshid? [the supreme guide of the Muslim Brotherhood]."

An impromptu conga line snaked through crowd shouting, "Leave, leave, leave.?

One onlooker, wearing red velvet devil horns, cheered them on. "The Muslim Brotherhood are the friends of the devil," explained Iman Abdul Munim, a women?s rights activist.

A handful of the Muslim Brotherhood's supporters somberly kept guard. They ushered journalists and onlookers off the thin strip of grass in front of the gated building.

"It?s not allowed to stand here," said Wala?a Mohamed Omar, a 35-year-old telecom employee, who heard about the event and came to protect party headquarters. "I have not been paid to do this, I came for the sake of God."

Move over, PSY and Carly Rae Jepsen: There's a new video craze that has exploded online. The Harlem Shake involves massive dance parties breaking out to a catchy beat seemingly out of nowhere. TODAY's Matt Lauer reports, and the TODAY anchors and staff show off their Shake skills.

He was visibly unamused by the Harlem Shake antics, but conceded: ?Everybody is free to express themselves as they wish. We are all Egyptians and don?t differ. We respect our opinion and theirs. That is what the two-year revolution was all about.?

But in Egypt, the rise of Islamists to power has changed the fabric of society, now sharply split between fundamentalists, who favor the implementation of Islamic law, and moderates who want secular government.

Many young Egyptians feel their freedom is under siege and the Harlem Shake protest is one small way to reclaim it. "It is all about freedom of expression," insisted Mohamed Mostafa, a 19-year-old law student. "We are free people and we will do what we want."

Despite the end of the military state, Egypt?s police were accused in January of a?return to Mubarak-era abuses after a video showed riot police?stripping and beating a middle-aged man.

And a series of missteps by Morsi -- including a bid to grab sweeping powers even before the dust had settled on the country?s constitution ??has brought protesters back onto the streets.

On Tuesday, a coalition of leftist and liberal parties known as the National Salvation Front announced it would boycott upcoming parliamentary elections, claiming Morsi is driving through an Islamist agenda and breaking a promise to govern on behalf of all Egyptians.

Students from Tunis Carthage Private University dance the Harlem Shake on Wednesday in Tunisia.

The Harlem Shake protest idea has also taken on elsewhere. In Tunisia, the Harlem Shake dance became a rallying cry for high school and university students after the Minister of Education Abdellatif Abid threatened? to expel Tunisian high school students at a high school where it was performed and to sack complicit staff.

Tunisian Salafists - Islamic extremists - clashed with students on Wednesday as they tried to film the dance at a university.

Insight: Will Dreamliner drama affect industry self-inspection?

SAN FRANCISCO/SEATTLE/PARIS (Reuters)- Eight years ago, U.S. regulators substantially increased their dependence on the aircraft industry to help keep flying safe.

The U.S. Federal Aviation Administration (FAA) said it would no longer directly manage routine inspection of design and manufacturing. Instead, it would focus on overseeing a self-policing program executed by the manufacturers themselves through more than 3,000 of their employees assigned to review safety on behalf of the FAA.

These so-called designees had existed for decades, but the FAA had vetted and controlled them. Under the new system, companies chose and managed them, to the point where the FAA even had trouble rejecting those they felt were unsuitable for the job, according to one government watchdog.

As the drama of the overheating lithium-ion batteries on the Boeing 787 Dreamliner unfolds, that relationship is coming under intense scrutiny.

No evidence has surfaced that the designee system is responsible for the battery problem that has prompted regulators to temporarily ban the plane from the skies. The story has raised the question, however, whether the regulator hands over too much power to the industry.

"This is an occupation with a built-in conflict of interest," said Gordon Mandell, a retired FAA certification engineer.

With Boeing doing about 95 percent of its own inspections, adds Mary Schiavo, former Department of Transportation inspector general, "it's kind of do-it-yourself." The situation was not unique to Boeing, she said. "There are places around the world that saw an FAA inspector once, maybe five years ago, and that's it."

HOW WERE TESTS VERIFIED?

Boeing's new ultra-modern carbon-composite jet has been grounded around the world for six weeks as the National Transportation Safety Board leads an investigation into two battery incidents, joined by the FAA. Both agencies are also looking into the 787 certification process.

"We need to understand what tests were done and who was certifying those tests, and again how they were verified - not just by Boeing, but by the regulator as well," NTSB Chairman Deborah Hersman said on February 8, referring to the battery and other key parts made in a long, global supply chain.

At the broadest level, even some supporters of the designee process are asking whether the FAA is up to the task of effectively overseeing the system.

Among them is Ken Mead, another former DOT inspector general and a veteran of investigating the FAA. "The questions I'd want answers to are: Does the FAA have the right people with the right expertise to make sure the FAA is in a position to critically second-guess? And have they critically reviewed the approval process so this does not happen again?" he said.

The FAA's defense of its abilities and approach is unwavering. "Some have asked the question whether the FAA has the expertise needed to oversee the Dreamliner's cutting edge technology. The answer is yes, we have the ability to establish rigorous safety standards and to make sure that aircraft meet them," FAA Administrator Michael Huerta said in an industry speech on January 23. "The way to enhance safety is to keep the lines of communication open between business and government."

The FAA and Boeing both say the FAA is better off managing the system and picking out high-risk areas on which to concentrate. It lacks the resources to manage every individual and inspect every part, they say, and industry has a strong incentive to cooperate - unsafe products jeopardize business. They point out that FAA staff invested more than 200,000 hours over eight years certifying the 787 on top of work done by designees.

Perhaps their biggest defense is that there have been no fatal crashes of scheduled commercial flights in the United States for four years.

BIG JOB, NOT-SO-BIG BUDGET

The FAA's inability to expand its budget in line with an increasingly large, complex and global aviation industry played a major role in the 2005 decision to expand the delegation system. Certification work increased fivefold between the 1940s and 1990s and has only become more complex since.

"By shifting our inspection focus from reviewing test results to overseeing the designation program, we will be able to more efficiently use our resources while extending our oversight coverage, thereby increasing safety," the FAA said in the official announcement of the program, printed in the Federal Register on October 13, 2005.

It added, however, that "More than one commenter states that the FAA should be hiring more inspectors, not spending its limited resources creating an organizational designee system." Public comments from opponents of the new system outnumbered supporters 14 to 11, it noted.

While the agency still signs off on a new plane and key steps along the way, the bulk of the interim work - often 90 percent or more - is done by the designees at the manufacturers. As of 2010 there were about 1,000 FAA engineers and inspectors devoted to design review and inspection, compared with 3,655 designees working for companies on the FAA's behalf, according to government data.

Boeing has set up a separate group within the company to do the FAA work. Those employees approve the design of the planes except for the key steps and the final "type certificate" for new aircraft, which needs a stamp from FAA officials.

The jobs command respect and draw veterans who are more likely to stand up to pressure from their employers and won't risk losing their "ticket" - the FAA designee status - by cutting corners, people in the industry say. Candidates choose specializations and typically must pass written and oral exams meant to check their understanding of what a designee, also known as a "designated engineering representative" (DER), does and the limits of their powers.

"I've never seen it where a company's pressure on the DER was strong enough for them to bend from their loyalty to the FAA," said Richard Lukso, the former president of Securaplane, the company that made the chargers for the 787 batteries. They have unique insight into how companies work, he added, since they come from the inside.

A WATCHDOG BARKS

In 2011, the DOT's Office of Inspector General criticized the FAA for losing control of its oversight and risking safety. It cited one company designee, acting on behalf of the FAA, who took his employer's view in a dispute over whether an aircraft fuel system met agency standards. The manufacturer took a year to suspend the employee from FAA duty. The company was not identified in the report.

The FAA and the inspector general do not agree on how to weed out unwanted designees. The FAA says it is creating a new database of employees removed from consideration because of "misconduct"; the inspector general's office wants a broader set of employees to be included.

The FAA has been criticized beginning early in the Dreamliner program for skimping on supplier visits, as well.

In the first four years of the Dreamliner program, between 2003-2007, FAA officials visited only 1 percent of suppliers at Boeing and other major engine and plane makers, and left unchecked thousands of factories that would go on to make parts for the 787, according to another report by the same Office of Inspector General, this one from 2008. All parts for U.S. planes must be FAA certified at some point, but that can happen as part of the final assembly of a plane rather than at the factories where they are made.

The same report described how a worker at one factory - it is unclear if it was a supplier to Boeing or another plane maker - used a piece of paper, instead of a ruler, to measure parts. Another used a tool marked "uncalibrated." One supplier made a part fit by grinding away an edge, without permission from the manufacturer, and training overall was deemed inadequate.

The FAA made a number of changes in response to the report, but it only raised the minimum number of supplier visits at major manufacturers to nine a year from four, a spokesman for the inspector general told Reuters.

All FAA inspectors are based in the United States, even though much of the 787 airframe and many key components like the battery are made outside the country, raising the question of whether distance might make them less likely to visit. Inspectors travel when necessary, the FAA said. In its own statement, Boeing said that "in addition to requiring frequent and detailed progress reporting, during the development and design phase we regularly had people on site with our suppliers and they had people on site with Boeing."

FLAMMABILITY TESTS APPROVED

No full description of the process by which Boeing engineered and tested its lithium-ion battery has been disclosed, but emerging details show how regulators relied heavily on Boeing to do most of the work on what the FAA acknowledged from the start would be a potentially dangerous technology.

The FAA approved "special conditions" for the 787 battery in 2007, acknowledging risks including "Flammability of Cell Components."

"Safe cell temperatures and pressures must be maintained during any foreseeable charging or discharging condition and during any failure of the charging or battery monitoring system not shown to be extremely remote," the first condition reads. "Extremely remote" is FAA code for once in 10 million flight hours.

Special conditions do not include specific tests, so Boeing itself proposed them to the FAA. Designees could approve the design of tests and monitor the tests themselves, though the FAA told Reuters its staff also had approved the testing program and observed testing.

A Boeing presentation in February described "baking the battery to induce overheating, crush testing and puncturing a cell with nail to induce short circuit."

At the same time the FAA approved the special conditions in 2007, FAA staff and the aircraft manufacturing industry, including Boeing, were devising lithium-ion battery tests that included all the details the special conditions lacked.

Published in 2008 and adopted by the FAA three years later, the standard known as RTCA DO-311 gave precise instructions for tests. The worst-case-scenario test required turning off all failsafe electronics, short-circuiting the battery and watching for flames for three hours.

Boeing did not run those tests. "The RTCA standards were not designed for the 787," and Boeing provided extensive testing to show the 787 met the special conditions, spokesman Marc Birtel said.

The FAA acknowledged the batteries were potentially flammable in the special conditions approved. Said former Inspector General Schiavo, "They knew they had problems. They just said 'OK.'"

Where did that Russian meteor come from? Astronomers determine origins.

Relying on the many publicly available videos of the meteor that exploded over Russia's Ural Mountains earlier this month, a pair of Colombian astronomers say that they have calculated the space rock's orbit.

By Nancy Atkinson,?Universe Today / February 27, 2013

This dashcam video frame grab shows a meteor streaking across the sky of Russia?s Ural Mountains earlier this month.

Nasha gazeta/www.ng.kz/AP/File

Just a week after a huge fireball streaked across the skies of the Chelyabinsk region of Russia, astronomers published?a paper?that reconstructs the orbit and determines the origins of the space rock that exploded about 14-20 km (8-12.5 miles) above Earth?s surface, producing a shockwave that damaged buildings and broke windows.

Researchers Jorge Zuluaga and Ignacio Ferrin at the University of Antioquia in Medellin, Colombia used a resource not always available in meteorite falls: the numerous dashboard and security cameras that captured the huge fireball. Using the trajectories shown in videos posted on YouTube, the researchers were able to calculate the trajectory of the meteorite as it fell to Earth and use it to reconstruct the orbit in space of the meteoroid before its violent encounter with our planet.

The results are preliminary, Zuluaga told Universe Today, and they are already working on getting more precise results. ?We are working hard to produce an updated and more precise reconstruction of the orbit using different pieces of evidence,? he said via email.

But through their calculations, Zuluaga and Ferrin determined the rock originated from the Apollo class of asteroids.
?
Using triangulation, the researchers used two videos specifically: one from a camera located in the Revolutionary Square in Chelyabinsk and one video recorded in the a nearby city of Korkino, along with the location of a hole in the ice in Lake Chebarkul, 70km west of Chelyabinsk. The hole is thought to have come from the meteorite that fell on February 15.

Zuluaga and Ferrin were inspired to use the videos by Stefen Geens, who writes the?Ogle Earth blog?and who pointed out that the numerous dashcam and security videos may have gathered data about the trajectory and speed of the meteorite. He used this data and Google Earth to reconstruct the path of the rock as it entered the atmosphere and showed that it matched an image of the trajectory taken by the geostationary Meteosat-9 weather satellite.

But due to variations in time and date stamps on several of the videos ? some which differed by several minutes ? they decided to choose two videos from different locations that seemed to be the most reliable.

From triangulation, they were able to determine height, speed and position of the meteorite as it fell to Earth.

This video is a virtual exploration of the preliminary orbit computed by Zuluaga & Ferrin

This is a virtual exploration of th epreliminary orbit computed by Zuluaga & Ferrin (2013). Scientific details can be found at arxiv:1302.5377

But figuring out the meteroid?s orbit around the Sun was more difficult as well as less precise. They needed six critical parameters, all which they had to estimate from the data using Monte Carlo methods to ?calculate the most probable orbital parameters and their dispersion,? they wrote in their paper. Most of the parameters are related to the ?brightening point? ? where the meteorite becomes bright enough to cast a noticeable shadow in the videos. This helped determine the meteorite?s height, elevation and azimuth at the brightening point as well as the longitude, latitude on the Earth?s surface below and also the velocity of the rock.

?According to our estimations, the Chelyabinski meteor started to brighten up when it was between 32 and 47 km up in the atmosphere,? the team wrote. ?The velocity of the body predicted by our analysis was between 13 and 19 km/s (relative to the Earth) which encloses the preferred figure of 18 km/s assumed by other researchers.?

They then used software developed by the US Naval Observatory called NOVAS, the Naval Observatory Vector Astrometry to calculate the likely orbit. They concluded that the Chelyabinsk meteorite is from the Apollo asteroids, a well-known class of rocks that cross Earth?s orbit.

According to?The Technology Review blog, astronomers have seen over 240 Apollo asteroids that are larger than 1 km but believe there must be more than 2,000 others that size.

However, astronomers also estimate there might be about 80 million out there that are about same size as the one that fell over Chelyabinsk: about 15 meters (50 feet) in diameter, with a weight of 7,000 metric tons.

In their ongoing calculations, the research team has decided to make future calculations not using Lake Chebarkul as one of their triangulation points.

?We are acquainted with the skepticism that the holes in the icesheet of the lake have been produced artificially,? Zuluaga told Universe Today via email. ?However I have also read some reports indicating that pieces of the meteoroid have been found in the area. So, we are working hard to produce an updated and more precise reconstruction of the orbit using different pieces of evidence.?

Many have asked why this space rock was not detected before, and Zuluaga said determining why it was missed is one of the goals of their efforts.

?Regretfully knowing the family at which the asteroid belongs is not enough,? he said. ?The question can only be answered having a very precise orbit we can integrate backwards at least 50 years. Once you have an orbit, that orbit can predict the precise position of the body in the sky and then we can look for archive images and see if the asteroid was overlooked. This is our next move!?
