Platypus Dinosaur: A Vegetarian T. Rex

first_img(Visited 166 times, 1 visits today)FacebookTwitterPinterestSave分享0 A new dinosaur from Chile is as unbelievable as the first reported platypus was to English zoologists: a crazy mix of animals.Meet Chilesaurus: a theropod from Chile that looks like a combination of other dinosaurs: a small vegetarian T. rex with a long neck and two-fingered arms. Martin Ezcurra, one of the paleontologists who announced the find in Nature, explains in The Conversation how they identified this “weird and wonderful” dinosaur as a new species:Its skull and neck look like those of primitive long-necked dinosaurs like Plateosaurus; the vertebrae resemble those of primitive meat-eating theropods such as Dilophosaurus; the pelvis is very similar to that of ornithischian dinosaurs such as Iguanodon; and the hand has only two well-developed fingers as in Tyranosaurus [sic] Rex, but with a longer arm.However, there is no possibility that Chilesaurus is simply made up of different dinosaur bones, because we found four partial skeletons. Working partly in Buenos Aires, Argentina, and partly in Birmingham, our team compared the bones to those of other dinosaur groups. Eventually we decided through different analyses that Chilesaurus belongs to a completely unknown lineage of dinosaurs that acquired herbivore habits from carnivorous ancestors. Chilesaurus is the first herbivorous theropod (a lineage that includes mainly predatory dinosaurs) from the southern hemisphere.Ezcurra likens it to the famous platypus that had some incredulous zoologists thinking at first it was a hoax. How can evolution explain such a mosaic of features?A bizarre combination of features like that seen in Chilesaurus can also be seen in living animal species, such as the platypus, which is a mix of duck, beaver and otter. Some naturalists even considered it a hoax. But animals such as Chilesaurus and the platypus can be explained by an evolutionary process called convergence evolution, in which two unrelated species or groups acquire similar characteristics because of living in similar environments or having a similar behaviour.Similarly, the bizarre anatomy of Chilesaurus will probably open a heated discussion about its relationships. Ultimately, the discovery reveals how much data is still completely unknown about dinosaurs and that there is still much waiting to be discovered in the rocks that tell the story of our planet in deep time.The new dinosaur was also reported by Live Science, Science Daily, and Science Magazine, complete with colorful artwork.How do they know that carnivorous dinosaurs did not get their meat-eating habit from vegetarian ancestors? How do they know the coloration of its skin? If there is “much data still completely unknown about dinosaurs” then we don’t need the fake confidence about this one, or about “the story of our planet in deep time.” Did Ezcurra see deep time? Did he see “convergence evolution”? No. He saw beautifully designed bones embedded in rocks. Spare us the storytelling.For more on the improbability of convergent evolution, see the 4/20/15 entry.last_img read more

Kashmir is Pakistans jugular vein PM Imran

first_imgIslamabad: Kashmir is Pakistan’s “jugular vein” and India’s decision to alter its special status poses challenges to the country’s security and integrity, Prime Minister Imran Khan said on Friday. Prime Minister Khan in his message on Pakistan’s Defence and Martyrs Day said his government has launched a proactive diplomatic campaign in the world capitals and at the United Nations to apprise the world community about Kashmir after India revoked Jammu and Kashmir’s special status on August 5.

Altering its status poses challenges to Pakistan’s security and integrity,” Khan said. “I have also urged upon the international community to seriously consider the safety and security of India’s nuclear arsenal… this is an issue that impacts not just the South Asian region but the whole world,” he said.

Tensions between India and Pakistan have spiked after New Delhi withdrew Jammu and Kashmir’s special status and bifurcated it into two union territories on August 5. Asserting that abrogation of Article 370 was its internal matter, India has strongly criticised Pakistan for making “irresponsible statements” and provocative anti-India rhetoric over issues internal to it. Pakistan Army chief Gen. Qamar Javed Bajwa who addressed the main ceremony at the General Headquarters in Rawalpindi said Kashmir was the “unfulfilled agenda” of the completion of Pakistan. “I want to make it clear that Kashmir is the unfulfilled agenda of the completion of Pakistan. It will remain so until it is a resolved according to the UN resolutions,” he said. Bajwa said Pakistan had won its battle against terrorism and was now fighting to end poverty and backwardness. “Today there is a better environment of peace in Pakistan and the country gives the message of peace and security to the world,” he said. “Pakistan has fulfilled its responsibilities in the war on terrorism and now responsibility rests with the world community to full its responsibility and reject all forms of terrorism and extremism. Our fight now is against poverty, unemployment and economic backwardness after successfully confronting the menace of terrorism,” he said.last_img read more

Remembering Skookum Jim who codiscovered Klondike Gold Rush

He willed a lot of funds ahead for his descendants,” said Georgie Low.But often his name has been left out of the history books and credit has been given to George Carmacks, an American miner.“You don’t see Skookum Jim’s name in there a lot. There is just brief mentions … that’s why this interpretive centre is important. We really tell the story of Skookum Jim here,” said Richard Zaidan of Parks Canada.In 1904, he sold his gold claims for $65,000 and continued to live in Carcross until his death in 1919.His trust fund continues to fund local social and education programs for many Yukon First [email protected]last_img read more

Ohio State junior forward Mason Jobst (26) and redshirt sophomore defenseman Wyatt Ege (7) fight for possession of the puck in the first period of the game against Wisconsin on Feb. 23 in the Schottenstein Centern. Credit: Jack Westerheide | Photo EditorOhio State head coach Steve Rohlik always talks about how tough it is to win college hockey games. It would be tough to come away with that impression watching Ohio State with 21 wins in 34 regular-season games this season.The No. 6 Ohio State men’s hockey team (22-8-5, 15-8-2-1 Big Ten) added another win Friday, using a strong special teams performance to push the team to a 6-2 win against Michigan State (12-21-2, 6-17-2-1 Big Ten) at the Schottenstein Center in the first game of the Big Ten tournament matchup.Rohlik knows the win is huge for his team, but that it will feel even bigger if his team earns another victory on Saturday.“It’s very difficult to win at this level, especially against teams like [Michigan State], with our league, Rohlik said. “You know it’s a best two out of three, to get that first win, basically it just gives you the one-up, but that just means you are going to get their best effort tomorrow.” The Buckeyes had three points from junior forward Mason Jobst, as well as two points from sophomore forward Tanner Laczynski and redshirt sophomore defenseman Wyatt Ege. Redshirt junior goalie Sean Romeo added 18 saves on 20 shots in the win.Special teams were key for the Buckeyes. The nation’s best penalty kill went 2-for-2, while the Buckeye power play took advantage of a Spartan penalty kill that is fourth-worst in the NCAA at 76 percent, going 3-for-5 on the night.“I think it’s just executing and I think the guys just decided-we just don’t want to sit back, we kind of got to take it to them, and whoever you play,” Rohlik said. “I think that was the attitude right now, tonight, with our power play. I think that translated into the game.” Two of the three Buckeye power-play goals came early after the penalty was called, each coming just 10 and eight seconds into the power play chances.  “The key is just giving it to our forwards,” Ege said. “As you can tell like, [ Laczynski] and [Jobst], they’re good, just give them and they’re gonna make some stuff happen.”   Laczynski benefited from a lethal Buckeye power play and now has four points in his past three games. The Buckeyes’ top scorer is finding his game in a crucial part of the year.“This is the time you need to be playing your best hockey,” Laczynski said. “Even though I had that slump, like you said, I’m happy to be playing some of my best hockey here and come playoffs. It’s a big game and a big win”  The first period began with a lethargic stalemate, but the intensity and physicality picked up, resulting with a roughing call to Spartan senior defenseman Carson Gatt. That gave Ohio State its first power play chance on the night with 1:28 remaining in the period. On the power-play chance, Laczynski fired a shot from the top of the right circle through a maze of players and past sophomore goaltender John Lethemon for the game’s opening score.The Spartans got on the board just 3:12 into the second period when sophomore forward Patrick Khodorenko gathered a bouncing puck in the slot, firing it over the right shoulder of Romeo to even the score.The Buckeyes took another shot on the power play and converted. Laczynski threw the puck to the goal and senior forward Matthew Weis directed it past Lethemon to regain the lead with 3:28 remaining in the period.The Buckeyes added goals from Jobst and junior defenseman Sasha Larocque in the third, chasing Lethemon from the net.Spartan senior goaltender Ed Minney came in relief of Lethemon, but couldn’t stop two more Buckeye goals. The Spartans and Buckeyes traded late goals for the final of 6-2.Shots were 40-20 in favor of Ohio State. Lethemon made 25 saves on 29 shots and Minney made nine saves on 11 shots in a losing effort. The Buckeyes have a chance to advance to the Big Ten semifinal game if they beat the Spartans in the second contest of the three-game series at 7 p.m. Saturday at the Schottenstein Center. read more
