For most of the last century, experts have agreed that China golf umbrellas theropods were more closely related to a third major evolutionary branch, the Sauropods, that included long-necked beasts such as Diplodocus and Brachiosaurus.The impact probably created a massive firestorm followed by a decades-long winter that destroyed vegetation, the starting point in the dinosaurs food chain.."We realised that it was not a strange, early plant-eating theropod, but rather a strange plant-eating animal that was an offshoot of this other group, Oithischia," Barrett said.

A revised assessment of the kangaroo-sized Chilesaurus, reported in the joual Biology Letters, bolsters a theory unveiled earlier this year that threatens to upend a long-standing classification of all dinosaurs.Most theropods were wiped out too, although the forerunners of mode birds persevered.An oddball, vegetarian dinosaur with the silhouette of a flesh-ripping velociraptor, whose fossilised remains were unearthed in southe Chile 13 years ago, is a missing link in dino evolution, researchers said."Chilesaurus gives us more confidence that this rearrangement was correct because it has a combination of features found in those two groups.Well-known oithischians include Triceratops and the three-tonne Stegosaurus, which boasted large armoured plates along its spine and a brain the size of a walnut."Chilesaurus genuinely helps fill an evolutionary gap between two big dinosaur groups," said co-author Paul Barrett, president of Britains Palaeontographical Society and a researcher at the Natural History Museum."Chilesaurus initially looked like an earlier offshoot of the theropod line, but it seemed suspicious that it had all these adaptations for eating plants," Barrett told AFP.It lived about 150 million years ago, far earlier than the handful of theropods known to have tued away from meat, he pointed out.

When first presented to the world in 2015, Chilesaurus -- despite its penchant for plants -- was lumped together with theropods, the suborder of meat-eating dinos that not only includes fleet-footed velociraptors but Tyrannosaurus rex, the ultimate caivore.Oithischia thrived for more than 100 million years, but dead-ended when the rogue rock smashed into what, today is the Yucatan peninsula in Mexico.But the new affiliation has major implications.Common ancestor To verify Chilesaurus place in the dino family tree, Barrett and Matthew Baron of the University of Cambridge analysed more than 450 anatomical features of early dinosaurs.Dinosaurs were the monarchs of Earth for 160 million years until a space rock collided with the planet 65.This was the bold theory that Baron and Barrett, along with other colleagues, proposed in a landmark study published last March in the joual Nature."Our reorganisation was putting Oithischia and theropods much closer together, and this new animal helps cement that relationship," Barrett explained."An upright posture, powerful hind legs and foreshortened front limbs were all reminiscent of theropods.What they found confirmed a hunch.

The new findings support the idea that theropods and oithischians shared a common ancestor as early as 225 million years ago, not long after the dino saga began.Reassigning Chilesaurus to a new family tree might seem like something only a dino lover could find exciting.But the neither-fish-nor-foul Chilesaurus shows that the fearsome killers under the theropod umbrella shared, in fact, a greater affinity with the docile Oithischia menagerie.Experts acknowledged at the time, however, that it was an awkward fit. One described the beast as "the most bizarre dinosaur ever found.The survivors, which could fly, are the direct ancestor of todays birds."The first dinosaur emerged some 228 million years ago.But an inverted, bird-like hip structure and flattened, leaf-shaped teeth -- proof of an exclusively vegetal diet -- suggested that it also shared traits with another major suborder, the Oithischia.5 million years ago and wiped out those confined to land.

U..In the early-2000s, the EU sought (unsuccessfully) to emerge from the US Cold War umbrella.S.  Putin’s recent moves indicate Russia is equally willing to make the required compromises. President-elect Trump insists that Russia can help the US in tackling conflicts in West Asia and other challenges, the anti-Russia rhetoric is becoming even shriller.A US-Russia reset can also permit a Russia-Japan reconciliation – a process summarily arrested in 2014 by G7 sanctions against Russia; tentatively recommenced this year.A key determinant for success in this new strategic direction would be the President’s ability to carry his Administration with him.No foreign personality has ever figured as prominently in a US Presidential campaign as Russian President Putin.He asserts that ISIS is a greater threat than Assad and that perfidious Weste actions promoted extremism and terrorism, and sucked U.

The Russia-West acrimony and the conflicts in West Asia provided the defence industry, export outlets to compensate for falling US defence budgets. A robust Russia-Japan partnership can be a powerful counterweight to China in the Asia-Pacific.His argument on Russia is that, instead of exaggerating an "existential" threat from a waning superpower, U. If Trump translates into policy his view that fighting ISIS is more important than deposing Assad, and arrives at a common US-Russia approach, not only on Syria, it could have a dramatic impact, not only on Syria, but also on other conflicts in the region. The question is whether his Administration can translate this into coherent policy.This then is the compelling strategic argument for the US to reverse its course of confrontation with Russia, which mainly benefits China and the countries whose interests clash with those of the US. For all his alleged ignorance of foreign policy, President-elect Trump has grasped this reality.So, can a US-Russia thaw usher in some new geopolitical trends in 2017?Trawling through his many pugnacious remarks and earthy tweets, we can disce major elements of President-elect China golf umbrellas Trump’s geopolitical perspectives:His signature, ‘Make America Great Again’, is straight out of the neoconservative playbook.

The appointment of Exxon CEO Tillerson as Secretary of State draws attention to US interests in Russia’s hydrocarbons industry.Such a realignment of US foreign policy would – depending on its course – largely accord with India’s strategic interest. He is portrayed as a malevolent figure who influenced recent Presidential elections, threatens the US with nuclear weapons, unleashes a bloodbath in Aleppo and is disrupting world order by redrawing national borders. And address the widespread image of Russia as the "existential threat".S.In short, therefore, President Putin could be a trump card in President Trump’s effort to align US foreign policy with its strategic interests. As U.The storm of outrage at these assertions reflects the apprehensions of the multiple constituencies which feel threatened by their implications. into a morass. It would be in US strategic interest, but does not require US political or economic investment, only its acquiescence. should focus on the real threat from an assertive China, and co-opt Russia in this effort. It is in obvious US strategic interest that its firms (and not those of China) expand their presence in Russia’s Arctic. The "Normandy Four" of Germany, France, Russia and Ukraine has been negotiating its resolution.The author is former Ambassador to Russia.

The immediate challenge comes from the crisis in Syria. Thus, collaboration with China benefits US business; hostility to Russia benefits its defence industry. The first challenge is to align commercial interests with strategic interests. Corporate and financial institutions have benefited from Chinese connections.S. The contra-image —Fareed Zakaria’s recent description of China as a "relatively benign" power — is a strange description for a country that challenges US strategic interests, flaunts its military power, captures a US Navy drone in inteational waters and imposes strict limits on the nature and level of diplomatic engagement with the Dalai Lama or Taiwan. Russia needs technology for exploitation of offshore Arctic resources. In recent years, these commercial interests have trumped strategic thinking. remains a phantom presence and Europeans (and Russians) have privately blamed US interference for continued impasse. The Ukrainian crisis however mars Russia-Europe relations. If a US-Russia thaw materialises, that opportunity arises again.S.
