10 Second Trivia. What region is bordered by the Andes Mountains, the Colorado River and the Atlantic Ocean? Balkan Peninsula, Amazon Basin,Patagonia or Western Plateau. The only option here that's surrounded by all these features is Patagonia, a region in Argentina.

10秒快速问答。哪个地区以安第斯山脉、科罗拉多河和大西洋为边界?巴尔干半岛，亚马逊盆地，巴塔哥尼亚还是西部高原?被所有这些包围的唯一选择是位于阿根廷的巴塔哥尼亚地区。

If you thought dinosaur names peaked with Titanasaurs. Let's talk about ninjatitan. It sounds so big and stealthy at the same time. Ninjatitan zapatai is what researchers are calling some fossils recently found in Argentina. The skeleton is incomplete and there's a lot that's still unknown about this animal.

如果你认为恐龙名字的顶峰是泰坦龙。那么我们来谈谈忍者龙。它听起来很大，同时又很隐蔽。研究人员称最近在阿根廷发现的一些化石为忍者龙。化石的骨骼是不完整的，对于这种动物还有很多未知的地方。

But paleontologists believe that ninjatitans were sauropods with bodies like brontosaurus. Think long necks, thick legs and the length of about 65 feet. They're not the titanosaurs. One of them named argentinasaurs is thought to have been as long as 115 feet.

但古生物学家认为忍者龙是像雷龙一样身体的蜥脚类动物。长长的脖子，粗腿大约为65英尺。它们不是泰坦龙。其中一种被命名为阿根廷龙的恐龙，长达115英尺。

But scientists say the recently discovered fossils are older than those of other types of titanosaurs and that suggests that ninjatitans might have pre-dated other dinosaurs that looked like them. The region of Patagonia in southern Argentina has been an epicenter of dino discoveries.

但科学家们表示，最近发现的化石比其他类型的泰坦龙化石更古老，这表明忍者龙可能比其他看起来像它们的恐龙更早出现。阿根廷南部的巴塔哥尼亚地区是恐龙发现的中心。
