In the austral summer of 2004, I went to the bottom of South America, to the bottom of Patagonia, Argentina, to prospect for dinosaurs: a place that had terrestrial sedimentary rocks of the right age, in a desert, a place that had been barely visited by paleontologists.
在2004夏季， 我去到位于南半球南美的最南端， 阿根廷的巴塔哥尼亚最南部， 去探究恐龙： 那儿有特定年代的陆相沉积岩。 在那片还未被古生物学家发掘过的沙漠，
