2017年已经过去了大半,古生物学家又发现了许多新恐龙。在众多新发现和新命名的恐龙中有一种恐龙吸引了大家的关注,它就是北方盾龙。这种恐龙的化石不仅保存完整,而且化石中表现出来的信息显示它具有“隐身”能力。被洪水埋没的化石距今1.1亿年前的白垩纪早期,连续几天的暴雨袭击了今天加拿大的南部地区。大量雨水导致河流的水位上涨,湍急的河水淹没了沿岸的低洼地带。河边的一片灌木丛本来距离河水足有10多米的距离,但现在已经与河水近在咫尺。 More than halfway through 2017, paleontologists have discovered many new dinosaurs. Among the many newly discovered and newly named dinosaurs, there is a dinosaur that draws everyone’s attention. It is the northern shield dragon. The dinosaur’s fossils are not only preserved, but the information presented in fossils shows it has “stealth” capabilities. Floods buried fossils 110 million years ago, the early Cretaceous, a few days of heavy rains hit today’s southern Canada. Large amounts of rain led to rising water levels in the rivers, and swift rivers flooded low-lying coastal areas. The river’s shrubbery was originally a distance of more than 10 meters from the river, but it is now close to the river.
