1·For years, we have assumed it was the abundant plant life of the Mesozoic that allowed these giants to thrive.
多年来，我们一直认为是中生代丰富的植物种类使这些巨型生物得以繁衍生息。
2·The Phanerozoic is divided into three eras — starting with the earliest, these are the Paleozoic, Mesozoic, and Cenozoic.
显生宙可划分为三个时期——依次经历古生代、中生代和新生代。
3·It is thus possible that the same was applicable to Mesozoic predators as well.
于是中生代的食肉动物也可能是这样。
4·The rift development slowly halted some 250 to 245 million years ago, around the beginning of the Mesozoic Era.
这些裂缝的活动在大约2.5-2.45亿年前，即中生代初期逐渐停止了。
5·As Naish points out, though, the new findings about Samrukia demonstrate that modern birds "weren't as distinct from extinct groups of Mesozoic birds as people used to think."
Naish指出，关于Samrukia的新发现证明了现代鸟类与已灭绝的中生代鸟类种群的不同程度并非像人们曾认为的那样。
