In terms of the fundamental restructuring of the pterosaur bauplan, the high diversity of food sources from the air (such as feathered dinosaurs, gliding mammals, small pterosaurs and insects) might have been one of the causes responsible for the first evolution of the skull and neck.

从达尔文翼龙的骨骼结构变化上看，空中丰富的食物来源(比如飞行能力差的、带羽毛的恐龙、滑翔的哺乳动物、小的翼龙及昆虫等)，可能为导致翼龙头骨和颈部首先演化的原因之一。

Paleontologists are stunned at the number of species they've dug up, including many previously unknown: A new stegosaur — a tree-grazing sauropod with a nine-meter neck, a new long-toothed pterosaur — a flying reptile, new raptors and even a little mammal-like reptile.

古生物学家对於出土的恐龙种类数量感到惊讶，其中包括许多前所未见的种类：新种剑龙、拥有九公尺长颈，专吃树叶的蜥脚龙、属於会飞爬虫动物，满口长牙的新种翼龙、新种迅猛龙，甚至是状似哺乳动物的小型爬虫动物。

AIM: To observe the effect of solanine on the contents of caspase-3 and Bcl-2 in HepG2, and to explicate the mechanism by which solanine induces the apoptosis of tumor cells. METHODS: Laser confocal scanning microscopy and Western blot were used to measure the contents of caspase-3 and Bcl-2, and LCSM was used to determine their locations in the cell. RESULT: Solanine markedly increased the content of caspase-3 while decreasing that of Bcl-2 in HepG2, both in a dose-dependent way.

目的：观察龙葵碱对HepG2细胞内caspase-3及Bcl-2蛋白含量的影响，阐明龙葵碱诱导肿瘤细胞凋亡的作用机制方法：采用激光共聚焦扫描显微术和Western blot法检测caspase-3和Bcl-2蛋白含量，并对二者在细胞内的位置进行定位结果：龙葵碱能够显著升高跳西2细胞内caspase-3蛋白含量，降低Bcl-2的含量，并且均具有剂量依赖性。

For instance, the dragon in western legends has a lot in common with Chinese dragon: huge body covered by squama and shells all over, four legs with sharp claws, horns, and both can fly in the sky.
