摘要
Gigantic herbivorous sauropoda dinosaurs were very huge creatures. Their main evolution was gigantism for having advantage of getting ecological niche, and other evolutions were cooperated with it. The characteristics of sauropoda dinosaurs, for an example: 1) their long neck with a tiny head would have had the ability to browse at many levels and orientation needed not to move their gigantic body often; 2) their large nares would have allowed to breathe air in large throughput to support their gigantic body living, and so they would have had strong blood circulatory system; 3) their spatulate-shaped teeth would have had the ability to stripped longer portions of plant’s stems in a single action, and ingested apace without mastication; 4) their femurs were longer than their tibias, and showed they would have been ineffective runners but their thick legs were powerful, and could stand up to graze on high plants, or to swat enemies; and 5) they were quadrupeds with very wide and large paws, so they would have shared the weight of bodies by the four legs, and reduced pressure to ground.
