The reason: ectotherms range from food sources like insects to top predators like snakes and crocodiles, the loss of which would have ´major flow-on effects, ´ Shine says.

其原因是：像蛇和鳄鱼等变温动物排列在食物来源如昆虫的顶部，将会产生重大的影响。

Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms.

因为恐龙属于爬行动物，而现代的爬行动物都不属于恒温动物，所以长期以来恐龙都被当做是变温动物。
