恐龙是冷血动物吗？有最新研究显示，一些恐龙的体温介于摄氏35至40度之间，因此认为恐龙是冷血动物，这可能是错误的观念。

领衔学者罗宾在耶鲁攻读博士学位时从事相关研究，并于上周在《科学进展》发表，“我们的研究结果显示，多数的恐龙体温都比外在环境来得高。”

研究人员分析伤齿龙、慈母龙的蛋壳化石，借由观察化石内的炭、氧原子排序，可算出恐龙妈妈的身体温度。

那么，恐龙是靠当时的环境，还是靠自己维持体温？研究人员再分析与这些恐龙同时期、生活在同一地区的一些冷血软体动物的化石，推断一些软体动物体温约为摄氏26度。

研究人员因此认为，这些恐龙的体温没有随着环境改变，因此并非冷血动物，而是依靠自身新陈代谢维持体温的温血动物。
