运用CT扫描技术对鳄龙科的孙氏伊克昭龙的鼻腔部位进行了连续扫描 ,结果显示了该类动物鼻腔构造非常复杂 ,分为两个部分 :后上部分具有嗅觉的功能 ,大的前下部分具有调节体温的功能 ;它的松果体系统的部分丧失 ,显示了它可能具有向内温演化的趋势 .因此 ,该类动物可能具有较强的体温调节能力 ,使其体温与周围环境的温度相适应 ,从而保持高的活动水平 .但它还不足以使其体温像鸟类和哺乳类那样保持恒定 .
The CT scan technique was used to scan the nasal cavity of Sun Ik Zhaolong in Cnooniaceae. The results showed that the nasal cavity of this species is very complex and divided into two parts: the upper part has olfactory function, The lower part has the function of regulating body temperature; its partial loss of the pineal system shows that it may have a tendency to evolve inwardly, so that such animals may have a strong thermoregulation ability to associate their body temperature with their surroundings To maintain a high activity level, but not enough to keep its body temperature constant like birds and mammals.
