Paul Sereno with Raptorex

In August of 2011, Paul Sereno posed for an impromptu photo with the Raptorex model his team assembled for the Center in Beijing.

Raptorax, a 2.6-meter long meat-eating dinosaur, lived 125 million years ago in what is now northeastern China.  Raptorex had evolved all of the key anatomical features of its famous descendant Tyrannosaurus, including a large head compared to its torso, tiny two-fingered forelimbs and lanky legs well-suited for pursuit of prey.  A cast of its brain from the inside of the skull shows that, like Tyrannosaurus, it also had an enlarged “smell brain” (olfactory bulbs).

盗龙身长2.6米,属食肉类恐龙,1.25亿年前生活在今天中国的东北,它已经演化出其著名后代霸王龙的全部主要解剖特征,包括一个跟他的躯干相比过大的脑袋、带有双指的短小前肢,和非常适合追捕猎物的细长的双腿。颅内模型显示,与霸王龙相似,盗龙也有一个扩大的“脑嗅觉区”(嗅球)。
