Discovery 有一集單元
The Ultimate Guide: T. Rex 細說暴龍
其中一段在強調暴龍的前肢
暴龍頭部變大
以便放置又大又多的牙齒
所以尾部延長以便平衡前後重量
並且重心移至後肢上
也就是臀部的位置
並且前肢縮小
Dr. Philcurrie, from Royal Tyrrell Museum of Paleonyology, said:
If you look at the front limbs of Tyrannosaurus, they have become also extremely short. They were relying on their head to do the killing. The limbs could be shortened up and would give it a great saving in weight on the front end of the body.
