英国科学家最近通过CT扫描技术重建了重爪龙的结构图。科学家通过计算机建模技术发现,重爪龙的头骨不仅是形态上与鳄鱼十分相似,其进食时的头骨弯曲和伸展与印度食鱼大鳄鱼头骨的反应一致。科学家推测其进食行为与典型的兽脚亚目食肉恐龙或美洲鳄截然不同,它们经常在河边捕捞河鱼为食物。 British scientists recently reconstructed the structure of the heavy claw dragon by CT scanning technology. Scientists found through computer modeling techniques that the skull of the clawed dragon is not only morphologically similar to a crocodile, but its skull flexion and extension during feeding is consistent with that of the crayfish skull of the Indian food fish. Scientists speculate that their eating behavior is quite different from that of a typical ornivorous carnivore dinosaur or the American alligator, who often feed river fish for fishing.
