《侏罗纪公园》恐龙原型 “美国三角龙”来重庆了
2017-08-06 10:12:28 中国青年网
本报讯 (记者 孔令强)还记得《侏罗纪公园》中的那个美国三角龙吗?“它”来重庆了!昨天上午,《侏罗纪公园》中美国三角龙原型的三角龙头骨化石正式落户璧山,这也是重庆拥有的首个三角龙头骨化石,将在璧山天赐华汤酒店永久免费展出。
三角龙因头上有三个犄角而得名。记者在现场看到,展出的三角龙头骨化石可以很明显地看到三根犄角,再加上颈部的扇状结构,很像大家熟知的犀牛。“三角龙是世界已知的最著名的恐龙之一,大约在距今7000万年前出现,灭绝于6600万年前。”恐龙研究专家、重庆自然博物馆馆长欧阳辉介绍,“三角龙头骨巨大,占到了整个身体比例的三分之一左右,是头骨最大的陆地动物。头上有三个角,短的一根叫鼻角,长的一对叫做额角,后面的扇形结构叫做颈盾。”
欧阳辉告诉记者,三角龙完全的骨架化石非常难得,因为三角龙体型巨大,“死亡后头骨与头后骨骼很容易解体,在长期的地质作用下往往身首异处,所以较难发现完整的骨架化石。”欧阳辉透露,这次落户重庆的三角龙头骨化石的真骨比例达到了75%以上,其中“下颌骨、鼻角、额角以及枕骨等关键部位均为真实骨骼,整个头骨经科学复原呈现了三角龙头骨的完整形态。”
引进该化石的重庆天赐温泉集团董事长杨长林介绍了收藏这件自然标本的全过程,“2017年初,我们得知法国的一家拍卖行要拍卖这件北美洲三角龙头骨化石。”知道这一线索后,杨长林通过多方联系,终于参加了拍卖,经过激烈竞拍,最终竞得了这件头骨化石。
