基本介紹

作為世(shi)界上(shang)最重(zhong)要的恐(kong)(kong)(kong)龍(long)(long)(long)(long)(long)產地之一，中(zhong)國的恐(kong)(kong)(kong)龍(long)(long)(long)(long)(long)化石(shi)發現地遍及東(dong)西南(nan)北。云南(nan)、四(si)川、山東(dong)、內蒙、新疆(jiang)等地都(dou)以出土了(le)大量的恐(kong)(kong)(kong)龍(long)(long)(long)(long)(long)化石(shi)而聞名于(yu)世(shi)。與這(zhe)些(xie)恐(kong)(kong)(kong)龍(long)(long)(long)(long)(long)大省相比(bi)，黑龍(long)(long)(long)(long)(long)江簡直有(you)點兒“默默無聞”了(le)。可是你知(zhi)道嗎？中(zhong)國最早被科學地命名的恐(kong)(kong)(kong)龍(long)(long)(long)(long)(long)化石(shi)卻正是發現在(zai)黑龍(long)(long)(long)(long)(long)江畔的一個小(xiao)漁(yu)村(cun)附(fu)近，這(zhe)個小(xiao)漁(yu)村(cun)就(jiu)是嘉蔭縣(xian)的漁(yu)亮子(zi)。

由于黑龍(long)江水的(de)(de)長期(qi)侵蝕(shi)，沿(yan)江兩(liang)岸的(de)(de)地(di)(di)層不斷地(di)(di)被剝蝕(shi)，里(li)面(mian)埋(mai)藏的(de)(de)恐龍(long)化(hua)(hua)石(shi)就不斷地(di)(di)被沖刷出來(lai)(lai)，暴露在(zai)江邊的(de)(de)河灘上。當地(di)(di)的(de)(de)漁民(min)發現了(le)(le)這些化(hua)(hua)石(shi)后非常(chang)驚奇(qi)，因為他們從(cong)來(lai)(lai)沒有見過這么粗大(da)的(de)(de)動物骨骼。消息(xi)不脛(jing)而(er)走，被對岸的(de)(de)俄(e)(e)(e)國(guo)(guo)軍官聽到(dao)了(le)(le)，就前來(lai)(lai)調(diao)查并采集化(hua)(hua)石(shi)。最初，俄(e)(e)(e)國(guo)(guo)人把(ba)這些大(da)化(hua)(hua)石(shi)骨頭誤認(ren)為是猛犸(ma)象，而(er)且在(zai)俄(e)(e)(e)國(guo)(guo)伯力地(di)(di)方報(bao)(bao)紙上作了(le)(le)報(bao)(bao)道(dao)。俄(e)(e)(e)國(guo)(guo)地(di)(di)質(zhi)(zhi)學(xue)家被這一報(bao)(bao)道(dao)所吸引(yin)，從(cong)1915年至1917年連(lian)續到(dao)我國(guo)(guo)進行了(le)(le)三年的(de)(de)大(da)規模(mo)考察和(he)發掘，采集到(dao)一批恐龍(long)化(hua)(hua)石(shi)。他們把(ba)采到(dao)的(de)(de)化(hua)(hua)石(shi)進行了(le)(le)修理，并配上三分之一的(de)(de)石(shi)膏模(mo)型，把(ba)這些化(hua)(hua)石(shi)裝架起(qi)來(lai)(lai)，陳列到(dao)彼(bi)得堡(bao)地(di)(di)質(zhi)(zhi)博物館里(li)。研(yan)究(jiu)認(ren)定，這是一種鴨嘴龍(long)，高4.5米，長約8米，俄(e)(e)(e)國(guo)(guo)地(di)(di)質(zhi)(zhi)學(xue)家把(ba)它命名為滿(man)洲龍(long)。
