作為世界上最(zui)重要的(de)(de)恐(kong)龍(long)(long)(long)產地(di)之(zhi)一,中國(guo)的(de)(de)恐(kong)龍(long)(long)(long)化(hua)石(shi)發(fa)(fa)現地(di)遍(bian)及東(dong)西南(nan)北。云南(nan)、四川、山東(dong)、內蒙、新(xin)疆等地(di)都以(yi)出(chu)土了(le)大量的(de)(de)恐(kong)龍(long)(long)(long)化(hua)石(shi)而聞名于世。與這些恐(kong)龍(long)(long)(long)大省(sheng)相比(bi),黑(hei)龍(long)(long)(long)江簡直(zhi)有點兒“默默無聞”了(le)。可是(shi)你知道嗎?中國(guo)最(zui)早(zao)被科學地(di)命名的(de)(de)恐(kong)龍(long)(long)(long)化(hua)石(shi)卻(que)正是(shi)發(fa)(fa)現在(zai)黑(hei)龍(long)(long)(long)江畔(pan)的(de)(de)一個(ge)小漁村附近,這個(ge)小漁村就是(shi)嘉蔭縣(xian)的(de)(de)漁亮子。
由于黑龍(long)(long)江水的(de)長期侵蝕(shi),沿江兩岸的(de)地(di)(di)層不斷(duan)地(di)(di)被剝(bo)蝕(shi),里(li)面埋(mai)藏(zang)的(de)恐龍(long)(long)化石就不斷(duan)地(di)(di)被沖刷(shua)出來,暴(bao)露在江邊的(de)河灘(tan)上。當地(di)(di)的(de)漁(yu)民發現了(le)這些化石后非常驚奇(qi),因為(wei)他們(men)從(cong)來沒有(you)見(jian)過這么粗大的(de)動物骨骼。消息不脛而走,被對岸的(de)俄國(guo)軍官聽(ting)到(dao)了(le),就前來調查并采集化石。最初,俄國(guo)人(ren)把這些大化石骨頭(tou)誤認為(wei)是(shi)猛犸(ma)象,而且(qie)在俄國(guo)伯力(li)地(di)(di)方報紙上作了(le)報道。俄國(guo)地(di)(di)質(zhi)學家(jia)被這一報道所吸(xi)引,從(cong)1915年(nian)(nian)至1917年(nian)(nian)連續到(dao)我(wo)國(guo)進(jin)行了(le)三年(nian)(nian)的(de)大規模(mo)考察和發掘,采集到(dao)一批恐龍(long)(long)化石。他們(men)把采到(dao)的(de)化石進(jin)行了(le)修(xiu)理(li),并配上三分之一的(de)石膏模(mo)型,把這些化石裝架起(qi)來,陳列到(dao)彼得堡地(di)(di)質(zhi)博(bo)物館里(li)。研(yan)究(jiu)認定(ding),這是(shi)一種鴨(ya)嘴龍(long)(long),高4.5米(mi),長約8米(mi),俄國(guo)地(di)(di)質(zhi)學家(jia)把它(ta)命名(ming)為(wei)滿洲(zhou)龍(long)(long)。
