這朵“南京花”開(kāi)了1.74億年！科學(xué)家發(fā)現世界最古老的花朵化石

　　12月18日，中國科學(xué)院南京地質(zhì)古生物研究所研究員王鑫（左）、副研究員傅強在整理“南京花”化石。電影《侏羅紀公園》或許該改改了——與侏羅紀恐龍同框的，除了高大的蘇鐵、桫欏，還應該加上一抹亮色——鮮花。由中科院南京地質(zhì)古生物所領(lǐng)銜的一個(gè)國際研究團隊，新近在南京東郊發(fā)現了200多塊遠古化石花的標本。研究表明，這些花朵生活的年代距今至少有1.74億年，是迄今為止人類(lèi)發(fā)現的最古老的花朵化石，它們的發(fā)現將被子植物的起源時(shí)間前推大約5000萬(wàn)年?？蒲腥藛T將之命名為“南京花”。相關(guān)研究成果18日發(fā)表在生命科學(xué)領(lǐng)域知名刊物《電子生命》上。新華社記者孫參攝
