Europe's largest dinosaur rises from Spanish fields

歐洲頭號(hào)恐龍化石現(xiàn)身西班牙

Farmers in Riodeva cleared stones from their almond orchards for generations, never dreaming they were tossing aside dinosaur bones -- and laying a trail for one of Spain's greatest fossil finds.

But when two paleontologists stumbled across a field scattered with the fragments they knew they had probably found a valuable cache and when digging began in early 2003 it revealed a hoard beyond their wildest hopes.

The remains of the largest dinosaur found in Europe, including an upper limb bone as big as a person -- 5 feet 9-1/2 inches -- were nestling just below the surface in this remote corner of the central Spanish region of Aragon.

"To find lots of bones is amazing. To find such a big animal is extraordinary, and to find it in Europe is extra-terrestrial," said Alberto Cobos, the man who recognized the potential of the site.

The huge reptile, which weighed an estimated 40 to 50 tons, the same as six or seven elephants, probably roamed the region up to 130 million years ago when it was a tropical "dinosaur paradise," crisscrossed with rivers and streams.

Huge, perfectly preserved toe bone fossils and even a single curved nail, larger than a human hand, were found with a rib and leg and possibly pelvic bones.

The herbivore's bones were jumbled with remains from other, smaller animals -- including teeth from carnivores that may have feasted on its flesh.

Up to 114 feet long, the dinosaur could represent a new species, although the team uncovering it is wary of jumping to conclusions -- but its size alone is enough to put Riodeva firmly on the map.

The largest known dinosaurs have been found in Latin America and the new Spanish dinosaur claims the record for Europe, Cobos said.

西班牙里奧德瓦的果農(nóng)們世代為杏園清理石子,可他們做夢(mèng)都沒有想到自己在不斷丟棄恐龍遺骨,并為發(fā)現(xiàn)西班牙最偉大的化石之一提供了線索。

當(dāng)兩位古生物學(xué)家偶然發(fā)現(xiàn)一片散落著這些碎片的田地時(shí),他們意識(shí)到他們可能發(fā)現(xiàn)了一個(gè)珍貴的秘密隱藏處。2003年初,當(dāng)挖掘工作開始時(shí),結(jié)果超出了他們最狂熱的期望,他們發(fā)現(xiàn)了一個(gè)寶庫(kù)。

這是歐洲目前發(fā)現(xiàn)的最大的恐龍殘骸,其中包括一塊長(zhǎng)達(dá)5英尺9.5英寸,差不多有一人長(zhǎng)的上肢骨骼,這些殘骸埋藏在西班牙中部阿拉貢地區(qū)偏遠(yuǎn)角落的地下。

“發(fā)現(xiàn)那么多骨骼是令人驚訝的;發(fā)現(xiàn)這么大的動(dòng)物是極不平常的;而在歐洲發(fā)現(xiàn)它就更像天方夜譚了。”阿爾韋托·科沃斯說(shuō),他意識(shí)到此地潛在的價(jià)值。

這只巨大的爬行動(dòng)物估計(jì)有40到50噸重,相當(dāng)于六七頭大象的體重之和。一億三千萬(wàn)年前,它可能在這片地區(qū)游蕩,當(dāng)時(shí)這里是河流交錯(cuò)的熱帶“恐龍?zhí)焯谩薄?BR>
這里發(fā)現(xiàn)了巨大的、保存完好的足趾骨化石,甚至還有一片比人手還大的彎曲的趾甲,同時(shí)發(fā)現(xiàn)的還有一根肋骨和一條腿,還有一些可能是組成骨盆的骨頭。

這只食草恐龍的骨頭和其他小動(dòng)物的遺骸混雜在一起,其中包括可能曾經(jīng)飽餐過(guò)恐龍尸體的食肉動(dòng)物的牙齒。

這頭體長(zhǎng)達(dá)114英尺的恐龍也許代表著一種新的物種,盡管發(fā)現(xiàn)它的調(diào)查隊(duì)小心翼翼地避免匆忙下結(jié)論,但僅憑它的體格就足以使里奧德瓦在地圖冊(cè)中占有一席之地。

科沃斯說(shuō),拉丁美洲發(fā)現(xiàn)了目前已知的最大的恐龍,這只新發(fā)現(xiàn)的西班牙恐龍創(chuàng)造了新的歐洲記錄。
