[雙語(yǔ)] 美國(guó)驚現(xiàn)恐龍新物種

 

Remains of the newest member of the dinosaurs were discovered recently in the American state of Utah by a team of British and American scientists. Named the Brontomerus Mcintoshi, the creature has been given the nickname "thunder thighs" because of its huge legs. They date from the early Cretaceous period, which began around 145 million years ago and ended 65 million years ago.

日前一隊(duì)由美國(guó)和英國(guó)科學(xué)家組成的科考隊(duì)在美國(guó)猶他州發(fā)現(xiàn)了一種新型恐龍化石。這個(gè)新恐龍隨即被命名為Brontomerus Mcintoshi，并以其壯碩的大腿被冠以綽號(hào)“雷腿”。據(jù)悉，他們最早生活在白堊紀(jì)早期，亦即1億4千5百萬(wàn)年前到6千5百萬(wàn)年前。

The remains included a juvenile's left ilium bone, which forms part of the pelvis, and also a near complete left scapula of a presumably adult. The scientists also found well preserved vertebrae from the creature as well as a complete rib bone.

發(fā)掘出的化石包括一只幼龍的左髂骨（骨盆的一部分），亦即一只疑似成年恐龍的完整的左肩胛骨?？茖W(xué)家們還發(fā)現(xiàn)了保存完好的椎骨以及一個(gè)完整的肋骨。

They used the bones they discovered to match certain known criteria to determine what species of dinosaur they came from. Using five variables, and particularly focused on the size and other factors within the ilium bone, they confirmed it was from the Sauropod family.

科學(xué)家們將這些化石魚(yú)已知恐龍化石進(jìn)行比對(duì)，以確定新發(fā)現(xiàn)恐龍所屬種類(lèi)。進(jìn)行了5組比對(duì)后，尤其是就髂骨的大小等種種因素進(jìn)行分析后，他們確定該恐龍來(lái)自蜥腳類(lèi)家族。
