Largest-ever millipede fossil found 考古學(xué)家發(fā)現(xiàn)有史以來(lái)最大千足蟲(chóng)化石

科學(xué)家表示,他們?cè)谟⒏裉m諾森伯蘭郡的一片海灘上發(fā)現(xiàn)了有史以來(lái)最大的巨型千足蟲(chóng)(又稱(chēng) “馬陸”)化石,該發(fā)現(xiàn)純屬偶然。

The fossil was discovered when a boulder fell and cracked open at Howick Bay in Northumberland. It revealed a 75cm-long section of what's now been identified as an Arthropleura, a giant millipede that lived more than 300 million years ago.

這塊化石是在諾森伯蘭郡豪威克灣的一塊巨石墜裂時(shí)被發(fā)現(xiàn)的。巨石中露出了一段75厘米長(zhǎng)的化石,現(xiàn)已被鑒定為節(jié)胸蜈蚣,是一種生活在三億多年前的巨型千足蟲(chóng)。

Researchers at Cambridge University say that the whole creature would have been about 2.7 metres long -------– that's the same as a small car and could have weighed 50 kilos.

劍橋大學(xué)的研究人員指出,整個(gè)生物全長(zhǎng)大約2.7米,與小汽車(chē)的長(zhǎng)度相同,而且可能重達(dá)50公斤。

Given this Arthropleura's size, it's possible that it ate small invertebrates and even amphibians. Despite its incredible length and name, researchers say this giant millipede had fewer than a hundred legs.

鑒于這種節(jié)胸蜈蚣的體型,它很可能以小型無(wú)脊椎動(dòng)物甚至兩棲動(dòng)物為食。盡管這種巨型千足蟲(chóng)的長(zhǎng)度和名字很不可思議,但研究人員表示它其實(shí)只有不到100條腿。
