人民網東京4月27日電(吳穎)據《朝日新聞》報道,日本國立博物館與阿根廷國立科學博物館等組成的研究小組在阿根廷發現大型食肉恐龍化石,判斷為新的恐龍物種,并在科學雜志上發表了這一研究成果。研究小組根據當地傳說中出現的惡靈“邁普”的名字,將其命名為“邁普·麥克索拉克斯”(音譯)。

據悉,該研究小組于2020年3月在阿根廷南部圣克魯斯省從大約7千萬年前的地層中發現了脊椎骨和肋骨等部分骨頭,從骨頭的形狀和骨密度等特征判斷為新物種。

據推測,該恐龍活著時全身有長9米,體重有5噸。其身體的寬度從骨頭推測約有1.2米,可見其體型很結實。目前還未發現其頭部,調查將繼續進行。

據悉,新恐龍物種化石將于2023年在日本國立科學博物館舉辦的特別展“恐龍博覽會2023(暫稱)”上公開展出。
