A large fossil primate that lived from the late Miocene to the early Pliocene of the Tertiary Period. Its name means "oak tree monkey". It is said to have once lived in forests and lived an arboreal life. It was discovered by the Frenchman Larté in 1856, and was the first fossil ape to be studied academically. Today, many fossils have been excavated from various parts of Europe, Africa, and Asia, most of which are jaw bones and teeth. Many scholars have attempted to classify these specimens, and they have even been considered to be in the same genus as Sivapithecus and Proconsul. There is a Y-shaped groove on the biting surface of the molar, which is found in the first lower molar of most modern humans, and so it was once considered to be an ancestor of humans. Today, it is thought to be an ancestor of modern great apes, or a close relative of them. [Shise Kahara] Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
第三紀中新世後期から鮮新世初期にかけて生存していた大型の化石霊長類。その名は「ナラの木のサル」を意味する。かつて森にすみ、樹上生活を営んでいたとされる。1856年、フランスのラルテにより発見されたが、学問的に研究された最初の化石類人猿である。今日ではヨーロッパ、アフリカ、アジアの各地から数多くの化石が出土しているが、そのほとんどは顎骨(がくこつ)と歯である。これらの標本は多くの学者により分類が試みられ、シバピテクス、プロコンスルと同属とされたこともあった。大臼歯(きゅうし)の咬面(こうめん)にY字状の溝があり、これが現代人の大部分の下顎第一大臼歯にみられるところから、かつては人類の祖先とみなすむきもあった。今日では現生大型類人猿の祖先、あるいはその近縁のものと考えられている。 [香原志勢] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
