ナウマンゾウの分類学上の扱いの変遷はやや複雑ですが、彼らが他の化石長鼻類とは異なる集団と認識され、初めて亜種として記載されたのはちょうど100年前のことになりますね。 (参考: https://t.co/Y7Xvy7gQxY) https://t.co/j9SraUb3HT

先日 #チバニアン期の古生物展 に行ってきたのですが、ナウマンゾウ Palaeoloxodon naumanniのホロタイプ標本【下顎の臼歯】等の実物(!)を観察する事が出来ました♪ ナウマンゾウの原記載論文 Makiyama (1924)https://t.co/bjGx5SDkdT ナウマンゾウ研究百年 高橋 (2022) https://t.co/SJDinlrk19 https://t.co/IRuz0yxQz6
これはじっくり読みたい。ナウマンゾウのレビューが日本語で読めるので勉強するにも良さそうだし、これからどんなことができるのか考えるのにも良さそう。 ナウマンゾウ研究百年 https://t.co/HobJEOWcgr
