AI overview

The Cenozoic Era is Earth's current geological period, spanning the last 66 million years since a massive asteroid impact wiped out the dinosaurs and many other species. It is defined by the rise and dominance of mammals, birds, insects, and flowering plants, making it the age in which modern life as we know it developed.

新生代（しんせいだい、英: Cenozoic era）は、古生代・中生代・新生代と分かれる地質時代、顕生代の大きな区分の一つである。多くの場合は鳥類を除いた恐竜絶滅後を指す。約6,500万年前から現代までに相当し、陸上では非鳥類型恐竜が絶滅し、海中ではアンモナイトと海生爬虫類が絶滅した後、哺乳類が繁栄したことで特徴づけられる。新生代は、第四紀・新第三紀・古第三紀の3つの紀に区分される。また、新第三紀と古第三紀を合わせた地質時代を、非公式な用語として第三紀と呼ぶことが許されている。
