三畳紀

Also known as Triassic Period, Triassic System

地質時代の一つ、中生代を三分した最初の紀

AI overview

The Triassic is a geologic period that lasted about 50.5 million years, starting 251.902 million years ago after the Permian Period ended and ending 201.4 million years ago when the Jurassic Period began. It matters because it was the first and shortest period of the Mesozoic Era, and both its beginning and end were marked by major extinction events that reshaped life on Earth.

三畳紀（さんじょうき、Triassic period）は、現在から約2億5190万年前に始まり、約2億130万年前まで続く地質時代である。トリアス紀（トリアスき）と訳すこともある。三畳紀の名は、南ドイツで発見されたこの紀の地層において、赤色の砂岩、白色の石灰岩、茶色の砂岩と堆積条件の異なる3層が重畳していたことに由来する。中生代の最初の紀であり、ペルム紀（二畳紀）の次、ジュラ紀の前にあたる。開始および終了の時期は、研究者やその学説によって、いずれも互いに1000万年前後の年代差がみられる。
