THE DINOSAURS ~230 million years

Dinosaurs were the dominant terrestrial vertebrate animals for over 160 million years, from the late Triassic period, about 230 million years ago, until the end of the Cretaceous period, about 65 Ma, when most of them became extinct in the Cretaceous–Tertiary extinction event. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic period, and most paleontologists regard them as the only clade of dinosaurs to have survived until the present day.

(依照維基 65 Ma = 65 million years ago,不知是真有此縮寫,還是官網文字錯誤?) 

恐龍 ~2億3千萬年前 

恐龍是陸地脊椎動物,稱霸超過1億6千萬年,從三疊紀晚期,約2億3千萬年前,直到白堊紀末期,約6千5百萬年前。絕大多數的恐龍在白堊紀第三紀滅絕事件當中消失了。化石紀錄表明,鳥類在侏儸紀時期從獸腳類恐龍進化而來,大多數的古生物學家認為牠們是恐龍殘存下來的唯一分支,直到今日。
