求翻譯：Mammals evolved more than 200 million years ago, during the Triassic period, and monotremes were among the first (the very earliest mammals or mammal-like animals have since died out). Placental and marsupial mammals appeared during the Jurassic, sometime between 200 million and 160 million years ago.是什么意思？ 待解決
