脊椎動物 Vertebrates

  約三億七千萬年前(泥盆紀),第一個生活在陸上的脊椎動物,屬於兩棲類的魚石螈(迷齒類),牠們由魚類進化而來,其後並逐漸演化為真正陸生的爬行動物。到了約二億五千萬年前(三疊紀),除新出現的龜鱉類外,更重要是槽齒類爬行動物的出現,牠們進化出恐龍,而哺乳動物亦於三疊紀晚期由其中一支爬行動物演化出來,但早期的哺乳類體型相當小,數量亦不多。而世上最早的鳥類(始祖鳥)出現於一億五千萬年前(侏羅紀晚期),早期的鳥類化石還帶有恐龍的特徵,但牠們的化石相當稀少。
  稱雄一時的爬行動物恐龍於六千五百萬年前(白堊紀晚期)統統都滅絕了,闖過此關而殘留至今的只鱷類、龜鱉類、蛇和蜥蜴等少數類。隨著地史進入新生代(六千五百萬年前至今),新興的哺乳動物取代了爬行動物的位置,牠們向不同方向演化,種類繁多,少數延存至今。
