澎湖鱷魚化石 可能改寫歷史
推估距今約1400萬年 暫命名為「潘氏澎湖鱷」
澎湖縣民潘明國上個月在西嶼鄉海邊挖出古鱷魚化石，澎湖縣文化局昨天暫命名為「潘氏澎湖鱷」，以表彰潘明國的文化貢獻；另地質學者勘查化石出土地後，推估這具鱷魚化石距今約1400萬年，是中新世初期生物，可能改寫亞洲古代生物史與地質史。
古鱷魚化石出土後，國立自然科學博物館地質學組研究員程延年跨海鑑定，研判是800萬到1400萬年前「中新世」時期的馬來鱷古化石，由於這是台澎第一次在地層裡發現鱷魚化石，不同於以往在澎湖海溝撈出的鱷魚化石，有助於研究大陸與澎湖陸節相連時的動物遷徙。
學者與澎湖縣文化局人員到鱷魚化石出土現場會勘，發現出土地平時被海水淹沒，海水退潮時才會露出，台大地質學教授魏國彥與程延年等學者從地質層位進一步研判，認為化石年代應是「中新世」時期初期的產物，年代比之前推估的800多萬年前還要早，這項發現令學者相當振奮。
澎湖縣文化局長曾慧香說，出土的古鱷魚化石在固化處理後，已經裝箱運往科博館重建，不過澎湖目前缺乏化石重建經費，將向中央爭取；化石出土地尚未公告為遺址保存，文化局已協調警方，每兩小時巡邏發現地，防止遺址遭到破壞。
