摘要

A new fossil record of a short-finned pilot whale, Globicephala macrorhynchus, from the Penghu Channel is described. The studied materials consist of a skull and a fused section of cervical vertebrae. The morphologic characters of the fossil specimens are closely similar to those of the modern species, Globicephala macrorhynchus, specimens of which were examined from the National Science Museum, Tokyo, Japan and compared to the fossil remains. The paper also includes a brief discussion of the faunal assemblage from the Penghu Channel in the Taiwan Strait.

短肢領航鯨(Globicephala macrorhynchus)是澎湖海溝動物化石群的新記錄種。本文描述該鯨頭骨化石及頸椎化石的形態特徵，並與東京國立科學博物館所藏之現生短肢領航鯨進行測量與比較，顯示化石種與現生種之頭骨形態非常相近。從該標本石化程度研判，應與澎湖海溝陸相動物群同屬更新世晚期。
