Abstract

Abstract. The generic name of the humpback whale, Megaptera was named after their forelimb, which means a “large wing”. New whale remains (specimen number: OMNH-QV 60) including the right scapula, humerus, and radius from the Namba Formation, Holocene in Osaka, Japan is reported as a humpback whale, Megaptera novaeangliae based on diagnoses of the species; having reduced acromion and coracoid processes of the scapula, and long humerus and radius. The body length of the individual can be estimated as 13 m based on the proportion between forelimb elements and body length. It suggests that OMNH-QV 60 is adult. The specimen is a certain record of Megaptera novaeangliae from Holocene sediments in Japan with size estimation.
日本大阪全新世(第四纪)的新座头鲸遗骸
摘要座头鲸的通用名称Megaptera是以它们的前肢命名的,意思是“大翅膀”。日本大阪全新世难波组的新鲸鱼遗骸(标本编号:OMNH-QV 60),包括右肩胛骨、肱骨和桡骨,根据该物种的诊断,被报道为座头鲸,Megaptera novaeangliae;肩胛骨的肩峰和喙突缩小,肱骨和桡骨较长。根据前肢元素和体长之间的比例,个体的体长可以估计为13米。提示OMNH-QV 60为成年人。该标本是日本全新世沉积物中新翅目昆虫的一个特定记录。
