Abstract: Skull remains of Balaenoptera edeni from the Holocene (about 8800 to 4000 years before present; a transgressive period) of Osaka City, Japan, was previously identified as B. acutorostrata. Here, we describe in detail and reidentify it based on having a large alisphenoid, which contacts with the squamosal widely and a broader rostrum than the one of B. acutorostrata. The specimen adds a chronologically and geographically new record to the not well-known species. The specimen suggests that the modern distribution of the species probably had already established about 8800 to 4000 years ago, which was the age of the Jomon transgression creating the Kawachi Bay, the former condition of Osaka Plain. More remains of B. edeni will provide better resolution of their distributional history.
