糸魚川淳二名古屋大学名誉教授は,1929年(昭和4年)8月21日に岐阜県恵那郡坂下町(現 中津川市坂下町)に生をうけ,2021年(令和3年)11月11日に永遠の眠りにつかれた.先生は,ご自身を「地質古生物学と博物館−二足の草鞋を履く」と評されていた.京都大学入学から大学教官時代は地質・古生物学の徒であり,1970年代以降は瑞浪市化石博物館の設立に深く関わったことから博物館研究に傾き始め,二足の草鞋を履くに至る.

A paleontological restoration of the early diverging pinniped, enaliarctine gen. et sp. undet., which was described and identified by Kohno et al. (2021), was presented as a 3D model. The form was reconstructed based on MFM18009 (complete skull, distal half of the left mandible, the atlas, distal half of the left humerus, proximal half of the left ulna, the third metacarpus, thoracic vertebrae and ribs) and restored by the last author’s scientific comments.

A pinniped fossil was found at the construction site of the Togari-Tsukiyoshi City Road in Akeyo-cho, Mizunami City, Gifu Prefecture, Japan in September 2020. We briefly report this new discovery of a partial skeletal bones belonging to a single individual (MFM18009), which was recovered from the lowermost part of the Yamanouchi Member of the Akeyo Formation, the Mizunami Group (lower Miocene: ca 18 Ma). MFM18009 is consisted from a complete skull, distal half of the left mandible, the atlas, distal half of the left humerus, proximal half of the left ulna, the third metacarpus, thoracic vertebrae and ribs. MFM18009 seems to belong in the Pteronarctos-Pacificotaria species complex of pinnipediforms, and is provisionally identified as Enaliarctine genus and species undetermined.

Additional strontium isotope ratio (87Sr/86Sr) of molluscs including Crenomytilus grayanus (Dunker), from the Akeyo Formation of the Mizunami Group in Mizunami City, Gifu Prefecture, central Japan are determined. The strontium isotopic ages suggest that the Crenomytilus grayanus-bearing horizon (most-lower part of the Yamanouchi Member, Akeyo Formation) has been deposited at ca. 17.8 Ma. In addition, upper part of the Kubohara Facies (middle part of the Maki Member), Iwamura Group has been deposited at same age of the Yamanouchi Member.

The type material of Linuparus canadensis (Whiteaves, 1885a) and Linuparus vancouverensis (Whiteaves, 1895) from British Columbia, Canada, are re-illustrated. Key features not originally mentioned are indicated. Many eastern North American occurrences previously referred to L. canadensis should be placed within L. keyesi Kornecki et al., 2017. Thus, the geographic range of L. canadensis is modified and restricted to Western and Central North America.
