New example of Cosmopolitodus hastalis (Lamniformes, Lamnidae) from the Miocene of South Korea
The discovery of an isolated juvenile tooth of an extinct lamnid shark Cosmopolitodus hastalis (Agassiz, 1843) from the Duho Formation (middle Miocene), Pohang City, South Korea. This tooth is approximately 11 mm in crown height, suggesting a juvenile affinity of an individual this tooth originated....
