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....

| description | 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. In life, the shark is estimated to have been approximately less than 2 m in length. This is the second reported fossil record of C. hastalis in the Korean Peninsula and the first permineralized fossil remain as well. Although largely undescribed, fossil shark assemblage of the Duho Formation is similar to those of contemporaneous Japanese marine sediments, indicating epipelagic or pelagic sharks were already diversified throughout the East sea during the middle Miocene. |
