“…It is recognized that mesopelagic or other deep-water bony fi shes occupy signifi cant portions in diet of modern representatives of Mitsukurina and Dalatias (e. g., Duff y, 1997; Ergüden et al, 2017). Various bony fi sh fossils including Pleuronichthys, Vinciguerria and Zaprora previously were reported from the Duho Formation and these are assumed to be mesopelagic or benthic fi shes (Ko and Nam, 2016;Nam and Nazarkin, 2018;Nam et al, 2019). Th erefore, it is reasonable to assume that Mitsukurina cf.…”

First Deep-Sea Shark Fossil Teeth from the Miocene of South Korea

Important vertebrate fossil remains were collected in the Pohang Basin in South Korea for many decades, but only few have been described up to now. Here, three deep-sea shark teeth are described, which most likely derived from the Duho Formation (middle Miocene) near Pohang City, South Korea. One of the teeth is identified as belonging to the genus Mitsukurina, while the others are assignable to Dalatias. None of these taxa were previously reported from the Korean Peninsula. The occurrences of these deep-water fishes in the Pohang Basin support the hypotheses that the Duho Formation was deposited in a deep-sea environment, and sharks, even including benthopelagic forms were already widely distributed throughout the East Sea when this sea was still developing.

“…Th e East Sea started to form in the early Miocene by separation of the northern and southern Japanese archipelagos (e. g., Ko and Nam, 2016). Th e Duho Formation was deposited during the early stages of development and expansion of the East Sea in the middle Miocene (Pavlyutkin et al, 2016;Yun, 2020).…”

“…A pale grey to light brown homogeneous mudstone with intercalated sandstone is the main deposit of the Duho 4 Formation (Hwang et al, 1995;Kim and Paik, 2013). The Duho Formation produces a variety of marine invertebrate and vertebrate fossils, including mollusks (Kim and Lee, 2011;Kong and Lee, 2012), fishes (Ko, 2016;Ko and Nam, 2016;Kim et al, 2018;Nam et al, 2021;Malyshkina et al, 2022), and whales (Lim, 2005;Lee et al, 2012). Such a diverse fossil record has produced equally diverse paleoenvironmental interpretations during the deposition of the Duho Formation.…”

The partially articulated caudal vertebrae of a tuna were discovered from the Duho Formation (middle Miocene) of South Korea. This specimen was assigned to the genusAuxisand represents the second record of fossilAuxisfound in South Korea. We compared the vertebral morphology of the studied specimen to that of currently known species ofAuxis, including extinct taxa, but the specimen is not assigned to a new or existing species ofAuxisdue to poor preservation and a lack of diagnostic features. The discovery of a new specimen ofAuxissupports theories of high marine biodiversity in the East Sea (Sea of Japan) and the opening of the East Sea in the early to middle Miocene. A widely opened East Sea might have increased the abundance and diversity of large oceanic fishes such as tunas during the deposition of the Duho Formation. A taphonomic scenario of the specimen was inferred based on the lack of anal pterygiophores and the leaf imprint on the matrix. The specimen would have been exposed for at least a month in a low-energy sedimentary environment at the deep-sea bottom and undergone disintegration before being buried.
