“…2), suggests that the specimen underwent significant decomposition underwater. The first steps of decomposition of a fish involve the disarticulation of the jaw and external scales as soft tissues (muscles, skins) decompose (Burrow and Turner, 2012). However, body parts are often disarticulated but still loosely connected (Burrow and Turner, 2012).…”

At this stage, invertebrate and vertebrate scavengers completely disconnect the bones by feeding on the soft tissue or the bones themselves (Burrow and Turner, 2012). In GNUE322001, the absent anal pterygiophores would have been disconnected and/or consumed by marine scavengers, indicating that the vertebrae have been underwater for a long time.…”

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.

The porolepiform sarcopterygian Holoptychius Agassiz, 1839 from the Upper Devonian is one of the most widely found vertebrates in the Palaeozoic fossil record. Holoptychius is considered to display a more ubiquitous mode of life and a greater potential of dispersion than any other sarcopterygian taxon, consistent with its cosmopolitan distribution and profuse fossil record, mainly represented by scales. Previous histological studies on the squamation of Holoptychius have discussed the variable ornamentation of the superficial layer, however the basal plate has been less explored. Here we furnish new histological data on the scales of Holoptychius, focusing on the mineralization rate and organization of the lamellar bone. Ground sections show that the basal plate is made of a stacking of thick collagenous layers with a plywood-like structure. Collagenous fibres are parallel within layers, with two successive layers orthogonally arranged and with every second layer rotated by an angle of 36º. This condition, known as a double-twisted plywood-like organization, is similar to that of other sarcopterygians like Eusthenopteron and extant coelacanths and dipnoans. The new palaeohistological data provide insights into the morphofunctional, palaeoecological and phylogenetical implications of the microstructural characteristics of the scales, adding to our knowledge of the histological diversity of osteichthyans.
