Collective motion by animal groups can emerge from simple rules that govern each individual's interactions with its neighbours. Studies of extant species have shown how such rules yield coordinated group behaviour, but little is known of their evolutionary origins or whether extinct group-living organisms used similar rules. Here, we report evidence consistent with coordinated collective motion in a fossilized group of the extinct fish Erismatopterus levatus, and we infer possible behavioural rules that underlie it. We found traces of two rules for social interaction similar to those used by extant fishes: repulsion from close individuals and attraction towards neighbours at a distance. Moreover, the fossilized fish showed group-level structures in the form of oblong shape and high polarization, both of which we successfully reproduced in simulations incorporating the inferred behavioural rules. Although it remains unclear how the fish shoal's structure was preserved in the fossil, these findings suggest that fishes have been forming shoals by combining sets of simple behavioural rules since at least the Eocene. Our study highlights the possibility of exploring the social communication of extinct animals, which has been thought to leave no fossil record.

Quaternary freshwater fish fossils are significant to consider the biogeographical history and evolution of Recent and Neogene freshwater fishes. In the present study, previous studies of Quaternary freshwater fish fossils from Japan are reviewed with the updated geological datum of each fossil bed.In Japan, Pleistocene sediments (e.g. Kobiwako Group) have yielded many pharyngeal teeth of cyprinids as well as spines and bones of siluriformes, which contribute to paleobiogeographical and histological studies of these taxa, although the fossils are fragments. Fish fossils from the Miyajima Formation of Tochigi and the Nogami Formation of Oita could possibly be utilized to calibrate molecular clocks of molecular phylogenetics, because these can be identified at the species level based on the articulated and well-preserved fossil specimens.Studies of fish bones and scales from shell mound remains of the Jomon period revealed the existence of extinct cyprinid groups of present Japan and regional extinction during the Holocene time in Japan. These studies are important to discuss the relationships between the transition of fish fauna and human activities.

The Plio-Pleistocene Kazusa Group, situated in the middle and upper basin of the Tama River in Northwestern Tokyo, Japan is known to have yielded various vertebrates, including both terrestrial and marine mammals as well as chondrichthyan fishes. Recently, osteichthyan fish fossils have been discovered from this stratum. Notably, marine fish fossils have been discovered in the Oyabe, Hirayama, Komiya, Oyamada, and Renkoji formations of Kazusa Group. Of these formations, the Oyabe Formation has revealed Clupeiformes and the first East Asian fossils of the Plotosidae, while the Renkoji Formation has yielded Clupeiformes, Clupeidae, Engraulidae, and the second recorded occurrence of the Mugilidae in Japan. These recent discoveries suggest that the Kazusa Group in Northwestern Tokyo has the potential to be a significant stratum for the study of Quaternary marine fossil osteichthyan fishes.

Sauropod teeth from the Tamagawa Formation of Kuji Group, northeastern Japan, were described and diet of the Kuji sauropod was inferred by dental microwear texture analysis (DMTA). The morphology and slenderness index (SI) of Kuji sauropod teeth indicate they belong to a titanosauriform somphospondyli sauropod and thus confirm the existence of a titanosauriform sauropod at the coastal area of East Asia during the late Turonian. Dental microwear texture (DMT) of the Kuji sauropod is compared with extant lepidosaurs with known dietary preferences, indicating a higher degree of oral food processing in the Kuji sauropod than in extant lepidosaurs. The Kuji sauropod fed on materials less resistant and softer than molluscan shells or exoskeletons of insects and likely relied on plant materials. Considering what is known about the paleoflora of the Tamagawa Formation, the most likely diet was ferns and gymnosperms. These initial results encourage future applications of DMTA to various sauropods, which could help to reveal the evolution of their feeding ecology and whether the increase of SI is associated with dietary change.

The osteological description and illustrations of the cyprinid fish Zacco platypus (Temminck and Schlegel, 1846) from Oita Prefecture, Japan are provided for studies on fossil cyprinid fishes found in East Asia and Japan. As a result of this study, it was found that the parietal, supraobital, dentary, opercle and urohyal of Z. platypus differ from those of Nipponocypris sieboldii and N. temminckii, which were considered as a member of the genus Zacco.
