“…A better understanding of fish fossils is needed to better understand the marine and continental fossil records. Through the study of fish fossils, we can reconstruct the ancient fishes and their related paleoenvironments, and infer the composition and origin of fishes in a specific period, which is of great significance to the study of marine fish paleobiogeography and reveal the evolution process of fishes [20].…”

Computed tomography (CT) is a widely used nondestructive testing (NDT) technique for material research, paleontology research and other fields. However, it is difficult for CT to reconstruct flat objects at high magnification ratios. Computed laminography (CL) enables high-resolution imaging for flat objects due to its unique scanning geometry. A challenging task for CL image reconstruction is to deal with the cross-section artifacts resulting from the incomplete projection data acquired from the CL scan. An effective multi-scale fusion reconstruction algorithm of CT and CL was proposed in this paper. The algorithm combining the advantages of the two scanning geometries, low-resolution CT data was used to compensate for the data missing in CL projection domain, and the cross-section artifacts were reduced. Experiments on paleontological fossils and multilayer printed circuit boards (PCB) were performed, where CT and CL data from different systems and scanning conditions. The results showed that the method can effectively suppress the cross-section artifacts of CL and obtain high-resolution reconstructed images.

“…The Surveys have and will continue to contribute to many scientific projects, and a list of scientific publications that describe the samples collected during the surveys can be found in the webpage. Many of the publications describe new species or report the discovery of species that had not been reported in Japan (Kakui and Kohtsuka, 2015;Kakui, 2015, 2019;Jimi and Fujiwara, 2016;Izumi et al, 2017;Jimi et al, 2017Jimi and Kajihara, 2018;Kajihara, 2019, 2021;Tanaka et al, 2019;Saito, 2020;Tsuyuki et al, 2021), while others are in the field of molecular phylogeny (Kushida and Reimer, 2019), embryology (Wakabayashi, 2017), behavior (Yoshikawa et al, 2018), evolution (Kakui and Hiruta, 2017), methods development (Maeno et al, 2019), and paleobiology (Mitsui et al, 2021). Information on animals obtained by the surveys are publicly available, from the webpage described above and through RINKAI (Regionally Integrated Marine Database; https://www.shimoda.tsukuba.ac.jp/~marinelife-db/), a database including organisms collected in these surveys.…”

“…Fossil records of these otoliths are known from the Devonian through the Mesozoic to Holocene worldwide (e.g., Nolf, 1985). Numerous paleontological studies have been conducted on fossil otoliths from Cenozoic deposits (e.g., Schwarzhans, 2003Schwarzhans, , 2012Girone and Nolf, 2009;Mitsui et al, 2021). Although Mesozoic otolith records are less abundant than Cenozoic records (e.g., Nolf, 1985;Schwarzhans, 2018), they offer a wealth of information, including biostratigraphic, paleobiogeographic, and paleoecological insights, as well as valuable details regarding the evolutionary history of fishes.…”

The Lower Cretaceous otolith assemblage from the Kimigahama Formation (Barremian) of the Choshi Group, Chiba Prefecture, Japan, is described. The Kimigahama Formation consists of bioturbated silty sandstone, sandy siltstone, and hummocky and swaley cross-stratified sandstone, representing an offshore to shoreface depositional environment. A total of five otolith types were identified, including undetermined Teleostei, Pterothrissinae, Elopiformes, Argentinidae, and Ichthyotringidae. Among them, Ichthyotringidae from Kimigahama Formation is the oldest Ichthyotringoidei. Based on the shallow marine setting of the Kimigahama Formation, the Barremian Pterothrissinae and Argentinidae in East Asia inhabited shallow marine environments, whereas the habitat of extant species is the deep sea. Furthermore, our new data on Pterothrissinae, Argentinidae, Ichthyotringoidei, and Elopiformes from Barremian strata in the northwestern Pacific indicate that these taxa exhibited a cosmopolitan distribution in the Pacific, Tethys, and Atlantic seas during the middle Early Cretaceous.
