However, the fossil record of the residual color patterns in freshwater bivalves could be traced only to the Miocene, greatly limiting color pattern evolution knowledge. We present the color patterns of the Cretaceous freshwater bivalves belonging to three extinct families of the order Trigoniida (hereinafter the Kitadani Freshwater Bivalves) from Japan, which is the oldest and the second fossil record of freshwater molluscan color patterns. The Kitadani Freshwater Bivalves consists of two types of color patterns: stripes along the growth lines and radial rays tapered toward the umbo, which resemble that of the colored bands of extant freshwater bivalves. This resemblance of the color patterns between the Kitadani Freshwater Bivalves and the extant species indicates that the color patterns of the freshwater bivalves represent the convergent evolution between Trigoniida and Unionida. To explain this convergent evolution, we advocate three conceivable factors: the phylogenetic constraints, monotonous habitats typical of freshwater ecosystems, and the predation pressure by visual predators in freshwater sediments.}, year = {2022}, eissn = {2045-2322} } @article{MTMT:31898690, title = {Complex food preference analysis of the Late Cretaceous (Santonian) lizards from Iharkút (Bakony Mountains, Hungary)}, url = {https://m2.mtmt.hu/api/publication/31898690}, author = {Gere, Kinga and Bodor, Emese Réka and Makádi, László and Ősi, Attila}, doi = {10.1080/08912963.2021.1887862}, journal-iso = {HIST BIOL}, journal = {HISTORICAL BIOLOGY}, volume = {33}, unique-id = {31898690}, issn = {0891-2963}, year = {2021}, eissn = {1029-2381}, pages = {3686-3702}, orcid-numbers = {Bodor, Emese Réka/0000-0003-3894-2506; Ősi, Attila/0000-0003-2967-997X} } @article{MTMT:32318256, title = {Xenodens calminechari gen. et sp. nov., a bizarre mosasaurid (Mosasauridae, Squamata) with shark-like cutting teeth from the upper Maastrichtian of Morocco, North Africa}, url = {https://m2.mtmt.hu/api/publication/32318256}, author = {Longrich, Nicholas R. and Bardet, Nathalie and Schulp, Anne S. and Jalil, Nour-Eddine}, doi = {10.1016/j.cretres.2021.104764}, journal-iso = {CRETACEOUS RES}, journal = {CRETACEOUS RESEARCH}, volume = {123}, unique-id = {32318256}, issn = {0195-6671}, abstract = {The mosasaurids (Mosasauridae) were a group of lizards that became highly specialized for marine life in the mid-Cretaceous. By the end of the Cretaceous, they had undergone an adaptive radiation, and showed a wide range of body sizes, locomotor styles, and diets. Their ranks included piscivores, apex predators, and durophages. Here, we report a new taxon, Xenodens calminechari gen. et sp. nov., from the upper Maastrichtian phosphates of Morocco, with dental specializations unlike those of any known reptile. Teeth form a unique dental battery in which short, laterally compressed and hooked teeth formed a saw-like blade. Unique features of tooth structure and implantation suggest affinities with the durophagous Carinodens. The tooth arrangement seen in Xenodens not only expands known disparity of mosasaurids, but is unique among Squamata, or even Tetrapoda. The specialized dentition implies a previously unknown feeding strategy, likely involving a cutting motion used to carve pieces out of large prey, or in scavenging. This novel dental specialization adds to the already considerable disparity and functional diversity of the late Maastrichtian mosasaurids and marine reptiles. This provides further evidence for a diverse marine fauna just prior to the K-Pg extinction.(c) 2021 Elsevier Ltd.

Detailed investigation of the assemblage by multiple visualization techniques (scanning electron microscopy, polarizing light microscopy, X-ray micro-computed tomography), quantitative morphometric analyses, and micro X-ray fluorescence spectrometry revealed a diverse composition of five different eggshell morphotypes (MT I-MT V) and three subcategories within the second morphotype (MT II/a, b, c), with MT I being by far the most abundant (83%) in the assemblage. MT I, MT III, and MT V represent theropod dinosaurian eggshells, whereas MT II and MT IV show characteristics of crocodilian and squamate eggshells, respectively. Hence, despite their fragmentary nature, these eggshells represent the first clear evidence that various sauropsid taxa had nesting sites near the ancient fluvial system of Iharkút. Besides the implied taxonomic diversity, two unique features add to the significance of this eggshell assemblage. First, it contains the thinnest rigid crocodilian (MT II/c) and squamate (MT IV) eggshells ever reported. Moreover, one of the identified theropod morphotypes, MT I, is also among the thinnest fossil dinosaurian eggshells, the thinness of which is only rivalled by the eggshells of the smallest Mesozoic avian eggs known to date. Second, the Iharkút eggshell assemblage consists exclusively of thin eggshells (≤300 μm), a condition unknown from any other fossil eggshell assemblages described to date. Combined with the knowledge acquired from skeletal remains, these peculiarities give additional insights into the paleoecology of the terrestrial sauropsid fauna once inhabiting the ancient island of Iharkút. Finally, the presence of well-preserved eggshells recovered from two different sites representing different depositional environments provides further evidence for previous taphonomic and sedimentological conclusions, and also expands our knowledge of the special conditions that allowed the preservation of these delicate eggshell fragments. © 2017 The Author(s).}, year = {2017}, eissn = {1789-3348}, pages = {73-133}, orcid-numbers = {Botfalvai, Gábor/0000-0002-5479-9036; Szentesi, Zoltán/0000-0002-7019-5478; Ősi, Attila/0000-0003-2967-997X} } @article{MTMT:2986714, title = {Facies architecture and palaeoenvironmental implications of the upper Cretaceous (Santonian) Csehbánya formation at the Iharkút vertebrate locality (Bakony Mountains, Northwestern Hungary)}, url = {https://m2.mtmt.hu/api/publication/2986714}, author = {Botfalvai, Gábor and Haas, János and Bodor, Emese Réka and Mindszenty, Andrea and Ősi, Attila}, doi = {10.1016/j.palaeo.2015.10.018}, journal-iso = {PALAEOGEOGR PALAEOCL}, journal = {PALAEOGEOGRAPHY PALAEOCLIMATOLOGY PALAEOECOLOGY}, volume = {441}, unique-id = {2986714}, issn = {0031-0182}, year = {2016}, eissn = {1872-616X}, pages = {659-678}, orcid-numbers = {Botfalvai, Gábor/0000-0002-5479-9036; Haas, János/0000-0003-0929-8889; Bodor, Emese Réka/0000-0003-3894-2506; Mindszenty, Andrea/0000-0001-8927-3053; Ősi, Attila/0000-0003-2967-997X} }
