Here we delineate a diverse Entobia assemblage from Sicily, the first described from this Mediterranean island, based on the discovery of well-preserved natural casts. The studied association is represented by seven ichnotaxa, Entobia cateniformis, E. cateniformis form A, E. geometrica, E. laquea, E. ?megastoma, E. ovula, E. ?paradoxa, which come from the late Caenozoic sites of Altavilla Milicia and Sferracavallo, in north-western Sicily. Aragonitic bivalves, mostly veneroids, served as substrate for the boring organisms responsible of producing these ichnotaxa. Entobia was also found associated with natural casts of the boring Caulostrepsis taeniola, produced by polychaetes. Ichnology and shell-bed taphonomy indicates that investigated deposits formed in conditions of low rate of sedimentation; post depositional processes involved chemical conditions favorable to the preservation of calcite shells.}, year = {2022}, eissn = {2039-4942}, pages = {211-228}, orcid-numbers = {GARILLI, VITTORIO/0000-0001-8809-4176; DOMINICI, STEFANO/0000-0003-3719-0605} } @article{MTMT:32833540, title = {Nodulichnus hungaricus igen. et isp. nov. from the Early Miocene of North Hungary}, url = {https://m2.mtmt.hu/api/publication/32833540}, author = {Fodor, Rozália and Dávid, Árpád}, doi = {10.14241/asgp.2022.06}, journal-iso = {ANN SOC GEOL POL}, journal = {ANNALES SOCIETATIS GEOLOGORUM POLONIAE}, volume = {92}, unique-id = {32833540}, issn = {0208-9068}, year = {2022}, eissn = {0208-9068} } @{MTMT:33351198, title = {A rája lakomája-Piscichnus waitemata a bükki kora-miocénből}, url = {https://m2.mtmt.hu/api/publication/33351198}, author = {Dávid, Árpád and Fodor, Rozália}, booktitle = {24.

Calcareous Pliocene deposits from the Baia de Nossa Senhora section contain numerous, diverse, well-preserved natural casts of invertebrate borings. The study of this type of fossils adds to knowledge on the dispersal of benthic faunas across oceans to volcanic oceanic islands. The borings belong to seven ichnogenera and twenty-two ichnotaxa at the ichnospecies level with more than half pertaining to Entobia, which is produced by clionaid sponges. Other borings found were produced by bivalves (Gastrochaenolites), polychaete worms (Caulostrepsis and Maeandropolydora), sipunculid worms (Trypanites), phoronid worms (Talpina) and ctenostome bryozoans (Iramena). The occurrence, ichnogeny, distribution and preservational state of the borings suggest that the bearing bioclasts have been exposed for several years on the sea floor. The borings derive from different bathymetric zones on the shelf, and their formation took place during several bioerosional phases. The association of borings belongs to the Entobia ichnofacies, which is typical of carbonate rocky shores, and shows close similarity to those described from the Paratethys, Mediterranean and partly the eastern Atlantic regions. This fits the idea that most of the Neogene shallow-water marine fauna in the Azores is biogeographically related to the eastern Atlantic shores.}, keywords = {hard substrate; Bioerosion; trace fossils; Ichnology; Geosites}, year = {2021}, eissn = {1872-616X} } @{MTMT:31924735, title = {Adalékok a mecseki középső-miocén paleoichnológiájához (Hetvehely, vasúti bevágás)}, url = {https://m2.mtmt.hu/api/publication/31924735}, author = {Fodor, Rozália and Dávid, Árpád}, booktitle = {23.

Two main marine units are recognised, labelled CNM and ALT, separated by an angular unconformity and formed by elementary depositional sequences (CNM1-4, ALT1-5). The succession was subdivided by means of calcareous nannoplankton biostratigraphy into upper Pliocene (Piacenzian: CNM1-4 and ALT1-4) and lower Pleistocene (Gelasian, ALT4-5), covering the onset of the Quaternary glaciation. The main asset of the succession is driven by tectonic compression and accommodation by transpressional faults, a regime that led to a change in the direction of fluvial sediment delivery, from axial (mid-Piacenzian: CNM), to transverse with respect to the basin elongation (upper Piacenzian-Gelasian: ALT). High-frequency eustatic changes drove the formation of elementary depositional sequences, the building blocks of CNM and ALT. During the late Piacenzian, a phase of gradual passage from the mid-Piacenzian warm period to the Quaternary glaciation, bioclastic production was still high, characterising the maximum flooding intervals of the two composite depositional sequences CNM and ALT. Mixed carbonate-siliciclastic lithosomes of both CNM and ALT show a good correlation with shallow marine shell-rich detrital carbonates of Northern and Southern Italy and with Mediterranean deep-water sapropel clusters, suggesting common climatic forcing. Some tropical species thought to disappear from the Mediterranean at around 3.0 Ma, including Pecten bosniasckii, Macrochlamys latissima, Spondylus crassicosta, Lucina orbicularis, Isognomon maxillatus, Crassatina concentrica, Gastrana lacunosa, Callista italica, Circomphalus foliaceolamellosus and Persististrombus coronatus, are present in the upper Piacenzian of Sicily (top of the MN16a Zone and the MN16b/17 Zone of calcareous nannofossil biostratigraphy).
