1. Pseudofurnishius (Conodonta) from the Triassic Drežnica section, Bosnia and HerzegovinaTea Kolar-Jurkovšek, Carlos Martínez Pérez, Hazim Hrvatović, Dunja Aljinović, Špela Goričan, Ferid Skopljak, Bogdan Jurkovšek, 2023, original scientific article Abstract: Triassic strata in the Drežnica section, Bosnia and Herzegovina have been examined biostratigraphically. The limestone and dolostone strata were deposited in deep pelagic environment. The conodont faunas are marked by prevailing elements of the genus Pseudofurnishius including clusters that enabled to distinguish the huddlei (lower Longobardian) and murcianus (upper Longobardian–?Cordevolian) Zones, the later fauna is characterized by the presence of Budurovignathus with rare representation of Gladigondolella and Paragondolella. This is the first report on recovery of Pseudofurnishius in the region.

2. Analysis of the geological control on the spatial distribution of potentially toxic concentrations of As and F- in groundwater on a Pan-European scaleElena Giménez-Forcada, Juan Antonio Luque-Espinar, María Teresa López-Bahut, Juan Grima-Olmedo, Jorge Jiménez-Sánchez, Carlos Ontiveros-Beltranena, José Angel Díaz-Muñoz, Daniel Elster, Ferid Skopljak, Denitza D. Voutchkova, Birgitte Hansen, Klaus Hinsby, Jörg Schullehner, Eline Malcuit, Laurence Gourcy, Teodóra Szőcs, Nóra Gál, Daði Þorbjörnsson, Katie Tedd, Dāvis Borozdins, Henry Debattista, Nina Rman, 2022, original scientific article Abstract: The distribution of the high concentrations of arsenic (As) and fluoride (F-) in groundwater on a Pan-European scale could be explained by the geological European context (lithology and structural faults). To test this hypothesis, seventeen countries and eighteen geological survey organizations (GSOs) have participated in the dataset. The methodology has used the HydroGeoToxicity (HGT) and the Baseline Concentration (BLC) index. The results prove that most of the waters considered in this study are in good conditions for drinking water consumption, in terms of As and/or F- content. A low proportion of the analysed samples present HGT≥ 1 levels (4% and 7% for As and F-, respectively). The spatial distribution of the highest As and/or F- concentrations (via BLC values) has been analysed using GIS tools. The highest values are identified associated with fissured hard rock outcrops (crystalline rocks) or Cenozoic sedimentary zones, where basement fractures seems to have an obvious control on the distribution of maximum concentrations of these elements in groundwaters.
