abstract = {Xiphosurids are aquatic chelicerates widely viewed as examples of so-called ‘living fossils’ due to their apparent morphological conservatism and limited diversity since at least the Jurassic. However, earlier representatives were much more diverse and morphologically disparate. Particularly striking are hypertrophied genal spines and reduced thoracetrons of the Triassic austrolimulids, possibly related to their colonization of brackish or freshwater habitats. Here we describe \textit{Polonolimulus zaleziankensis} gen. et sp. nov., a new austrolimulid genus from the Early Triassic of Holy Cross Mountains, Poland. Geometric morphometric analysis positions the new find among the morphologically most ‘extreme’ austrolimulids, extending the geographic range of those forms to Central Europe. A palaeobiogeographic reconstruction of Triassic xiphosurids reveals their surprisingly wide distribution already in Early Triassic, suggesting either an earlier dispersal in the Late Permian or a rapid diversification in the earliest Triassic. The reconstruction of most austrolimulid occurrences within or proximal to the shallow marine areas casts doubts on the hypothesis they inhabited fully freshwater palaeonvironments, which should be reinvestigated in the future. The new material further adds to the growing understanding of xiphosurid diversity and evolution in the early Mesozoic.},

abstract = {There is evidence that education levels have an impact on people's attitudes toward vaccination. The recent COVID-19 pandemic has highlighted the need to maximize vaccinations - one of the most efficient ways to prevent the spread of infectious diseases. Young individuals play a major role in disease transmission due to their intense social life and frequent asymptomatic infections. In this study, a survey of upper secondary school students in Poland was conducted to assess their microbiological awareness depending on subjects that they studied on the extended level and COVID-19 vaccination willingness. Participants learning biology and chemistry on the extended level had significantly higher microbiological awareness. Clear proof of microbiological awareness's influence on vaccination willingness was not found. Although studying biology did not significantly influence students' willingness to be vaccinated, their place of residence did. Students from bigger cities were more willing to get vaccinated. These results show that while science education raises microbiological awareness among upper secondary school students, place of residence, likely through social pressure, is a more important factor influencing vaccination willingness. It is suggested that more effort should be put into educating society as a whole and encouraging vaccination particularly.},
