Zoltán Barkaszi is a researcher at the Department of Palaeontology of the National Museum of Natural History, National Academy of Sciences of Ukraine. He graduated from the Uzhhorod National University (Ukraine) and majored in zoology (2015). He was awarded a Ph.D. (2021) in zoology by the Schmalhausen Institute of Zoology, NAS of Ukraine. In the focus of his thesis were muroid rodents of the Ukrainian Carpathians, particularly their cranial and dental morphology, patterns of distribution, habitat preferences, and species diversity. His current research interests include the systematics, morphology, paleobiology, paleoecology, paleobiogeography, and phylogeny of various groups of terrestrial and marine vertebrates, mainly mammals and chondrichthyans.

Anastasiia Dubikovska is a bachelor in Biology and now she is a first-year student of master’s degree. During gaining a bachelor’s degree she studied insects (mostly caddisflies) of Mykhailivska Tsilyna Natural Reserve. Anastasiia also started the study of the fauna of Trichoptera of Getmansky National Nature Park, but now she focused on the study of Paleogene fishes. Anastasiia is interested in different fields of biological research, especially those accompanied with expeditions and trips (e.g. zoology, entomology, ecology, paleontology). On her free time, she likes to make and listen to music, drawing traditional and digital arts and watching the gameplays on YouTube.
