Grzegorz Niedzwiedzki is a Researcher at Uppsala University's Department of Organismal Biology, specializing in vertebrate palaeontology and early tetrapod evolution. He holds a PhD from the University of Warsaw (2013) and has conducted expeditions across Poland, Russia, Tunisia, Greenland, and Sweden. His research focuses on Triassic-Jurassic vertebrate ecosystems, coprolite analysis, and early dinosaur evolution. Education: PhD in Biology (2013), University of Warsaw Master's in Biology (2007), University of Warsaw Bachelor's in Biology (2004), University of Warsaw Research Interests: Grzegorz's work analyzes fossilized footprints, coprolites, and skeletal remains to reconstruct ancient ecosystems. He has pioneered studies on Early Triassic predator ecosystems via coprolites and contributed to understanding dinosaur dietary habits through coprolite microbiota analysis. His fieldwork has uncovered critical fossils like the archosaur Smok wawelski and Early Jurassic dinosaur tracks. Key Achievements: Recipient of multiple prestigious awards (National Geographic grants, Prime Minister's Special Award) Over 100 peer-reviewed publications in journals like Nature , Palaeogeography, Palaeoclimatology, Palaeoecology , and Acta Palaeontologica Polonica Co-discoverer of the oldest known mammaliaform fossil in Greenland Grants & Collaborations: Multiple international expeditions funded by Polish and Swedish institutions Collaborations with the American Museum of Natural History and Uppsala University Labs/Teams: Affiliated with Uppsala University's Evolution and Development research group and collaborates globally on fossil expeditions and synchrotron imaging projects.

Lars Holmer is a Professor in Historical Geology and Palaeontology at Uppsala University's Department of Earth Sciences, specializing in Palaeobiology. He also serves as Director at Campus Management Organisation for Campus Lagerträdet. With an extensive publication record spanning decades, his research primarily focuses on brachiopods and early animal evolution during the Cambrian period and beyond. Professor Holmer's research centers on resolving the origin and earliest phylogeny of brachiopods and other lophophorates through detailed paleobiological investigation of their oldest fossil remains. His work combines traditional paleontological methods with molecular and morphological studies of living forms to understand evolutionary patterns across geological time. His research has particularly focused on Cambrian brachiopods, their morphology, phylogeny, and ecological adaptations throughout Earth's history. His publication record reveals a consistent focus on brachiopod evolution across multiple geological periods, with particular emphasis on Cambrian and Ordovician specimens. Holmer's work spans multiple continents including Sweden, China, Antarctica, Australia, and North America, demonstrating extensive international collaboration. His research frequently examines exceptional fossil preservation sites (Lagerstätten) that provide crucial insights into early animal evolution and biomineralization processes. As Director of Campus Management Organisation for Campus Lagerträdet, Professor Holmer also contributes to the administrative leadership of Uppsala University's campus facilities, balancing academic research with institutional responsibilities.
