Please, don’t hesitate to contact me if you have any comments on my blog or my research, questions, offer of collaboration, or you simply want to say “hello”. 🙂
I live in Poland. I’m currently employed at the Institute of Paleobiology, Polish Academy of Sciences, as a fossil preparator. I’m interested in paleobiology and particularly in paleoecology and evolutionary physiology. Most of my research focuses on coprolites (i.e. fossil feces) and other trace fossils that represent food items that have entered the gastrointestinal tract, such as gut contents and regurgitalites:
– as a source of paleoecologic information, including diet (predator—prey interactions, carrion feeding, herbivory) and other life habits of animals [1,2,3,5,6,8], paleoenvironmental reconstruction [e.g. 2,4,5,6], and other ecologic relationships like parasitism and coprophagy [3,8]
– as a source of information about the digestive physiology of extinct animals [2,3,6] and their thermal physiologic evolution [e.g. 3]
– taphonomy and fossilization of feces [1,2,3,4,5,6,8], identification of coprolites [e.g. 1,2,5,6] and their utility in geology [e.g. 1,2,4,8]
I also make research on stromatolites  and microorganisms [3,7] exploring their significance for our understanding of ancient ecosystems.
I have worked on fossil material from the Permian [3,4,6,8], Triassic [2,4,5,7], and Cretaceous  of Poland [1,2,7], Russia [3,4,8], Australia , Uruguay , and Brazil .
