Please, don’t hesitate to contact me if you have any comments on my blog or my research, questions, offer of collaboration, or you just want to say “hello”… ­čÖé

I’m from Poland and I’ve published my papers as an independent researcher. Since June 2017, I’m employed at the Institute of Paleobiology, Polish Academy of Sciences, as a fossil preparator. I’m widely interested in paleobiology and I focus primarily on fossil feces (coprolites) and other trace fossils that represent food items that have entered the gastrointestinal tract (bromalites), such as gut contents and regurgitalites:

ÔÇô as a source of paleoecologic information, including diet and other life habits of animals [1,2,3,5,6,8], paleoenvironmental reconstruction [e.g. 2,4,5,6], and various ecologic relationships as parasitism, coprophagy, etc. [3,8]

ÔÇô as a source of information about the digestive physiology of extinct animals [2,3,6] and their thermal physiologic evolution [e.g. 3]

ÔÇô 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’ve also done some research on stromatolites [7] and microorganisms [3,7].

I’ve worked on material from the Permian [3,4,6,8], Triassic [2,4,5,7], and Cretaceous [1]┬áof Poland [1,2,7], Russia [3,4,8], Australia [5], Uruguay [6], and Brazil [6].
