Olev Vinn graduated in geology at the University of Tartu in 1993. Vinn holds an M.Sc. degree in paleontology and stratigraphy from the University of Tartu in 1995 and a Ph.D. degree in geology from the same university in 2001. From 2001 to 2007, Vinn worked as a Researcher, and a Senior Researcher at the Department of Geology, University of Tartu since 2007. Vinn is a Member of the Paleontological Association and the Paleontological Society. Vinn's main research interests are (1) tube ultrastructure and evolution of biomineralization in annelid tubeworms; (2) biological affinities, shell structure, and evolution of problematic tubicolous fossils; (3) bioerosion and biofouling, paleoecology and evolution; (4) evolution of symbiosis and predation.

Michał Zatoń earned his PhD in 2007 studying Middle Jurassic ammonites. In 2013 he received his habilitation degree (DSc) after research on selected problems of hard substrate biotas. Currently he is an associate professor on the Faculty of Earth Sciences, University of Silesia in Sosnowiec, Poland, where he is involved in both teaching and research. His main research is still focused on hard substrate biotas, mainly microconchid tubeworms, cyclostome bryozoans and mobile hard substrate paleoecology. His other research interests include taphonomy, predator-prey interactions and Devonian paleoenvironments during the times of biotic crises.

I was born in 1961, in Estonia. I studied geology in the University of Tartu and graduated in 1984. In the same year I started working in the Institute of Geology in Tallinn. For the past 15 years I have been working as the chief curator in the Department of Collections. I have contributed to creating the SARV Database for the geocollections of Estonia. I have also devoted a lot of time into teaching and the popularization of geology.
