Jana Bruthansová is a paleontologist at the National Museum in Prague, where she is the curator of the Paleozoic invertebrate fossil collections. She has worked mainly on the paleobiology and taphonomy of Middle and Upper Ordovician invertebrates and trilobites. After a long maternity leave she returned back to these topics and is currently focusing on the paleobiology and systematics of Ordovician Bohemian conulariids.

Jana Schweigstillová is a researcher at the Institute of Rock Structure and Mechanics of the ASCR, v.v.i. (IRSM).
Her main interests are geochemistry and mineralogy of sediments, weathering and geomorphology of sandstones, salt crystallization or the experiments in the climatic test chamber (CTC 256, Memmert). For more than 10 years she has been interested in the scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDS) on the microscope Quanta 450 (FEI).

Heyo Van Iten is Professor of Geology at Hanover College in Hanover, Indiana USA. He is also a research associate of the Cincinnati Musem Center in Ohio USA. Since 1980 he has been conducting independent and collaborative research on the paleobiology and evolution of conulariids, Sphenothallus, and conulariid-like small shelly fossils. His current research includes a revision of the systematics and taxonomy of conulariids.
