Olev Vinn

Vinn graduated from the biology class of Tallinn 3. Secondary School in 1989. He studied geology at the University of Tartu from 1989 to 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. He is a senior research fellow in paleontology at the University of Tartu since 2007. He has published more than 250 peer-reviewed papers in international scientific journals. Since 2021, he has been an editor of the Journal of Paleontology. From 2025 onward, he has served on the editorial board of the leading geological journal Geology. In addition, he serves on the editorial boards of several other scientific journals in paleontology, biology, and geology indexed in Web of Science . ==Taxonomic studies==

Vinn has described new genera and species of brachiopods, cornulitids, microconchids, serpulid polychaetes and trace fossils. He is a specialist of extinct tubicolous fossils. A microconchid species Microconchus vinni is named in honour of his taxonomic studies of tentaculitoid tubeworms. ==Biomineralization studies==

Vinn has described the majority of the annelid skeletal ultrastructures. Oriented tube structures are present in many serpulid species and cannot be explained by the standard carbonate slurry model. Vinn and his co-authors have hypothesized that oriented structures in serpulid tubes have been secreted in the same way as in mollusc shells, based on their ultrastructural similarity. Vinn and his co-authors proposed alternative ways to explain the calcified secretory granules described by Neff in the lumen of the calcium-secreting glands in serpulids. They proposed that worm actually produces calcium-saturated mucus in the glands. The mucus is then deposited on the tube aperture, where crystallization of the structure is controlled by an organic matrix, as in molluscs. The calcified granules in the glands may only be an artifact of fixation and formed after the death of the worm. ==Paleoecology studies==

Vinn has studied the evolution of symbiosis in several groups of early invertebrates such as cornulitids, microconchids, bryozoans, brachiopods, crinoids, stromatoporoids, tabulates and rugosans. He has described serpulid faunas of Mesozoic to Recent hydrocarbon seeps. A crinoid species name Hiiumaacrinus vinni recognizes his significant contributions to the Silurian paleontology of Estonia. == Selected publications ==
