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[4] in the lumen of the calcium-secreting glands in serpulids.

[5] Vinn has studied the evolution of symbiosis in several groups of early invertebrates such as cornulitids, microconchids, bryozoans, brachiopods, crinoids, stromatoporoids, tabulates and rugosans.

[2] A Late Devonian coral species ?Michelinia vinni is named in honour of his contribution to knowledge of ecology of Palaeozoic bioconstructing organisms.
