Acritarchs are highly diversified polyphyletic group of marine organisms that have no clear biological affiliation. Spheroidal vesicles approx. 20 μm in diameter having a rigid smooth wall and frequently arranged in clusters (~2-100 specimens) connected by an external coating are proposed as a new taxon named Involusphaeridium gutschicki gen. et sp. nov. The article appeared in the Review of Palaeobotnay and Palynology, describes the acritarch morphology as well as the paleoenvironment in which these microorganisms were deposited; moreover organizes the systematic position of these organic remains.
