Calcimicrobial oncoid coatings from the Pliensbachian Massone Member (Calcari Grigi Formation, Trento Platform, Italy). Preliminary communication.

Oncoids built by calcimicrobial laminae from the Pliensbachian Massone Member (Calcari Grigi Formation, Trento Platform) have been studied in detail for the first time. Two groups of microorganisms attributed to calcified cyanobacteria have been identified.The first represents a new taxon of the family Thaumatoporellaceae De Castro; the second is provisionally assigned to Pseudolithocodium carpaticum Mi ik.
