Citation: Chrysophyte cysts
taxonomic rank: order
Taxonomic discussion: An important characteristic used to identify members of the class Chrysophyceae is the presence of a siliceous cyst that is formed endogenously. Called statospore, stomatocyst or statocyst, this structure is usually globose and contains a single pore. The surface of mature cysts may be ornamented with different structural elements and are useful to distinguish species. [Wikipedia - Golden Algae page]

This is Archaeomonas cysts (Chrysophyceae), known from Miocene sediments of Paratethys (Hajos M., 1968).
