R. Kozłowski (1974) reported
accumulations of organic vesicles from
Ordovician calcareous glacial bulders
found in Tertiary deposits in Poland. He
interpreted them as eggs of polychete
annelids (Polychaeta).
Kozłowski's material was reexamined
with TEM methods and reinterpreted as
presumably blue-green algae
(Cyanophyta) or Cyanobacteria.
Each specimen, about 1 mm in size,
represents irregular accumulation o fine
(15-30 micrometers) vesicles.
