CHITINOZOANS

CHITINOZOANS: Extinct marine microfossils of uncertain affinity generally shaped like flasks, 50 - 2000 µm. Occurring individually or in chains, with varous sculpturing and basal appendages. Stratigraphic range from uppermost Cambrian to Devonian (ca. 510 - 300 Ma). Usually assumed to be animal remains, perhaps eggs. Eisenack (1931) presumped their wall was chitinous, which has never been demonstrated.
