The well preserved fossilized oogonia and 'Stems' of Charophytes, a specialised and advanced group of green algae, have been studied from the Late Quaternary sediments of Calcutta and identified as Chara fragilis related to fossils of C. globularis in its morphological features. It is mostly restricted to fresh water. It tends to disappear in marine environment.
