Abstract
A fossil gametophytic thallus, resembling Riccia L., from the Barail Sandstone (Early Oligocene) of the Thongjaorok Stream section (24°27′41″N and 93°44′40″E) of Manipur in Northeast India is reported as a new species — Riccia thongjaorokensis. Description of this new taxon is based on a cluster of 5–6 well preserved gametophytic thalli. This paper deals also with the paleoecology of the area.
