Tappania plana

Tappania plana is a fungus appearing in the form of roughly spherical acritarchs, around 30 to 60 micrometers in diameter, with one or two small necks and small branched tubes emerging from the central body.

They first lived around 1630 million years ago, during the Calymmian, and went extinct 550 million years ago, during the Ediacaran.
