'''''Tappania''''' is an acanthomorph [[Biology:Acritarch|acritarch]] found in late [[Earth:Paleoproterozoic|Paleoproterozoic]], [[Earth:Mesoproterozoic|Mesoproterozoic]] and [[Earth:Neoproterozoic|Neoproterozoic]] rocks. The oldest examples are around 1630 million years old, making them the oldest known evidence of Eukaryotes in the fossil record.<ref>{{Cite journal|last=Butterfield|first=Nicholas J.|date=2015|title=Early evolution of the Eukaryota|journal=Palaeontology|language=en|volume=58|issue=1|pages=5–17|doi=10.1111/pala.12139|issn=1475-4983|doi-access=free}}</ref>
* ''Tappania plana'' appears in Paleoproterozoic formations of India (Deonar) and northern China (Baicaoping and Beidajian), both with an age of 1,630 mya. It is a roughly spherical acritarch, 30-60 μm in diameter, with one or two small necks. Small branched and / or partitioned tubes emerge from the central body.
* ''Tappania'' sp. It appears in deposits of the [[Earth:Neoproterozoic|Neoproterozoic]] in northern Australia, northwestern US and central Siberia, with an age of up to 850 mya and 200-300 mya stratigraphic presence. It is larger than ''Flat Tappania,'' up to 300 μm in length, with an elongated or lobed central body from where hyphae-like tubular extensions radiate.  These hyphae form a three-dimensional network around the central body.
