Its largest diameter is 6.4 mm long and it is radially symmetrical.

[2] Tateana has a central zone to where all the radial striations meet into the middle.

The fossil is Pound Quartzite, Upper Adelaide Superbasin series.

[2] Tateana was a deep sea, soft bodied organism,[4] that most likely fed on the bio-mat.
