Saarina are cloudinimorph fossils from the Ediacaran (Vendian) and Early Cambrian marine deposits of European Russia and Laurentia.

Fossils of the type species, S. tenera, were found in a core from the Gatchina No.13 borehole in the Leningrad Region, Russia.

The most conspicuous deposits associated with these fossils are referred to as the Lomonosov Fm., Lontova Horizon, and lower Tommotian (=Cambrian Stage 2).

The deposites with S. kirsanovi and S. juliae are referred to the Redkino Horizon, Upper Vendian (Ediacaran), and are about 558 mya old.

[1] Saarina was a tube-dwelling organism of unknown biological affinity, known from its siliciclastic deposits dating to the late Ediacaran (Vendian) and lowest Cambrian of the Russian Platform.
