Saarina are cloudinimorph fossils from the Ediacaran (Vendian) and Early Cambrian marine deposits of European Russia and Laurentia. They are tubes made up of stacked conical elements. These fossils are comparable to the dwelling tubes of worms or cnidarians.
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).
S. kirsanovi fossils were found in a core from the Vorob'evo No.1 borehole, Moscow Region and in a core from the Malinovka borehole, near Obozersky in the Arkhangelsk Region.
S. juliae was found in a core from the Gavrilov-Yam No.5 borehole, Yaroslavl Region. The deposites with S. kirsanovi and S. juliae are referred to the Redkino Horizon, Upper Vendian (Ediacaran), and are about 558 mya old.
They are also known from early Cambrian rocks in the USA.[1]
