|This is a remarkable nice and interesting plate with servile different fossils from the Vendian Ediacara Biota of the White Sea. There are two nice and detailed specimens of Dickinsonia minima on this piece. The larger Dickinsonia measures about 18 mm, the second is about 13 mm long. |
There is also a other Ediacara fossil of the rare offered species Palaeopascichnus delicates.
The genus Palaeopascichnus was initialy discriped as a meandering sediment feeder trace fossil.
Also the similarity a trilobite like track or other Cruziana or Diplichnites like Ichnofossils was discussed.
Today Palaeopascichnus is mostly interpretated as a body fossil like Charniodiscus oder Dickinsonia.
(See also Grazhdankin, 2014)
This plate contains also are some so called Wrinkle structures or Kinneyia like structures.
These are interpreted as microbial mats that have been slightly buried under sediment causing these ripple structures. Microbial mats have been also referred as “Elephant skin” by Seilacher et al in 2003. Presumably these microbial mats were grazing ground for Kimberella or Dickinsonia, Yorgia or other Ediacarian Biota.
Se we have here a very interesting and displayable piece that show a part of the Ediacaran biota community.
