This is an extremely rare and enigmatic fossil. It is a beautiful Dickinsonia costata from the White Sea region of Russia. Dickinsonia is generally regarded as a member of the Vendazoa - a group of somewhat obscure animals that thrived just before most of the modern multicellular animal phyla appeared (Chengjiang, Burgess Shale, etc.). It is unclear if the Vendazoa are plants, animals, or something else entirely. It is thought by some possibly to be an annelid worm, or even a jellyfish, coral, sea anemone, an arthropod, a bacterium, a new phylum, or even a new kingdom. This specimen showcases the classic Dickinsonia features beautifully - ovoid with somewhat radial tubes emanating from a central ridge. The detail of this Dickinsonia is quite striking and simply amazing. The distinct fossil is well centered on a block of very fine-grained sandstone. This is a museum quality example of this strange, enigmatic Precambrian organism.
