Biology:Barskovia
From HandWiki
Barskovia is a torted conical shell known from earliest Cambrian small skeletal fossils, interpreted as a helcionelloid.
It has been found fossilized in the Platonovskaya Formation in Siberia. Due to its position in a deep layer of this rock formation, Barskovia is estimated to have occurred 541 million years ago at earliest.[1]
