Nemaia simplexDescription: This death assemblage of Vendian medusoids predates the Cambrian Explosion by tens of millions of years. Many early attempts at diversity existed at this time, both here and in the Ediacara Fauna of the Flinders Ranges of Australia. Many strange forms were present, some of which still do not have any parallels in modern times. These jellyfish-like examples are one that is relatively easy to attribute to descendants alive today. The incredible soft-bodied preservation is believed to be the result of impressions made in a microbial mat contained within the sand.
