Algae,  Vendian Period.

Detailed piece of algae.  Interesting pattern.

The Vendian Period spans about the last 110 million years of the Proterozoic Eon from about 540 to 650 million years ago.  It is during this time that macroscopic soft-bodied animals appeared.  Algae appeared at least one billion years ago.

By the end of the Vendian the supercontinent, Rodinia, which formed from the collisions of the major land masses approximately 1.2 billion years ago, had started to fragment into continents that would reconnect at the end of the Paleozoic Era over 300 million years later.
