Fossil specimen of the stromatolite Chlorellopsis coloniata from the Green River Formation of Wyoming, 54–43 million years old (early Eocene).
This Cryptozoon type stromatolite was very likely to have been built by plant-like green or red, algae (Chlorophycophyta), as opposed to cyanobacteria (that are Eubacteria). It is hypothesized that red and green algae appeared some 800 million years ago having acquired chloroplasts from eukaryotes through endosymbiosis to carry out photosynthetic metabolism using sunlight for their energy needs.
Stromatolites are the oldest known fossils, dating back more than 3 billion years. Basically Stomatolites are prokaryotes (sort of an ancient cousin to algae) that thrived in warm aquatic environments and built reefs much the same way as coral does today. They are the oldest living organisms on the planet, and are believed to be the first living organisms on Earth.
The name Stromatolite comes from the Greek words that mean bed of rocks.
