Scientists have calculated the Earth to be 4.54 billion years old, with an uncertainty of 50 million years on either side.
Here the extraction technique for meteorites is applied to a 2.1 Gya fossil stromatolite to reveal the presence of hemoglycin by mass spectrometry. Intact ooids from a recent (3000 Ya) stromatolite ...
Stromatolites are sedimentary formations, fossil evidence of the earliest colony organisms. Before they learned to make colonies, even their loner ancestors left a subtle mark: a thin rime of ...
Detailed studies yielded extensive cyanobacterial fossils. He said that these stromatolites were first discovered by J B Auden of the Geological Survey of India in 1933. “The discovery of ...
However, some live together in very large groups of cells that can accumulate minerals and leave behind quite large fossils. For example, cyanobacteria formed large structures called stromatolites in ...
