*****************************************************************

Plants developed early in the fossils records. The first blue-green alga appears 3.4 billion years ago. Mounds of these single-celled plants ringed the Earth’s continents, becoming the dominate organism in the last half of the Precambrian. Over the millennia, the minerals trapped in the mats solidified into stone, which we call stromatolites. Blue-green alga masses still form stromatolites in such places as Shark Bay, Australia. |
