Some of the first forms of life on Earth are recorded in stromatolites present in rocks 3.5 billion years old. Although stromatolites continue to form in certain areas of the world today, they grow in greatest abundance in Shark Bay in western Australia. “On Mars, we’d expect stromatolites, even as old as 3.5-3.8 billion years, to be better preserved than on Earth as Mars hasn’t experienced geological processes like plate tectonics,” he said. The The fossil record of stromatolites is astonishingly extensive, spanning some four billion years of geological history with the forming organisms possibly having occupied every conceivable environment that ever existed on earth. Stromatolites are the oldest fossils on earth, dating back to more than three billion years ago. They were the dominant life form on earth for over 2 billion years and are thought to be primarily responsible for the oxygenation of the atmosphere.

Over time, organisms developed that grazed on stromatolites, and by the Cambrian Period, they numbered only 20% of their peak. Scientists had long known about stromatolites from the fossil record, but were surprised and delighted to find them still in existence when they were discovered in 1956 at Shark Bay, Western Australia. Systematics of the stromatolites has helped in ascertaining the age of vast sequences of the Proterozoic Eon (2500-542 Ma). In absence of the availability of the precise radiometric age of different strata of any Proterozoic succession, these are still used to determine the age of encompassing sequences. marine stromatolites display only a subset of the shapes and sizes of stromatolites in the rock Age (Ga) c b d 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 Column diameter (cm A few stromatolites are stilling forming today.

They saw a couple of nankeen night herons perched on a dead tree – were able to get the boat surprisingly close to them. Website Repair. stromatolites age.

The real significance of stromatolites is that they are the earliest fossil evidence of life on Earth. The oldest known stromatolites have been dated between 3,710 million years and 3,695 million years old, and were discovered from an exposed outcrop of metacarbonate rocks in the Isua supracrustal belt (ISB) in Southwest Greenland. Stromatolites are important because they are believed to be the evidence of early life.
