Fossilized stromatolites ________.
A) formed around deep-sea vents
B) resemble structures formed by bacterial communities that are found today in some shallow marine bays
C) provide evidence that plants moved onto land in the company of fungi around 500 million years ago
D) contain the first undisputed fossils of eukaryotes

Question

Quizplus · Accepted Answer

Stromatolites are layered structures formed by the mineralization of bacterial communities, particularly cyanobacteria. These communities are found today in shallow marine environments, such as bays, where they continue to form similar structures. This resemblance helps scientists understand the conditions under which ancient stromatolites formed and the role of microbial life in Earth's history.
