Fun fact! Did you know... stromatolites are distinctive mounds that appear in shallow seas in the Bahamas, Australia, and elsewhere. As photosynthesizing bacteria thrive near the water’s surface, they form dense mats. Over time, the mats trap and bind sediments, which harden into layers of limestone that accumulate one by one to form the mounds. Today, stromatolites are rare. But this wasn’t always the case. Before the advent of animals that graze on mats, or of corals that compete with them for
