Footnote
This specimen stands as evidence of some of the world’s earliest life forms. Stromatolites first appeared more than 3.5 billion years ago, forming in the shallow, warm waters of the Earth’s primordial seas. There, microbial mats trapped and bound fine sediment and minerals, creating layers over vast periods of time. The banding visible here preserves that gradual process, offering a direct link to life in its earliest stages.
