Stromatolites are layered, biochemical, accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), through the action of certain microbial lifeforms, especially cyanobacteria. [12]

2024年3月10日 · Stromatolites are layered accretions of microorganisms, primarily cyanobacteria, mixed with sedimentary grains. These formations often occur in shallow water environments. They are one of the earliest forms of life on Earth that existed …

Stromatolite, layered deposit, mainly of limestone, formed by the growth of blue-green algae (primitive one-celled organisms). These structures are usually characterized by thin, alternating light and dark layers that may be flat, hummocky, or …

2021年1月18日 · Stromatolites are living fossils and the oldest living lifeforms on our planet. The name derives from the Greek, stroma, meaning “mattress”, and lithos, meaning “rock”. Stromatolite literally...

2025年2月6日 · What are Stromatolites? A new educational video provides insight into stromatolites on Earth today, which are living examples of what ancient microbial ecosystems could have looked like. Production of ...

2019年3月12日 · Stromatolites are layered forms of sedimentary rocks that are created by cyanobacteria. These sedimentary rocks occur as mounds, columns, and sheets, and are characterized by their distinct laminate structures.

Stromatolites document microbial interactions with sediments and flowing water throughout recorded Earth history and have the potential to illu-minate the long-term history of life and environments. Modern stroma-tolites, however, provide analogs to only a small subset of the structures preserved in Archean and Proterozoic carbonates.
