Stromatolites (/ stroʊˈmætəˌlaɪts, strə -/ stroh-MAT-ə-lytes, strə-) [2][3] or stromatoliths (from Ancient Greek στρῶμα (strôma), GEN στρώματος (strṓmatos) 'layer, stratum' and λίθος (líthos) 'rock') [4] are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reduc...
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 dome-shaped.
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 well before more complex organisms appeared.
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...
Stromatolites are layered structures formed by the growth of cyanobacteria (formerly called blue-green algae) in shallow water environments. These microbial mats trap and bind sediment, creating distinct layered structures that can range from centimeters to meters in height.
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.
Stromatolites, also known as layered rocks, form in shallow waters when biofilms of living microorganisms, like cyanobacteria, trap sediment. Most stromatolites grow in extremely salty lagoons...
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.
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 ...
Stromatolites are microbial deposits with distinct stratification, built using detrital, mixed, or entirely calcareous material. They are centimeters to meters in height, with laminae ranging from millimeters to centimeters in size.
