Putative stromatolites and associated carbonate minerals in 1.1 Ga Stoer Group lacustrine sedimentary rocks were analysed to deduce their likely origins. Potential stromatolite examples included finely laminated and sometimes wrinkled carbonate-silic

Summary Sediments of the Torridonian sequence of the Northwest Scottish Highlands contain a wide array of microfossils, documenting life in a non-marine setting a billion years ago (1 Ga).1–4 Phosphate nodules from the Diabaig Formation at Loch Tor

Filamentous microstructures from the 3.46 billion year (Ga)-old Apex chert of Western Australia have been interpreted as remnants of Earth's oldest cellular life, but their purported biological nature has been robustly questioned on numerous occasion

Filamentous microstructures in 3.46 billion-year-old rocks (Apex chert) from Western Australia have been claimed to represent the oldest morphological evidence of life on Earth [1]. However, the biological nature of these filaments has been questione

Fusiform planispiral tests are found in many lineages of larger foraminifera (e.g. fusulinids, lituolids, alveolinids, soritids, amphisteginids) in which a general trend from spherical or discoidal to elongate test shape has often been noted. Geometr

Geometrical models of unit volume are used to examine the effects of differing rates of chamber or test volume expansion, growth plan, chamber shape and apertural form upon internal-external lines of communication within foraminiferid tests. The main
