The origin of the animals and a 'Savannah'hypothesis for early bilaterian evolution
The earliest evolution of the animals remains a taxing biological problem, as all extant
clades are highly derived and the fossil record is not usually considered to be helpful. The …

[HTML][HTML] Resolving MISS conceptions and misconceptions: a geological approach to sedimentary surface textures generated by microbial and abiotic processes
The rock record contains a rich variety of sedimentary surface textures on siliciclastic
sandstone, siltstone and mudstone bedding planes. In recent years, an increasing number …

Microbially Induced Sedimentary Structures Recording an Ancient Ecosystem in the ca. 3.48 Billion-Year-Old Dresser Formation, Pilbara, Western Australia
Microbially induced sedimentary structures (MISS) result from the response of microbial
mats to physical sediment dynamics. MISS are cosmopolitan and found in many modern …

Names for trace fossils 2.0: theory and practice in ichnotaxonomy
A uniform approach to ichnotaxonomy has been for the most part positively received by the
scientific community. We carry it further here, presenting a revised treatment of trace fossil …

Large colonial organisms with coordinated growth in oxygenated environments 2.1 Gyr ago
The evidence for macroscopic life during the Palaeoproterozoic era (2.5–1.6 Gyr ago) is
controversial,,,,. Except for the nearly 2-Gyr–old coil-shaped fossil Grypania spiralis,, which …

A field guide to finding fossils on Mars
The Martian surface is cold, dry, exposed to biologically harmful radiation and apparently
barren today. Nevertheless, there is clear geological evidence for warmer, wetter intervals in …

Searching for biosignatures in sedimentary rocks from early Earth and Mars
The recognition of past habitable environments on Mars has increased the urgency to
understand biosignature preservation in and characterize analogues of these environments …

Formation and taphonomy of human footprints in microbial mats of present-day tidal-flat environments: implications for the study of fossil footprints
D Marty, A Strasser, CA Meyer - Ichnos, 2009 - Taylor & Francis
This study concerns the formation, taphonomy, and preservation of human footprints in
microbial mats of present-day tidal-flat environments. Due to differences in water content …

Morphological adaptations of 3.22 Ga-old tufted microbial mats to Archean coastal habitats (Moodies group, Barberton Greenstone Belt, South Africa)
Microbial life was well established and widespread by the Paleoarchean; however, the
degree of evolutionary advancement such as microbial motility, intra-and inter-species …
