stromatolites

The Archean World, Peter Sawyer, The Smithsonian Institution

In the Archean, life is at its purest. No courtship, no conflict, no sleep, no song, no fear, no lust—just organisms, simplified to abstraction, thriving in poison, water, and ash. Life is not a substance, but a process: consume and continue.

Thermophiliacs feast on hot spring chemicals, relishing the heavy stink of sulphur, and kaleidoscope the steaming pool’s edges. Elsewhere, stromatolites, shallow-water plateaus of sediment and biofilm, learn photosynthesis, change the atmosphere, and terraform the dawn planet. 

The microbes are oblivious to anything outside of their own homeostasis, yet assemble into communities, unknowingly nestling cell walls against each other. Millions of lives surround each bacteria, but they only know their own, like a man running through the streets of Prague, bumping elbows with a thousand other lives—each rich with hope and love and loss—but thinking only of catching the 207 bus on time.

Early Cambrian Ocean

I want to make a series of images of prehistoric oceanscapes called Lost Oceans.  This is the early Cambrian feat. Anomalocaris, which you may know as the inspiration for the pokemon Anorith.  Other friends include various trilobites, Opabinia, Marella, Pikaia, Hallucigenia, crinoids (sea lillies), Kimberella, Wiwaxia, arcaeocyathid sponges, stromatolites, brachiopods, other invertebrates, and red algae.

Crystals for Bear Totem

Bears are certainly a majestic and powerful creature. Bear totem brings compassion and strength. Bear knows when it is time to rest and when it is time to take care of their loved ones. When Bear comes into your life, it is time to set boundaries, act on creative urges, and acknowledge your inner-potential.

These five stones help you connect with this powerful spirit animal:

  • Stromatolite - earth energy, ancient wisdom
  • Pyrite - protection, grounding
  • Snow Quartz - inner peace, wisdom
  • Honey Calcite - joy, change
  • Septarian - confidence, centering

No Longer Man’s : Soldier Uniform

Military forces may often have to move through Vastator inflicted areas, with the dangers of radiation, Stromatolites, Volarites, the Daemonus Donum virus, and eroding microbial cloud residue linger. Environ-suits are designed to reduce the risk of infection and radiation poisoning, with a filtration mask and thick layers of rubber fibers and resistant materials.
This crow model filtration helmet is designed with a “beak” to protect the filter from debris.
The lead plated coat is heavy, but makes soldiers invisible to Vastators and Volarites and even the microbial cloud, though the effect can be temporary the longer one stays in the eroding radius of a Vast.
Boot covers are often used to keep cold feet warm, or to just not tie one’s boots.

The Asinus Heavy Rifle is amongst many mass produced models of Anti-Volarite weaponry. This particular model requires a stand to aim in most cases due to it’s weight and kick back (which Asinus rifles are infamous for) and is shoulder mounted like an RPG. Its great at breaking through Volarite shells and rupturing innards.
In some cases these rifles are used to annoy Vastators in hopes of deterring them from civilian areas. Squads who perform these annoyance missions are often nicknamed Mosquito or Wasp teams and are often quite proud of their dangerous line of work, many getting tattoos or patches on their uniforms with team insignia.

Stromatolite layers

Since before the boring billion (as geologists jokingly call it, roughly 2-1 billion years ago), the main complex form of life consisted of microbial communities organised in mats that grew upwards, incorporating sediment from the surrounding sea. Made up of many kinds of bacteria and archaea, they form a layered community with aerobic bacteria at the surface and anaerobic ones feeding off their waste products below. Each layer of life ends up buried in the incorporated sediment, leading to a fresh one developing anew above. They still exist today in marginal brackish environments such as shark bay in Western Australia. In this stunning example (38,5x31x2,5 cm) found near Cochabamba in Bolivia, the layering that marks these communities has been beautifully picked out. We shared some time ago another example, replaced with red jasper (a mixture of silica and iron oxide rich mud) known as Mary Ellen jasper (see http://on.fb.me/1OCAiuq)

3.7 billion-year-old fossil found in Greenland may be the oldest sign of life

Fossils found on the coast of Greenland may be the oldest signs of life ever discovered, dating back 3.7 billion years. The stromatolites, fossils formed from ancient biomaterials called microbial mats, were found in Isua, a remote part of Greenland known for it’s absurdly old belt of rock formations. The finding may have implications out in the solar system too.
