Studying Life Before the Cambrian Explosion

The elements of Precambrian paleontology

$On the left is me at an outcrop near the site in Kakabeka Falls National Park where, in 1954, geologist Stanley Tyler collected a piece of black chert (aka flint rock) from a geologic unit called the Gunflint Formation. That 1.9 billion-year-old rock turned out to contain the first widely accepted evidence of Precambrian life. On the right is the picture I was taking in the photo on the left. The waxy appearance and curved fractures of this (red arrow) rock layer indicate that it is microcrystal$

NASA Found Possible Signs of Ancient Life on Mars

NASA found a rock that needs a much closer look than the rover can give in the search for life on Mars

An image of the portion of Jezero Crater, Mars that is being explored by the Mars 2020 Science Team. The base image, including the scale bar, was created using NASA’s publicly available Perseverance Rover Location Map tool. The geological feature labels and arrow were added by the author. The white arrow indicates the approximate location of the Cheyava Falls sample within Neretva Vallis.
