This fossil formation, called the Burgess Shale, is in Yoho National Park in the Canadian Rocky Mountains of British Columbia. Shortly after the Cambrian explosion, mud slides rapidly buried thousands of marine animals under conditions that favored fossilization. These fossil beds provide evidence of ...

The magnetic field preserves the atmosphere, which is the main shield of UV radiation. We explore the hypothesis that the Cambrian explosion of life could have been enabled by the increase of the magnetic field dipole intensity due to the solidification of the inner core, caused by the cooling...
The DigiBarn Computer Museum seeks to capture personal stories and track technological evolution through a large collection of vintage computer systems, manuals, videos, interviews, and other fossil relics of the "Cambrian explosion" of personal computing that ignited in 1975.
