Highly fractionated chromium isotopes in Mesoproterozoic-aged shales and atmospheric oxygen

Highly fractionated chromium isotopes in Mesoproterozoic-aged shales and atmospheric oxygen

There is a long standing debate whether low atmospheric oxygen levels during the Mesoproterozoic Era hindered the evolution of crown-group animals. Here, the authors show with shale-hosted chromium isotopes that sufficient atmospheric oxygen for crown-group animals likely predated their evolution by...

description There is a long standing debate whether low atmospheric oxygen levels during the Mesoproterozoic Era hindered the evolution of crown-group animals. Here, the authors show with shale-hosted chromium isotopes that sufficient atmospheric oxygen for crown-group animals likely predated their evolution by over 400 million years.
