The September 2011 issue of Geoscience Canada carried an article by Andrew Miall entitled “A Phanerozoic Time Chart for Canada”; however, the cover of that issue incorrectly transcribed “Phanerozoic” as “Proterozoic”. We regret the error and extend our apologies to Dr. Miall.

The author would like to point out that readers desiring to copy the chart for their own use or distribute it to classes for educational purposes are free to do so. A .jpg file for the chart, which is designed to print out on legal-sized paper, may be obtained from Dr. Miall.
