Just so I am clear before commenting, are you claiming AC said the Cambrain explosion happened 5-10 million years ago, or that it only lasted 5-10 million years?

Only lasted 5-10 million years. The actual figure should be 10-30 or 10-40 million years.

I agree she stated that on page 220, but her book is well researched so I don't know how anyone could say she is definitely incorrect.
