Perhaps people would rather go out and spend the $95 to buy the book from which I obtained my information.
Here are the particulars, though, in case anyone is interested.
Title: Historical Geology
Edition: Fourth
Authors: Wicander/Monroe
Publisher: Brooks/Cole, a division of Thompson
From here I obtained my information. If anyone has any information refuting mine, I would appreciate seeing a link or book title so that I might receive enlightenment, rather than remain in ignorance.
Thank you.
