[edit] Shaly?

The article characterizes the Johnnie Formation as "varicolored shaly". Is "shaly" not an adjective awaiting a noun? Or should the word be "shale"? Myron 09:23:09, 2005-08-08 (UTC)

[edit] Regarding timelines

Forgive my ignorance, but why does the article read "1700 million years ago" instead of "1.7 billion years ago"? Is that a common use in geology? --Ignis33 17:03, August 8, 2005 (UTC)

Yes, very common. 'Billion' is also a bit ambiguous. --mav 00:18, 9 August 2005 (UTC)
