Headings

Thomas, standard top-level headings are two equals signs; bold is not necessary. The reason it's two and not one is that single equals signs produce headings that are the same size as the title of the article --Larry Sanger 21:23, 15 April 2007 (CDT)

Hi Larry, Right. Caught that after I had switched them back. Thought it was my oversight. But I reverted them. All article headings start at double equals and work down from there. Thanks for the tip. - Thomas Simmons 14:33 18 April, 2007 (EPT)

Change title to 'Geologic time scale'?

Could we change the title of this article? To "Geologic time scale", I suggest. There are at least two reasons for this.

First, the description and classification of geologic time is usually found in Geologic time scales (what I also mean is that books about this topic are traditionally titled "Gologic time scale <year>", e.g., Gradstein F.M., Ogg J.G. and Smith A.G., 2004, A Geologic Time Scale 2004, Cambridge University Press).

Second, age has, in stratigraphy, a precise meaning. Strictly speaking, the article "Geologic ages of earth history" should thus be a list of ages.

This article is quite important for Earth Sciences. It might evolve into a description of the geologic time OR to a timeline of event in geologic time. I'll contribute soon (as soon as I can find the time). Thanks for starting it, for now! --Nereo Preto 01:57, 18 April 2007 (CDT)
