[edit] 2500 MYA?

Would it be more correct to say 2.5 billion years ago rather than 2,500 million years ago?--68.202.47.225 03:34, 17 July 2006 (UTC)

Yes and no, not everyone in the world has the same definition of billion, see Long and short scales, which can make things confusing for some readers.--Peta 03:38, 17 July 2006 (UTC)
