[edit] Ma vs. mya
In these era pages I have seen "million years ago" abbreviated as Ma and as mya. Which one is the standard?
- If the Mya (unit) article is to be believed, Ma has replaced the older Mya in scientific literature. Because of that I think we should use only Ma.--Jyril 20:23, 26 February 2006 (UTC)

- There should be an agreed on convention regarding this notation somewhere, as I know it's been brought up before. I'd like to know as well, so if I find it, I'll leave a note here. --DanielCD 22:08, 26 February 2006 (UTC)

- Ma is certainly the standard in professional geologic circles. Cheers Geologyguy 23:54, 10 March 2007 (UTC)
