What does the geological term Ma mean?
Ma in geology means Mega Anum. The M is a standard SI prefix (think giga, mega, kilo, etc.), and anum means year. However, in geology the "a" specifically denotes time before the present. For example, 10 Ma means ten millions years before the present, or ten million years ago. This distinction is important because the symbol Myr is used for a million years, as well ("yr" is the abbreviation for year, similar to "s" for second or "hr" for hour). Using the "yr," however, does not denote relation to the present and instead refers to an arbitrary length of time. For example, the Triassic began about 250 Ma and ended 200 Ma, and it only lasted about 50 Myr. So it began about 250 million years ago (Ma) and lasted for fifty millions years (Myr).
