What word means a million years?
Megaannum; the abbreviation is Ma.
What is one million years called?
I think the answer you are looking for is: 1 Million Years = 1 mellophone
What is the name for 1 million years?
Google! No, that's one, followed by a hundred zeros, and a super-easy way to get info. Megaannum!
What do you call 1000000 years?
A period of one million years is commonly referred to as a "megaannum" (Ma) in scientific contexts, particularly in geology and astronomy. It is also sometimes simply called a "million years." This term is often used when discussing geological time scales or the age of the Earth and other celestial bodies.

Is there a unit of time bigger than Millennium that still measures years?
According to Wikipedia (http://www.reference.com/browse/wiki/Annum) megaannum, usual symbol Ma, is a unit of time equal to one million (106) years. It is commonly used in scientific disciplines such as geology, paleontology, and celestial mechanics to signify very long time periods in the past. For example, the dinosaur species Tyrannosaurus rex was abundant approximately 65 Ma (65 million years) ago (ago may not always be mentioned; if the quantity is specified while not explicitly discussing a duration, one can assume that "ago" is implied; "mya" includes "ago" explicitly.). In astronomical applications, the year used is the Julian year of precisely 365.25 days. * gigaannum, usual symbol Ga, is a unit of time equal to one (short scale) billion (109) years. It is commonly used in scientific disciplines such as cosmology and geology to signify extremely long time periods in the past. For example, the formation of the Earth occurred approximately 4.57 Ga (4.57 billion years) ago. * exaannum, usual symbol Ea, is a unit of time equal to (1018) years (one quintillion on the short scale, one trillion on the long scale). It is an extremely long unit of time. The half-life of tungsten-180 is 1.8 Ea.
