Very long period (3)

Ross

I believe the answer is:

eon

'very long period' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for eon that I've seen before include "Long period of time" , "Vast period" , "In time, long division" , "An immense time" , "thousand million years" .)

I've seen this clue in the Newsday.
