Paleozoic, e.g. (3)

Ross

I believe the answer is:

era

(Other definitions for era that I've seen before include "Age marked by a distinctive character" , "Important historical period" , "Memorable period" , "Series of years" , "Significant time" .)

I've seen this clue in The Wall Street Journal, The New York Times and the Penny Press.
