How old is the Monsterverse Godzilla?

How old is Godzilla in the Monsterverse? The novel Godzilla: Awakening shows Godzilla existing as late as 250 million years ago. Some sources place him at 252 million years old approximately, but there aren’t any notable records or canon literature to give us a concrete age. 252 million years old seems to make sense however, given the timeframe referenced in Godzilla: Awakening. 

It’s possible Godzilla x Kong: The New Empire may explore this question, but we’re not sure.
