i'm undecided on this, but i don't see how we'd have instruments to measure holes in the ozone more than a century ago. unless they leave a mark somewhere; tree rings, geology...
I'm not sure either, though I have read work on paleo-atmospheres. I recall the evidence as coming from rock and water samples from cores. We also learn of paleo-environments from things like crude oil:
