Tree rings show that vegetation growth slowed down in around 207BC, possibly because of the “nuclear winter” effect of dust blotting out the sun.

So did this happen after Tunguska, as well?

Well... no.
No trace has been found at Tunguska of any remnants of the object, that I know of. The conclusion is that the object "vaporized" and no traces struck earth.

Sorry, Tunguska was an air burst, albeit a very spectacular one.

Can you imagine if something similar were to happen today, especially over a populated area?

They think the Russian hit was an air burst or glancing blow. The object didn't hit the earth, just the shock wave. Its the impact that throws back up the dust. Because of that there was no large scale blockage of the sun.

No...
Tunguska occurred at the turn of the century, approx. 1900 CE... 100 years ago..
Roman Comet happened approx. 2,200 years ago.. 200-250 BCE..

Even at 2,200 years ago, that would make it one of the most recent major asteroid /comet impacts in history..
