Dr. Stone is a new anime that has started this season.
I've only watched the first episode as it's the only one out so far but the show already looks like it's going to be a winner.
Basically, one day, everyone turns to stone. The world of humans halts. The main characters seem to survive being turned to stone (somehow) and find themselves over 3000 years into the future, apparently having to rebuild civilization from scratch.
It looks like it's going to be really good. I'll update after a few more episodes have come out.
