I had not heard of Shuruppak, but now I’ve pulled up Wikipedia on it. Thanks for the info!

I love learning about history but hadn’t focused on this aspect of human history until pretty recently, so I’m happy to learn more. It was when I got various dates put to farming and domestication that I began taking note of civs in this / these eras. I’d primarily focused before and after previously (evolution of hominids and post-middle ages). Again, thanks!
