I've been reading The 50 greatest prehistoric sites in the world by Barry Stone, so off I went to google for more info on the sites.

here are a few

Gabarnmung rock art, Australia, 46,000 BCE

Varna Necropolis - grave 43 - the bloke was covered in 1000 gold items!!

Nebelivka archaeological site in Ukraine

Arkaim archaeological site

Nuragic towers Sardinia

hypogeum Hal-Saflieni, Malta

Rujm El-Hiri Golan Heights

Heart of Neolithic Orkney UNESCO site

Jebel Hafeet tombs, Abu Dhabi

Shepsi and dolmens of North Caucasus

Sanxingdui, Sichuan, China

megaliths on Nias Island Indonesia - contemporary megolithic culture!

Prince of Glauberg - life-sized sandstone statue of a Celtic ruler

Bronze age battle field along Tollense River Germany - latest theory is that it was a massacre of merchants

I was hoping to find a list of the 50 sites, but all I can find how to buy the book, but I found this interesting site map, click on an icon & get the name of the site & google maps reference, very much on topic!
