Ancient 'lost city' of the Khmer Empire uncovered in Cambodia

I know there have been a number of discoveries over the last fifty years. This one looks quite significant. A great example of how invaluable the current mapping technology is.

The 1960s saw renewed interest in the region. Hansen (1969) and Boulbet (Boulbet & Dagens 1973; Boulbet 1979) added various elements to Stern's archaeological map, in particular water-control structures, dykes and other linear features, without necessarily adding support to the notion of an urban network. Aerial mapping campaigns of the Angkor region throughout the 1990s extended northward to the mountains, but with limited success. While radar imaging provided additional detail around the base of the mountain range, the dense foliage could not be penetrated, and Phnom Kulen remained a lacuna on archaeological maps (Evans et al. 2007).

So a lost temple not a city
Slight difference between a temple and a city

Wouldn’t be surprised what they could find in that dense jungle
Dinosaurs on the wall carved in by people who should never have seen a dinosaur or know what they looked like

Edit
Yes seems a city, swallowed by the jungle, only 500 years ago, so recent
