That whole area is basically a strewnfield though.

Damn. And there's this.

Homo erectus

Archeological artifacts found with these tektites in Baise, Guangxi in southern China indicate that a Homo erectus population was living in the area during and after the impact. Stone tools have been found within the debris field along with a charcoal layer likely caused by fires from the impact. It has been suggested that the subsequent local deforestation after the fires allowed this population easier access to stones useful for tool-making.
