Australian mega-fauna not done in by weather

However researchers aren’t exactly sure how the native population did it.

By dinking around with various dating systems, fossils & stalagmites in Naracoorte Caves, South Aus, have demonstrated a massively decreased population immediately after Aboriginal settler arrived.

What they’re completely unsure about is how these spear-armed settlers dealt with wombats the size of rhinocerouses — & ten-foot kangaroos — near the caves.

One theory is that burning removed a good deal of the foliage that these animals depended on, but as usual with Australian wildlife, they’re just plain uncertain. (-:
