That was my thought as well (and it's probably the actual first reason for burial practices), but the caving required to get to the "burial chamber" in this cave is a bit interesting.
The Superman's Crawl may not have been so tight back then, but as far as they can tell, the ceiling beyond it has stayed intact, and the Dragon's Back could not have grown up in a million years. So it's likely that this is basically the same cave that it used to be. The chamber is a great place to put a body to conceal the smell, but imagine how this little caving journey becomes a sort of ritual over time. They had to take some care with their dead. Hopefully they excavate some of the chamber just before the burial chamber to determine whether bodies were once left there and then later moved. Linking early, intentional burial practices with hominids is a fucking spectacular find.
