Here is more on the July find which was described as a feasting area.
I am not so sure its the same one. The scientists are supposed to be on a three year search which started around July. It doesn't make sense that the same find would be current news on January 31.
Below is the phys.org coverage of the July discovery. It suggests that the discovery was per scans of the area (evidently by ground penatrating radar). The current article (also by phys.org) is probably about the discovery in unearthed condition.
