Daxian Cave

This cave is the holy grail of Giganto exploration because it was the location that the first evidence of Giganto was actually found within the sediments (rather than in a drug store in Hong Kong!). This cave was very high up - blood sweat and tears were shed just to arrive at the entrance. Its possible that this cave contained Giganto evidence that is very old. However, the basal layers have Giganto whereas the upper layers do not so it's quite possible that the cave contains the point at which Giganto drops out of the fossil record and therefore the secret to it's demise.
