I appreciate what you are trying to say, however, consider simple human anatomy. Look at the following diagram of a human skull and note where the mandible attaches:

Then consider whether a few small overlapping pieces of duct tape would have been enough to keep those two pieces of bone -- which have no articulating pieces -- together. The flesh had long since decayed. No ligaments or tissues of any sort to provide any support. And in spite of that, both of those pieces of bone were located together, in approximate anatomical position, after all the animal activity, after the decomp and nature took it's toll. The only reasonable conclusion is that the tape was placed close enough to the articlulation point of the mandible and the skull, forcefully enough to withstand ALL the elements mentioned previously. The tape went at least beyond her ears, IMO, or else the mandible would have dropped off or been carried off by animals. Think about it logically. These two pieces of bone had NO REASON to be together, yet they were fastened together in such a manner that they remained together, despite the elements. The tape did NOT have to be completely wrapped around her skull to accomplish this, however, if you look at the diagram of the skull you can reasonably see that they were not small pieces of tape...
