"There are indeed many unanswered questions of why a single 'Woolly Mammoth Tusk' may be frozen in state, within Pleistocene permafrost as if it had been lost in wind blown glacier silt and deposited in this Ice Age mud, frozen indefinitely until it had been discovered. A 'shaking' had occurred dislodging the tusk from it's skull and remaining skeletal as no doubt been scattered by water currents and flows during some point in it's unrecorded history. I, like many others, do refer to the findings of paleontological field work to arrive at some explanation with just a logical point of view, understanding these as ancient deposits, or secondary depositions of a scattered deposit. Primary depositions are evident that the skeletal remains are usually found in very close proximity, not drifting too far from it's original state of it's frozen location and never have been exposed more than once. This tusk illustrates a 'right-sided' tusk of a bull Mammoth frozen in situ.  The mud that has it surrounded in ice, and as strong as concrete, relys on the thawing of the ice to dislodge it from it's position."
