I received a Great White shark jaw from a client a couple of weeks ago. At first sight I was amazed at the sheer size of this jaw and in what a great state it was in, despite its years.
The jaw appeared to be probably from the 70’s , as the way it was mounted and the state of the jaw pointed to that. The teeth were in remarkably good condition, with only a couple of broken teeth on the bottom jaw
The measurements of this jaw are quite breathtaking. The dried upper jaw perimeter (DUJP is 1225.25mm and the dried lower jaw perimeter (DLJP) is 1026.3mm. The UA1H of the first upper tooth on the left is a whopping 64.44mm.
The jaw is quite old, and there are a number of areas which are damaged. Unfortunately, after soaking, these cracks and holes will become more extensive and will require quite a bit of repair work to be carried out on the jaw.
Very little is known of the history of this jaw, and hopefully the owner will be able to trace it back one of these days.
Further measurements will be taken on this jaw, as its size is nearing record sized Great White sharks which have been caught in the past. There will be some shrinkage after the jaw is dried, however I expect it not to be any more than 8% to 10%. It is going to be very exciting to compare this jaw with other accurately measured jaws in the world’s databank.
