When I visited my good friend, Ralph Collier in Los Angeles, a few weeks ago, I managed to bring back with me a couple of his jaws to restore.
Amongst the topic of discussion were sharks (of course) and shark jaws.
Ralph showed me a couple of small jaws he had since the early 80’s, and of course once I looked at them I decided I could improve their current condition.
The jaws were a Mako (Isurus oxyrhinchus) and a Silky shark (Carcharhinus falciformis), both very small.
It appears that at least the Mako jaw may have been cleaned in bleach, as the cartilage appeared to be quite thin and slightly brittle.
After soaking in water, I placed them in my special whitening and disinfecting solution for a day, removed and placed them on a drying board for a couple of weeks.
The photos below show the jaws as I took them off the drying board. I will update the photos when I finish them.
