I have a leopard tortoise with a beautiful shell. The poor gal died last week and we buried her in our backyard. One day I would like to dig the shell up when it has completely decayed. Does any one has any experience with decaying things? I know it all sounds weird but I sure like to recover it as something to remember her by. I tried it once when I was about 12. Pet turtle died and I buried it. I dug it up too soon so I reburied it. Months passed by and I forgot where I buried the turtle. Anyway, has anyone done this?
