rhino tooth

I found this rhino tooth in the Spring. Its one of only a few known from NJ. I originally only found one half of the tooth, but I knew I broke it and the other half had to be around somewhere. So I went back a few days later and feverishly dug around for the rest because it would probably be lost forever if I did not find it on that day. It had been probably about 5 hours or so of digging in the same general vicinity without any luck, but then I found the other half unexpectedly and was able to go home very happy!
