Rear differential gears ripped to shreds

I have a 1995 300 fourtrax. Today I was riding it and I heard a loud pop, so I stopped and inspected it and started rolling it back and forth. The sound was coming from my rear diff. When I opened the oil cap there was broken peices of the gears coming out. I had oil in there. If you know what could have caused it, let me know. Thanks
