Broken A833OD

I was getting ready to install my A833OD back into my Duster & decided to replace the pilot gasket/seal & side cover gasket. When I got the cover off I found this critter on the bottom. Just wondering if anyone has any idea which component it's from. I plan on disassembling it all but not exactly sure when that's gonna happen now. Talk about taking the wind outta my sails!!
