Maybe the crown wheel ring? Try whether it fits on the crown wheel post and if it does see whether the crown wheel fits on it.

Ya,  Looks like the crown wheel ring. 

No panic, just don,t loose any parts, give it a good clean, will work with you for reassembly. Easy easy.

Yes the boys are right it is the crown wheel bearing, I took some shots for you so the parts will go into correct place.
You also have to remember the screw for these parts is left threaded, it will tighten if you turn the screwdriver anti clockwise, rotate to the left.
Just a frienly tip, always try to organize the parts in the same way as you took them of use small containers, wash them in the same fashion, being organized and methodical is one of the keys to success.
Below is how a small diary could look like... Just snapp and pop with the camera as you go all pictures of the process is valuble in the end.
