I'm making an assumption based on how you typed it, but were you holding him down with one hand, and prying on the pine cone with the other until he finally let it go just enough for you to drag it out?
If that is the case, then you're not pinning him properly, and he bit you because he's even more protective now.
This method is not for everyone. As you saw it can lead to a bite because it challenges the dog. The way it's suppose to work is the dog calms down and drops it on his own accord.
You're not trying to overpower his body, you're telling his brain to submit.
If you're angry, don't bother trying. It has to be done with a clear head. Deep breaths help a lot. You'll know you've come far enough when you can lift your hand or finger off completely, and the dog stays put until you release. It should be a calm situation, not a fight.
If pinning him is not something you're comfortable with, then try some positive reinforcement techniques like mentioned above, and/or seek professional advice. I know he is just a pup, but there is reason to be concerned. Adult dogs who are aggressive don't wake up one day and decide to be bad dogs. We make them that way.
There isn't any one step that will fix the problem. It comes down to everything you do and how you do it. Making him sit before he eats, being able to put your hands in his food, and getting him to stop eating, are all things you should be able to do at his age.
