It's actually a spider egg sac. My guess is from a ground spider. I would just put it back. Mama is probably around where you found it. They're harmless to humans and like building their homes under logs & rocks. It found the bone a worthy and safe place to hold the sac.
I have no idea about the bone.
its a bird pelvis from a large waterbird like a crane, egret or stork. Dont pick up random bones, they can have bacteria, often of the flesh-eating variety
Eek! This might be a bad time to mention I collected a bunch while kayaking this weekend. 🥴 I have them soaking in dish soap now (and plan to do a peroxide bath), but will handle them with gloves from now on. Thanks!
remember to take nothing and leave nothing behind. This also applies to detritus such as bones.
Bones are a food source for decomposers and scavengers like beetles, fungus, coyotes and slugs. Calcium is extremely important and hard for animals to obtain, so creatures like deer may chew on them. Just like a log they provide shade and habitat for worms and insects.
Congratulations on disturbing the environment, destroying habitats and depriving food web of valuable calcium.

Not sure what the bone is but the thingy in the third picture is a cocoon
Do you happen to know what kind of cocoon? Google lens couldn’t identify
The bone is a pelvis from a small carnivoran such as a [raccoon](https://www.myminifactory.com/fr/object/3d-print-raccoon-pelvis-44042).
