Bone Shards are dropped after attempting to open the Loot Stash with the Deer Antler, causing Klaus and his two Gem Deer to spawn. Killing a No-Eyed Deer with an Antler has a 50% probability to drop a Bone Shard. Hammering Sea Bones will drop two Bone Shards with a 50% probability for an additional third Bone Shard to drop. In addition, hammering a Spoiled Fish and a Spoiled Fish Morsel will result in a 100% and 50% chance of dropping Bone Shards, respectively. Using Deconstruction Staff on Bone Helm and Bone Armor will yield 10 Bone Shards.
Additionally, Bone Shards can be crafted by Wilson if he has unlocked Transmute Icky Ⅲ in his Skill Tree. It requires 2 Hound's Teeth to be crafted in this way. Wilson with said Skill can also use 2 Bone Shards to craft 1 Hound's Tooth.
