Just keep hunting monsters. You get really weird monster bones near the end.
You get a large monster bone from the large monsters like the kut-ku.
4*+ Elder quests. If I recall correctly, the Green Plesioth awarded Monster Bone+.
You can get them by killing monsters with shells in the dessert.
Kill the things with spicky tails in the desert

This isn't a question but a incomplete sentence, and there is no such item, bone, or weapon called big bone.
Most medium sized monsters drop them, but I think the best way is to kill apcerpos in the desert or volcano.
By hunting a khezu, rathalos, rathian etc... The first time I got any monster bone +, it was when I got 3 of them from one run of the 5* village quest "Small Shadow over the Swamp".
In Monster Hunter Freedom, Hard Monster Bone can be obtained by breaking certain monster parts. To increase your chances of obtaining Hard Monster Bone, focus on targeting specific parts of monsters that are known to drop this material, such as the head or back. Additionally, using weapons with high impact damage, such as hammers or hunting horns, can help break these parts more effectively. Good luck in your hunts!
