What are the boned vivosours in Fossil Fighters champions?
After you beat the main story, fight Lola, ( standing in the
middle of Ribular Town)
Lester, (in the Cranial Isle fossil guild) and/or Cole ( just
standing in the middle of Illium village). Each gives you a
different prize pack and their own set of boneysaurs, and are easy
to beat, so go nuts!
