After you finish the game, you have to beat Saurhead in his triple match. [I'm still trying to beat him in the 3rd match with my strongest ones and it's still not working!]
for the first time go to mt lavaflow, to keep it forever beat the game then defeat saurhead in the 3 battle fossil fight in the common room of the fossil stadiam
get beaten by bb boss second time u battle him and keep talking to rosie in jail cell and rex will let u out and the u have 2 go deep in mt lavaflow and find igno fossil.
Ignosaurus- Beat SaurHead 3 times Frigisaurus-Beat the BB Bandits in the BB Base Duna,Raptin and DynaliBeat Dyanal in the space ship for the second time Gunash three Brains-use the time machine and beat Gunash again
beat dynal the third time and he will join
You need to have lots of fossil parts ( Head, Arms, Legs and Body ) and clean them WELL, fight many fossil fighters and you'll have lots of skill in no time! (Rank up !) DONE!!!
