First you have to get a oasis seed for 20000 G. Then give it to the old man and then wait for a while or battle someone. Then the todays special will be here again and buy the oasis seed for 20000 G. Then give to the old man. Reapeat that until you gave 4 seeds to the old man. Then go back and the old man will tell you the fossils that you can find there. Go to where the old man is and search for the T-rex head. Warning(this may take up to 3 hours).
