Things You'll Need
Instructions
Travel to the East Dust Hills, where you'll encounter a woman blocking the path to town. Speak to her and she'll stand down and admit you into town.
Follow the path into town and head east when the path branches. Follow the path to its end, where you'll encounter a troubled man.
Speak to the troubled man and give him water when he asks for a drink. Accept the man's reward for rescuing him -- a upgrading gemstone.
Use the gemstone to upgrade your drill and radar by pressing "Start," pressing "R" to access your inventory, highlighting the newly acquired gem using the directional pad and pressing "A" to initiate the upgrade.
Press "Start" to exist the inventory screen and then press "R" to display the radar on the top DS screen. Follow the radar to the orange blinking dots and press "L" to dig after you arrive.
Dig up all the spots that are indicated by the radar in the East Dust Hills until you find Ankylosaurus.
