So I need the Location of Skull Rex, and I need the appearence rate (rare or not). Also please tell me where to find Voltiger ( lower evolutions) Also if you could, i need the location of that Earth dinosaur, geosauros or something. Thanks!
I fixed your posts. Remember that there is an edit button to the bottom right of your post for just such occasions 
Unfortunately, I can’t help you with the monster locations as I can’t remember them off the top of my head at the moment but I’ll let you know if I recall them unless someone else can give you answers.
Ahh, never realized that! Thanks for your assistance tho
Skullrex is at the northern tip of the north forest on Crescent Island or in Ryudou Cave west of batek
Voltyke is by the River East of Malden
Rexy is found to the south west of Ergan, West of the cave
