Personally, I'm hoping for at least 2 of these dinos we haven't seen yet.
Rock/Dark- Velociraptor (Ridiculously High Speed, low Hp, low/medium Defenses, Avg/low Attack, High Special Attack)
Rock/Electric- Stegasuarus (High Hp & Defense, Avg/good Attack & Special Attack, Very low Special Defense, Low Speed)
Pure rock- Spinosaurus (Very High Attack, Avg Defense & Special Defense, Medium/Low Speed, Pitiful Special Attack)
Rock/Fighting- Pachycephalosaurus [The headbutting dinosaur] (Low/Avg Hp, Ridiculously high Attack, Good/High Attack, Good Defense, Low Special Attack, Pitiful Special Defense, Low/Avg Speed)
