The Age of Dinosaurs is the time where large reptiles roamed the Earth. It was the time where bigger meant better.
This region contains a crystal that describes the new features of a reptile. Specifically, two-legged reptiles have a better jump, while four-legged reptiles have a better defense.
From here, you can either head through the Marsh of Prime Frog or through the Domain of Tecodonto. Either path will lead to the Domain of Syrocosaurus.
The northern path contains amphibians watching over the plants and insects. The frogs here have a tongue attack, and unlike most other creatures, can quickly counter attack with their tongue before you can bite them a second time.
This marsh is filled with slightly more aggressive versions of the bull ikustega. However, they provide 15 EVO points each.
The tecodonto will try to run away from you, but will retaliate any attack you make against them. Worth 12 EVO points each.
The polsaurus will show off their head-butt by ramming each other. The best way to collect 20 EVO points from each one is to eat them as they focus on another Polsaurus for their headbutt.
If no other Polsaurus is nearby, they are willing to charge toward you.
The sole inhabitant of this region is an adult syrocosaurus, who is angry because his child is missing. Walk to the right (without attacking) to proceed, as the syrocosaurus will retaliate against any attack.
While the plant eaters are passive, they are large and powerful enough to slow you down. Attacking them a few times will aggravate them, causing them to swing their tail at you and continue attacking. Your best means to get past is to jump over their body using a tail (or similar) upgrade.
The Prasauro will retaliate any attack with a loud scream. However, they are worth 50 EVO each.
The segosaurus has a tail swipe, and also an armored back that prevents you from jumping over it. They are worth 80 EVO each.
In this area, you will see two frogs teasing a young Syrocosaurus. Chase them off the right of the screen, then re-enter the area.
The Prime Frog has two attacks:
The small frogs provide a constant stream of EVO points that can be used to either evolve further, or to instantly heal by taking a minor evolution.
The Prime Frog can be locked down indefinitely with well-timed bites.
Compared to the Prime Frog, you should have no trouble collecting 90 EVO points form each Tritops.
This is a swimming region. While the Plesaurus is not too difficult, it is able to use a long neck to attack.
If you want to obtain a bird body, you will need to scale the mountain. Since this requires a lot of jumping, you should improve either your tail or evolve into using two legs.
Once you reach the top, you can jump off the side to obtain the bird's body.
The Pronesaurus is heavily armored, and retaliates any attacks. It is not worth eating.
The Omosaurus is the second most powerful creature in the area. This is the best place to collect EVO points before heading to the final location.
This is the final region within the age of dinosaurs. Your objective is to eliminate approximately 10 tyrosauruses. The most effective evolution for this section is an extended neck, which negates almost any threat from enemy attacks.
While the Tyrosauruses give the option of joining them, it is only for entertainment purposes. As shown in the following cutscene, the dinosaurs were wiped out by the meteor that caused the Ice Age.
To enter this location, you must have evolved as a bird from Mount Brave. A few Deltadiums will walk across the surface.
When the dark cloud hovers over Mt. Hidden Mammals, you will fly into it. The maze contains a red crystal allowing you to transform into a dragon.
To reach it, head up at the first junction, right at the second, and continue right as the third junction. Eat the crystal, and return in the same path.
