Green raptors are more powerful than the first raptors encountered in Prehistoria. They are quick and will often seek out the player. They have the most health of all the creatures to be found in Prehistoria outside of the Volcano, and as such, caution must be exercised in dealing with them.
Raptors offer a fair amount of experience, though not nearly as much as widowmakers. However, players interested in earning Talons would do well to engage as many raptors as possible, as the raptor drops a lot of them.
