This is the Forgotten Realms, and dealing withthe Jungles of Chult. You don't know the Realms that much do you? The Jungles of Chult, as with many other jungle and tropical regions of Abeir-Toril, have a rather large dinosaur population. Know your Realms Lore before making posts like this. It will make you look less ignorant. Though the Realms do lack barbaric halfings riding dinos, unlike Eberron, which is sad.
