I think this is all pointing to a new map. If I am correct, all of the dossiers point to creatures that could sustain you in a desert. If it were a new biome on a current map, you would just fly to another biome to get oil. Why are we getting a new flyer, that is desert themed? No other biome has had so many new dinos get released with it, and so much hype for it. This is why I think it is a new desert map.
