Let's say I'm a secretive organization who's recently come into possession of two individuals of the genus, Giraffatitan (a sauropod similar to the more famous Brachiosaurus for those unfamiliar with it). Most other creatures that this organization comes into possession of aren't theoretically hard to find space for, but a 70 foot long, 40 ton animal is another matter from anything they've had to manage thus far.
This poses a problem, as, to remain in a generally healthy state, these massive animals need a lot of room to search for half a ton of vegetation per day. Keeping the animals indoors is theoretically possible, but pretty much impractical when compared to allowing them to be "free range", so to speak. The issue here, if this secretive organization wants most of its actions to remain hidden is that there aren't a lot of places that both provide a lot of space and are away from the public eye that are simultaneously on land and generally suitable to being Giraffatitan living space.
My question is this: Where on Earth could you let these two animals roam and feed themselves, tracking and managing their movements, without the public getting too suspicious? I've thought about somewhere in Central Africa or perhaps the fringes of the Amazon rainforest, but I'd like to hear other ideas on the matter. Here's an organized little list of the general requirements of the location.
- This place needs to be large enough for two very large animals to move around and do what they do.
- It needs to contain enough plant matter for them to survive.
- It needs to be suitably far enough from civilization that any potential prying eyes could be averted and/or covered up.
