Setting
The Spino Swamplands consist mostly of non dinosaur creatures like sarcosuchus or postosuchus, dragonflies, fish. But of course there are dinosaurs there and the place is known for spinosaurus. Baryonyx also thrive there, and sometimes other dinosaurs not made for swamps stay there, but they usually don't last long.
The swamps also have a few strange caves here and there, nothing much inside them but sleeping dinosaurs, but some guilds live near these.
