Biologists call the area a bio-fortress. The park is so impassable and uncharted, in fact, that every time a team goes on an expedition there, they find approximately five new species. They're literally tripping over entirely unseen life-forms -- a photographer for National Geographic documented these creatures, presumably while picking crocodile-headed lizards out of his canteen and shaking bizarre, dancing crimson bugs out of his sleeping bag.
Sometimes a forest of daggers just isn't enough.
It shouldn't be surprising: 90 percent of all species found on Madagascar are endemic, so if we go vaulting over the Earth's barbed-wire fence on the Island of Extremely Rare Shit, we're probably going to see some new things. And yet despite all of that sweet groundbreaking science temptation, the vast majority of the park remains completely unexplored to this day.
So yeah. There are definitely dinosaurs in there.
