This ancient species had the same six legs and segmented body that we’d recognize from an ant today. But it also had a huge, scythelike jaw and a horn coming out of its head. This bizarre predator belonged to a group known as “hell ants.” But they’re gone now, and we’re still trying to figure out why.

Please see the pinned comment for a disclaimer on the ethical issues surrounding Burmese amber in paleontology.
