A long-extinct lineage of insect, known fondly as the 'hell ant', has been discovered frozen in 99-million-year-old amber, with its scythe-like jaw still pinning its prey.
According to scientists, this fierce predator is a newly identified species of prehistoric ant, known as Ceratomyrmex ellenbergeri, and it's the first time we've ever seen a hell ant actively feeding. Its meal is an extinct relative of the cockroach.
