Preserved ‘Hell Ant’ has destroyed its prey 99 million years ago


A prehistoric “helmet” in the middle of grabbing its prey with its unusual mouths has been found preserved in 99 million year old amber. According to ScienceAlert, the frozen specimen catches the predator “active food” on another insect, which is said to be an extinct relative of the cockroach. It is displayed with its shear-like jaw to pin its prey against the protruding horn-like paddle at the top of the head, and acts as a sort of clamp.Hell Ant Fossil

While the mandibles of modern ants and almost all other living hexapods move on a horizontal axis, this new evidence indicates that ants used their lower mandibles to move upward in a vertical motion as part of their predatory strategy.

“Fossilized behavior is very rare, predation especially so,” said Phillip Barden, an assistant professor at the New Jersey Institute of Technology who served as lead author on this new study, which was published in the journal Current Biology. “As paleontologists, we speculate about the function of ancient adaptations using available evidence, but to see an extinct predator caught in the act of catching its prey is invaluable.”This newly identified species of prehistoric ant, known as Ceratomyrmex ellenbergeri, is just one of more than 12,500 different species of insect that scientists have discovered so far, although they believe there is “probably another 10,000 or so” there, waiting to be identified to join the ranks of this diverse collection of complex creatures.
