“Massage” 99 million years ago

  Recently, scientists discovered a long-extinct insect-“hell ant” in a piece of amber that was 99 million years ago. In the amber, the ant is holding its prey with its sickle-like jaw. This sealed hunt instantly surprised scientists. This prehistoric ant is a fierce predator, this is the first time scientists have seen it hunting prey. The prey of ants in amber is an extinct “relative” of cockroaches.
  The mouthparts of “hell ants” are different from the mouthparts of most insects today. “Hell ants” use their lower jaws to move upward and pin their prey to the horns above their mouthparts. Scientists believe that this horn may be a kind of clip, and this 99 million-year-old piece of amber is the first evidence to support this claim.
  Unlike “hell ants”, modern ants’ jaws can only move horizontally. In addition, modern ants have their mouths facing forward, which makes their heads parallel to the ground, which makes it easier for them to look around. The “hell ants” cannot turn their heads as flexibly as modern ants. They are likely to prey with their mouth down. This may also be the reason why the “hell ants” have become extinct after nearly 20 million years.
