The minute of life, “Underworld Ant” captures the cockroaches. Stored in amber for almost a hundred million years – Thai BBC
A research report published in the latest issue of the journal Current Biology reveals the results of studies of certain species of primitive insects. Who lived in the Cretaceous period one hundred million years ago It was analyzed from the fossils of “Hell Ant”, which holds its prey in a 99 million year old amber.
The amber has been found in Myanmar’s Kachin state since 2017, inside the amber is a fossil of an ant with large vertical jaws and bent like a dead sludge. Also in the posture while holding on to the ancestors’ offspring, a cockroach species.
The two ancient insects were both extinct. But the remains of this rare amber. It is evidence of an important stage of development that affects the species’ survival and extinction.
Dr. Philip Barden, senior team of paleontologists at the New Jersey Institute of Technology. (NJIT) in the United States Given that fossils are the first concrete evidence. Which confirms that “bog underworld” or whose scientific name is Haidomyrmecine It is the only ant with the lower jaw that rests and moves vertically. Unlike today’s ants, the jaws are transverse and move sideways.
Remains of the underworld ant in the amber block. With the help of a large sickle-like lower jaw, the victim is attached to the long horn in the forehead. Makes it easy to kill prey
The other underworld ants were discovered earlier. Use a metal horn to stab the victim and suck up the liquid from the courtyard, nodding Vlad the Impaler, as the origin of the vampire legend.
Dr. Barden pointed out that the existence of a strange vertical jaw Is like an evolutionary experiment To prove that it is easier to hunt prey in exchange for having large, vertical jaws, is it worth it? As a result, this unique organ restricts its main movement too much. And may be one of the causes of extinction Without any ant today after the development of this line
“99% of all life forms on earth have become extinct. And as we occasionally approach a sixth mass extinction, it is important to understand the species and nature of the diversity of extinction. To find out what determines life or death, said Dr. Barden.
