Scientists discovered a piece of 蝾螈 amber 20 million years ago

According to foreign media reports, scientists have discovered a piece of amber amber 20 million years ago in the Dominican Republic, which contains a dead body of an ancient new species.


This cockroach belongs to an ancient species that has not been discovered. It was attacked by predators before death. This amber confirmed that it once lived on the Caribbean islands, although no other cockroaches were found in the Caribbean. Archaeologists hope that this discovery will fill the gap in the ecological and geological history of the Caribbean islands.

They pointed out that this short-lived cockroach was named "Palaeoplethodon hispaniolae". It lost its legs in the battle with predators 20 million years ago. When it struggled to escape, it was unfortunately wrapped in resin. Permanently stored in amber.

The research leader is a researcher from Ohio State University and the University of California at Berkeley. The results are published in the recently published journal of Paleontology.

Professor George Poinar of the Ohio State University Academy of Sciences, who specializes in animals and insects kept in amber, said: "When I first saw this amber, I was shocked. This is a rare ancient 蝾螈Species, which were previously not found in amber, have been found to be of special significance in the Dominican Republic because there are no surviving neoplasms in the area today."

This cockroach belongs to the non-pulmonary family, and there are non-pulmonary species in the North American region, especially the Appalachian Mountains. However, unlike modern cockroaches, its hind legs and front legs have squat-like toes with tiny protrusions. This suggests that they may not have the ability to climb like modern cockroaches.

The 蝾螈 amber was found in an amber mine in the northern mountains of the Dominican Republic. Poinner said: "The discovery suggests that the Caribbean has survived, but how they are extinct is still an unsolved mystery. They may Not adapted to certain climate events, or to some natural enemy predators."

At the same time, how this species of ticks reach the region is also a mystery, and the study suggests that early pedigree species originated in the tropical regions of the Americas. It is possible that the Caribbean geological plate drifted when it began to appear on the Caribbean islands.
