Argentine biologists have discovered the fossilized remains of a frog that lived in the center of this South American country about two million years ago, according to the science publishing agency at the National University of Matanza.
“We do not know much about prehistoric frogs,” said Federico Aniolan, a researcher at the Argentine Institute of Natural Sciences.
According to Agence France-Presse, the discovery took place at a depth of 44 meters during the drilling of a water well in San Pedro, 18 km north of Buenos Aires.
The researcher stressed that biologists have found “the bone of the humerus of a very small amphibian being different from the hulls and frogs of trees.”
He emphasized that the small fossil was identified despite its size because the petroats, which are a group of amphibians that include frogs and toads, have a special structure at the end of the humerus in the elbow joint.
This special structure provides it with great ductility to make quick movements and stability.
“The discovery is a major contribution to biology in Argentina,” said Federico Aniolan.
