Argentine scientists 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 Matansa.  "We don't know much about prehistoric frogs," said Federico Aniolan, a researcher with the Argentine Institute of Natural Sciences. "Frogs and toads are affected greatly by climatic and environmental changes, so they are an important source of information to understand past climates," he added.  The discovery took place at a depth of 44 meters during the drilling of a water well in San Pedro, 180 km north of Buenos Aires.  The researcher stressed that the paleontologists found "the bone of the humerus is 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 braids that include frogs and alagalam, have a special structure at the end of the humerus in the elbow joint.  "The find makes a huge contribution to paleontology in Argentina," said Federico Aniolan.
