The skull at the picture shows us an ancient dog skull that is 33,000 years old. This skull was found in Siberia at Altay Mountains. The earliest recorded dog skull was 14,000 year old, but now after 3 radiocarbon dating examinations it is proved that this it is the earliest one. As scientists say wolves evolve into dogs every 50-100 years and that it would be a very important find ,if they found an ancient wolf turning into dog. Fortunately they founded him. The skull is from a wolf that died while he was evolving into a dog. But they can not learn the cause of his death. The reason the skull kept being in a good shape is because of the cold temperature and non-acidic soil of the cave.
