In 1914, on the eve of the First World War, two human skeletons were discovered during basalt quarrying at Oberkassel, Bonn in Germany. With them were found a right mandible of a "wolf" and other animal bones. After the end of the First World War, in 1919 a full study was made of these remains. The mandible was recorded as ""Canis lupus", the wolf" and some of the other animal bones were assigned to it. The remains were then stored and forgotten for fifty years. In the late 1970s there was renewed interest in the Oberkassel remains and the mandible was re-examined and reclassified as belonging to a domesticated dog. The mitochondrial DNA sequence of the mandible was matched to "Canis lupus familiaris" – dog and falls within mDNA haplogroup C of dogs. The bodies were dated to 14,223 YBP. This implies that in Western Europe there were morphologically and genetically "modern" dogs in existence around 14,500 YBP.
