Again, at Arcy-sur-Cure three skulls have been discovered placed closely together, and with them a flint knife in a layer superposed upon an Aurignacian industry. The Placard type of burial of the head only is shown again in the Azilian stage at Ofnet, Bavaria. The uncertainty regarding the racial affinity of the men of Magdalenian culture has now been entirely removed by the discovery, in February, 1914, of two skeletons at Obercassel, near Bonn, the first instance of complete human skeletons of Quaternary age being found in Germany.(12) As reported by Verworn,(13) the skeletons lay little more than a yard apart; they were covered by great slabs of basalt, and lay in a deposit of loam deeply tinged with red. This red coloring matter, which extended completely over the skeletons and surrounding stones, indicates that it was a ceremonial burial similar to that practised by the Aurignacian Crô-Magnons. Along with the skeletons were found bones of animals and several specimens of finely carved bone, but no flint implements of any kind. The bone implements include a finely polished 'lissoir' of beautiful workmanship, placed beneath the head of one of the skeletons; the handle is carved into a small head of some animal resembling a marten; the sides show the notched decoration so typical of the French Magdalenian. The second specimen of carved bone is one of the small, flat, narrow horse-heads, engraved on both sides, such as are found at Laugerie Basse and in the Pyrenees. One of the skeletons is of a woman about twenty years of age, and, as is usual in young female skeletons, it exhibits the racial characters in a much less marked degree than the male skeleton, which belongs to a man of between forty and fifty years; the cephalic index is 70 per cent; the supraorbital ridges are well developed, and the orbits are distinctly rectangular; the limb bones indicate a body about 155 cm., or 5 feet 1 inch, in height.
