Teeth and part of a jawbone excavated in the cave in 1981 were dated to 230,000 years ago. The bone is from a Neanderthal boy approximately eleven years old. The teeth show evidence of enlarged pulp cavities and short roots, which is characteristic of Neanderthals. Although it is not unique to them, it is one of the reasons that the species was identified as Neanderthal.
