 Since the third molar (the wisdom tooth) is present and its dentin exposed—although only in a few places—the age of death is estimated to be about 20 to 30 years.Schoetensack concluded a relationship to modern man ("Homo sapiens") from the similarity of the dentition and put the lower jaw in the genus "Homo"—a view that is still being held unanimously by today's palaeo-anthropologists.He derived the authority to define a new species with the type-epithet heidelbergensis from the fact that the lower jaw—in contrast to modern humans—is missing its chin.
