Der Unterkiefer des Homo Heidelbergensis: Aus den Sanden von Mauer bei Heidelberg

A well-preserved fossil lower jaw recovered from fluvial sand deposits near Mauer is described with precise stratigraphic and field-context information. The geological section reconstructs the local sedimentary sequence and situates the specimen within older Quaternary deposits. The mandibular anatomy is documented through detailed morphological description, measurements, radiographs, and plaster casts, and is compared systematically with other fossil and recent jaws. Plates illustrate the specimen and comparative material. The author interprets the anatomical features in relation to primate and human skeletal morphology, discussing variation, possible affinities, and implications for understanding dental and mandibular development.
