Over eighty feet of undisturbed sand and sedimentary rock had been deposited over this interesting ancestor. For subsequent centuries the slow eroding action of the Neckar river carved out the valley, before this famous human fragment was eventually exposed to modern view (Fig. 88). The jaw is heavy, massive, and chinless. It is apelike in character but the teeth are comparatively small and have the shortened roots
. Biology of the vertebrates : a comparative study of man and his animal allies. Vertebrates; Vertebrates -- Anatomy; Anatomy, Comparative. Man in the Making 23 Heidelberg, Germany. Over eighty feet of undisturbed sand and sedimentary rock had been deposited over this interesting ancestor. For subsequent centuries the slow eroding action of the Neckar river carved out the valley, before this famous human fragment was eventually exposed to modern view (Fig. 88). The jaw is heavy, massive, and chinless. It is apelike in character but the teeth are comparatively small and have the shortened roots and dilated crowns that distinguish human teeth. With our knowledge limited to these interesting features of the lower jaw it is difficult to tell what may have been Heidel- berg man's position with relation to other fossil men. b--. Fig. 87. Outline of the Heidel- berg jaw, contrasted with that of the chimpanzee and man. (After Boule.).
