This photograph portrays the second most numerous shell adze from the Morhiss site. These adzes were manufactured from the interior columella obtained from large horse conch shells procured from the Texas Gulf Coast. Once the columella was procured a section of suitable length was removed by either the groove and snap technique or direct percussion. The cutting edge or bit was shaped by grinding and the proximal end was roughly prepared by light smoothing or grinding. Note the general morphological similarity of this shell adze type to the Guadalupe biface or adze. Again, the similarity may suggest a similar range of functions.
