There is a sub-category of Nodena Points known as the Nodena Banks Variety. These points are distinguished from the larger Nodena group by having flat bases (or proximal ends). The methods of manufacture are identical to the larger Nodena Point group, and they are found within the same geographical and temporal ranges.
