Material and dimensions .—See Table 2 . Description .—The general shape is rounded to quadratic in the anterior portion and strongly tapering posteriorly. Thus, the shape may resemble a hook. The anteromedial edge is a small hump and placed closely to the anterior margin. The antero− and posterolateral edges are angular and prominent.
