teeth are interpreted to be incompletely mineralized, non-functional
replacement teeth. The tooth histology is osteodont.
The jaw piece (Fig. 2A) measures approximately 31 cm in
maximum preserved length, which corresponds to the anteroposterior
axis of the jaw ramus. It is three-dimensional and
appears to be relatively uncrushed. One end has a dorsoventral
depth of approximately 8.5 cm, whereas the maximum dorsoventral
depth located near the other end of the jaw piece is 13.5 cm.
The dorsoventrally shallower side is considered to be the anterior
