The deep mandible of Tseajaia

The original reconstruction of Tseajaia (Vaughn 1964, Moss 1972) has a problem (Fig. 1). The mandible is too deep to fit inside the jaws. But, no worries! It’s a quick fix.

Figure 1. The original reconstruction of the Tseajaia skull and closed mandibles did not take into account the great depth of the anterior mandible. That is remedied here.
