Here is what has been exposed so far. The entire rear left portion of the skull is very well preserved and the elements are freeing nicely from the sandstone matrix. Anterior (forward) is to the left. Abbreviations are as follows: f, frontal; ltf, lateral temporal fenestra; na, nasal; orb, orbit; po, postorbital; q, quadrate; qj, quadratojugal; and sq, squamosal.
We'll keep following as preparation continues. We are pretty excited about this skull as it appears to be relatively pristine.
