Haughton kindly let me copy a sketch of the palate of the type in the British Museum, and I quote the following from his notes: "My interpretation of the palate is entirely different from that of Watson. All the easily visible by wetting the skull; there is no interpterygoid suture; but there is a small interpterygoid vacuity. The arrangement of the bones is very similar to that in the form I have called Arctognathus whaitsi. The sutures are all plainly visible as convolute lines—and different from the straight cracks which Watson has misinterpreted as sutures. The palate thus agrees with the Aelurosaurids in the separation of the pterygoids.
