Fig. 16 in The Perinate Skull of Byronosaurus (Troodontidae) with Observations on the Cranial Ontogeny of Paravian Theropods

Fig. 16. Lateral (A) and medial (B) views of an articulated prootic and exoccipital/opisthotic in a perinate Struthio camelus. Note the medial opening of the metotic fissure is divided—in contrast to the undivided metotic foramen of IGM 100/974.

Fig. 15 in The Perinate Skull of Byronosaurus (Troodontidae) with Observations on the Cranial Ontogeny of Paravian Theropods

Fig. 15. Horizontal slice (A) through the braincase of the holotype of Byronosaurus jaffei (IGM 100/983) (B) showing the presence of pneumatic cavity in the base of the paroccipital process. The cavity is associated with a pair of rostral foramina and is inferred to result from invasion of the paroccipital process by diverticula of a posterior tympanic sinus residing in the posterior tympanic recess. The pneumatic cavity in the paroccipital process is largely infilled with a mineral inclusion that renders as a bright white in the figure. The white, horizontal line through the braincase (B) shows the position of the slice (A). Rostral is to the left, dorsal to the top.
