FIGURE 26. 3D renderings of the intracranial cavities within the articulated braincase of Irritator challengeri (SMNS 58022). A, posterior view; B, ventral view; C, right anterolateral view. Colours reflect cavity identity, where green cavities are within the otic bones, purple cavities are within the basioccipital (boc), blue cavities are within the parabasisphenoid (pbsp), and yellow recesses are within the orbitosphenoid. Abbreviations: bsr, basisphenoid recess; osr, orbitosphenoid recess; otor, otoccipitical recess; pror, prootic recess; sor, supraoccipital recess.
