Maraisaurus parvus K210 X 1. A. Parasagittal view reconstructed from serial sections. B. Sagittal view The pterygoid dorsally bears a low septum. Posteriorly, above the inter- pterygoid vacuity, the paired parasagitally situated septa enclose a trough, but anteriorly these meet in the median line to form a single median septum. For a short distance the upper edge of this septum is forked and these would apparently clasp the lower edge of the septosphenoid when ossified. Anteriorly the pterygoids do not extend in between the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
