FIG. 45 in Alcidedorbignya inopinata, a basal pantodont (Placentalia, Mammalia) from the early Palaeocene of Bolivia: anatomy, phylogeny and palaeobiology

FIG. 45. — CT-slices through the skull of MHNC 8399. The numbers for each illustrated slice refer to the position of the slice within the sequence of 1952 images (resolution binned images, voxel size = 0.024 mm). Top of the skull toward the top, right side of the skull toward the left. Note that the slices are slightly oblique relative to the sagittal plane, and therefore the two sides of the skull are not exactly symmetrical on the images. Abbreviations: asc, anterior semicircular canal; atf, anterior temporal foramen; ats, sulcus for the auditory (Eustachian) tube; coc, cochlear canal; cpevs, sulcus of the capsuloparietal emissary vein; er, epitympanic recess; fai, foramen acusticum inferius; fo, foramen ovale;fs, facial sulcus; frsu, foramen for the superior ramus of the stapedial artery; lsc, lateral semicircular canal; mtf, median temporal foramen; ots, orbitotemporal sulcus;pgf, postglenoid foramen;pr, promontory; prtf, posterior temporal foramen;psf, petrosquamosal fossa; ptc, posttemporal canal; saf, subarcuate fossa; scc, secondary common crus; sgc, sagittal crest; smf, suprameatal fossa; stf, stapedial fossa; ves, vestibule.
