The stylids on the buccal side are protostylid, an inconstant ectostylid and a ptychostylid, while on the lingual aspect there are the metastylid and the entostylid. On unworn teeth, a crest, the paralophid, can be distinguished extending from the protoconid to the protostylid in the anterolingual corner. On the lingual aspect there are two prominent internal depressions or invaginations, the metaflexid anteriorly and the entoflexid posteriorly. The metastylid and the metaconid are two rounded formations joined by a narrow isthmus, giving the appearance of a bow tie and forming the so-called 'double knot'. SUMMARY OF THE CHARACTERISTICS OF HIPPARION TEETH Based on Gromova's detailed description (1952, pp. 70-6), the following characteristic features are 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.
