In mammals there are:
- Processus styloideus ossis temporalis at the pars petrosa of the temporal bone ( fossa retromandibularis ): It merges into the ligamentum stylohyoidum . This band of connective tissue in turn ends at the hyoid bone ( os hyoideum ) and is used to suspend it. An excessively long styloid process leads to the so-called Eagle syndrome ( stylohyoid syndrome ) .
- Processus styloideus radii : blunt, at the lower lateral end of the spoke ( radius )
- Ulnar styloid : dull, at the lower end of the ulna ( ulna ): it is at the little finger side above the wrist more or less clearly and approach to the ligamentum collaterale carpi ulna .
