Examples
-
a common mammalian bone called the stylohyal bone physically connects the larynx to the ear
Scientific American 2010
-
The stylohyal does not unite with the rest of the bone until after puberty, and in some skulls never at all.
-
Its proximal part (tympanohyal) is ensheathed by the vaginal process of the tympanic portion, while its distal part (stylohyal) gives attachment to the stylohyoid and stylomandibular ligaments, and to the Styloglossus, Stylohyoideus, and Stylopharyngeus muscles.
-
The styloid process is developed from the proximal part of the cartilage of the second branchial or hyoid arch by two centers: one for the proximal part, the tympanohyal, appears before birth; the other, comprising the rest of the process, is named the stylohyal, and does not appear until after birth.
-
The stylohyal (s.h.), epihyal (e.h.), and ceratohyal (c.h.) form the anterior cornu of the hyoid.
-
The right, great cornu is shown extending backwards from the body of the Hyoid and terminating beneath the letters Ep.Fig. 40 -- Extracranial portion of hyoidean apparatus of Dog, front views sh, stylohyal; eh, epihyal; ch, ceratohyal (these three constitute the "anterior cornu"); bh, basihyal, or "body" of hyoid; th, thyrohyal, or "posterior cornu."
The Common Frog 1874
-
Veselka et al. 1 found that bats that use the larynx for producing the echolocating ultrasound have a stylohyal bone that connects the larynx to the auditory bulla.

-
In laryngeally echolocating bats, the proximal end of the stylohyal bone directly articulates with the tympanic bone and is often fused with it.

-
In this non-echolocating species, the stylohyal passes interior to the bone surrounding the eardrum, without contacting it.

I propose that the stylohyal bone is used for heterodyne detection of Doppler-shifted echoes.
