From theCambridge English Corpus Belemnites, bivalves, crinoid ossicles and wood remains are scattered throughout. From theCambridge English Corpus The ossicles function as an impedance transformer to provide sufficient force at the oval window to move the fluid which fills the cochlea in response to external acoustic vibrations. From theCambridge English Corpus As well as the local fauna, the mudstone also contains smaller debris: five-sided star-shaped crinoid ossicles, a few small belemnites, a possible echinoid spine impression and probable fish scales.
