Sorry, no etymologies found.
I would expect ear-bone evolution to involve developmental regulatory changes.
Otolith: a little ear-bone: granules or concretions found in an otocyst.
It is probable, too, that ear-bones vary somewhat in form and thickness in the same species; this is certainly true in the case of the ear-bone of fishes, of which I have many specimens, among which there are several varieties of form and size.
The ear-bone of the Balena Mystictus, the common whale of the coast, in my possession, measured, rather diagnoally over the thick convoluted part, is 5½ inches long; the greatest thickness is 3 inches and 3 tenths; the depth or height of the convoluted part is 3 inches; greatest height measured to the top of the thin convolution 4 inches and 4 tenths.
This conclusion is founded upon the probability, that this ear-bone and certain thick heavy ribs of a whale, often found in the miocene deposits, belonged to this species.
