·     I’m not aware of any inscriptions in which this variant occurs.

·     This element is no longer considered to be a syllabogram. It only occurs to write ch’ok in the phrase u-ch’ok k’aba’, and always in combination with the so-called “row of teeth” variant of ko (also no longer considered to be a syllabogram). Instead that fixed combination of “goggle eyes” above and “row of teeth” below is now considered to be CH’OK (i.e. a logogram) – see CH’OK for more information.
