o This is the paper which first proposed the reading JATZ’ for this logogram, based on the substitution of ja-tz’a as a pure syllabogram-only spelling (and also ja as an initial phonetic complement of the logogram).

o This proposal which is convincing and has now been completely accepted.

·    K2068 H1 is unusual in that it writes jatz’noom but with an underspelled -n- instead of an underspelled -m-. Usually, there’s a no and ma written, or only no without ma, hardly ever ma without no.

·    There’s little doubt that this glyph is JATZ’. But the relationship between this “hand holding a rock” / JATZ’ and the “hand holding an atlatl” (sometimes read JATZ’OOM) is complicated. See JATZ’OOM.

·    Zender-GFHaS cites these two as examples of ja-tz’a è jatz’ – substitutions for the logogram which enable the decipherment of the logogram’s reading.

·    MHD (2025-07-31) reads SCU Stela 1 C3 as tz’a-ja rather than ja-tz’a.
