Chelonate cuneiform

Is there a particularly erudite captain who could translate those marks on the turtle’s shell?[li]
I swung by there again just now to get a clear screenshot, and nothing was entirely identical when I compared it to the first list google gave me. More damningly the shell only bears like 2-3 main glyphs that are repeated, so-it’s probably just for atmosphere? The two sides don’t mirror each other (probably) and there aren’t enough lines sandwiched between two other lines to be like the angler crabs, and I’m not sure if there’s much overlap between Irem and the first city beyond geographic proximity (and the chelonites, whoever they were.) Any thoughts? I also got a screenshot of Codex but it’s too much like my handwriting to be legible.
