I haven't learned Seder Kodshim before, and I understand there's no Talmud Yerushalmi on Seder Kodshim, but I saw in a bunch of places in maseches Temurah where Rashi quotes "loshon Yerushalmi" (search לשון ירושלמי on Sefaria, turned up ten instances in Temurah). It's always a different version of the gemarra than what appears in the Bavli.
Is this referring to the Talmud Yerushalmi? How did Rashi have a Yerushalmi on Kodshim, and we don't? Or is it just a different girsa in the Bavli that originated from Jerusalem? Or something else?
