Rhombichthys intoccabilis is an extinct clupeomorph described from the town of Ein Yabrud, in the West Bank. It lived during the Cenomanian age of the Late Cretaceous epoch.
The adults of R. intoccabilis had a very deep, scute-covered belly. In conjunction with the high, triangular dorsal fin, the belly gives the fish a rhombus-shaped body profile, hence the generic name. The juveniles, in contrast, had a far shallower belly, having a rounded profile.
