The ammonite on view belongs to genus Choffaticeras HYATT 1903, family Tissotiidae. The age of the fossil is the middle part of the Early Turonian. It is from the Yirka Fm. in the Upper Galilee, a few km. northwest of the town of Carmiel, reportedly rescued from a roadcut under construction. This is a large adult specimen, with the body chamber forming most of the final whorl and the sutured phragmocone not well preserved. The large, flat keeled morphology with shallow umbilical region suggest affinity to C. luciae, but it is not possible to conclusively assign it to this species.

Mishash Formation, Zin field

This partially silicified block, likely collected in northeastern Sinai in the 1970s, contains large elevator-type rudist bivalves forming interlocked, reef-like structures. Early silicification preserved honeycomb-like magnesian calcite shell walls and associated nerineid gastropods with screw-like columellae, including clionid sponge borings. The assemblage resembles Turonian outcrops from eastern Sinai, such as the Praeradiolites lewyi lewyi beds at Gebel er-Risha and the Wata Formation at Gebel Minshera.
