The Matmor Formation is a geologic formation of up to 100 metres (330 ft) thick, that is exposed in Hamakhtesh Hagadol in southern Israel. The Matmor Formation contains fossils from a Jurassic equatorial shallow marine environment. Bivalves, gastropods, sponges, corals, echinoderms, and sclerobionts are present in the Matmor Formation to various degrees (Wilson et al., 2010). The stratigraphy of the Matmor Formation consists of alternating layers of limestone and marl (Hirsch and Roded, 1996).
