Rimasuchus is an extinct genus of crocodile from the Miocene of Egypt and possibly Libya. Only one species - Rimasuchus lloydi - is currently known. It was previously thought to be a species of Crocodylus, but is now thought to be more closely related to the modern African dwarf crocodiles (Osteolaemus).


Fossil crocodiles from all over Africa and the Middle East of Miocene, Pliocene, and Pleistocene age were previously referred to R. lloydi. The majority are now known to be extinct forms of Crocodylus. The generic name "Rimasuchus" comes from the Latin words rima, meaning "crack" (referencing the East African rift valley),[1] which is ironic because Rimasuchus is not currently known from deposits in East Africa.
