The Elrhaz Formation is a geological formation in Niger, central Africa.
Its strata date back to the Early Cretaceous (late Aptian-early Albian stages, about 112 million years ago). Dinosaur remains are among the fossils that have been recovered from the formation, alongside those of multiple species of crocodyliformes.
