The '''Yanigua Formation''' is a geologic formation in Dominican Republic. The lagoonal claystones and marls preserve fossils dating back to the Miocene period.<ref>[https://paleobiodb.org/classic/displayStrata?geological_group=&formation=Yanigua&group_formation_member=Yanigua Yanigua Formation] at Fossilworks.org</ref> The formation hosts Dominican amber.
