Rhinconichthys is an extinct genus of bony fish which existed during the upper Cretaceous period.
Along with its close cousins the great-white-shark-sized or larger Bonnerichthys and the immense Leedsichthys, Rhinconichthys forms a line of giant filter-feeding bony pachycormid fish that swam the Jurassic and Cretaceous seas for over 100 million years.
