Rhinconichthys

Rhinconichthys is an extinct genus of bony fish which existed during the Cenomanian stage of the Late Cretaceous.

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.

Description
Rhinconichthys was a medium-sized fish. R.uyenoi grew to around 3.4 - 4.5 m long, while R.purgatoriensis was much smaller, around 2 - 2.7 m long.
