Rhinconichthys is an extinct genus of bony fish which existed during the Cenomanian stage of the Late Cretaceous.[2]

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

[edit]

Rhinconichthys was a medium-sized fish. R.uyenoi grew to around 3.4–4.5 metres (11–15 ft) long, while R.purgatoriensis was much smaller, around 2–2.7 metres (6.6–8.9 ft) long.[1]
