was first named in 2010, from fossils that had been discovered in
England. Then in 2016 a description of two new species, R.
uyenoi from Japan and R. purgatoirensis
described, revealing to us that this fish genus potentially had a
global distribution. Rhinconichthys is noted for
hyomandibulae bones which would have allowed this to have had an
incredibly wide gape, in turn allowing Rhinconichthys
large amounts of plankton from the sea water.
Rhinconichthys is related to the genera Bonnerichthys and Leedsichthys.
