In Depth
Rhinconichthys 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 from the USA were described, revealing to us that this fish genus potentially had a global distribution. Rhinconichthys is noted for the large hyomandibulae bones which would have allowed this to have had an incredibly wide gape, in turn allowing Rhinconichthys to filter large amounts of plankton from the sea water.
Rhinconichthys is related to the genera Bonnerichthys and Leedsichthys.
