Rhinconichthys

Name: Rhinconichthys.
Phonetic: Rin-kon-ik-fiss.
Named By: Matt Friedman,‭ ‬Kenshu Shimada,‭ ‬Larry D.‭ ‬Martin,‭ ‬Michael J.‭ ‬Everhart,‭ ‬Jeff Liston,‭ ‬Anthony Maltese‭ & ‬Michael Triebold‭ ‬-‭ ‬2010.
Classification: Chordata,‭ ‬Actinopterygii,‭ ‬Pachycormiformes,‭ ‬Pachycormidae.
Species: R.‭ ‬taylori‭ ‬,‭ ‬R.‭ ‬purgatoirensis,‭ ‬R.‭ ‬uyenoi.
Diet: Filter feeder.
Size: R.‭ ‬purgatoirensis about‭ ‬2‭ ‬-‭ ‬2.7‭ ‬meters long.‭ ‬R.‭ ‬uyenoi.‭ ‬about‭ ‬3.4-4.5‭ ‬meters long.
Known locations: England.‭ ‬Japan‭ ‬-‭ ‬Mikasa Formation.‭ ‬USA,‭ ‬Colorado‭ ‬-‭ ‬Carlile Shale.
Time period: Turonian of the Cretaceous.
Fossil representation: Partial remains of several individuals.

       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.
