"Gillicus arcuatus" was a relatively small, 2-meter long ichthyodectid fish that lived in the Western Interior Seaway, in what is now central North America, during the Late Cretaceous. Like its larger relative, "Ichthyodectes ctenodon", "G. arcuatus" had numerous small teeth lining its jaws, and ate smaller fish by sucking them into its mouth.
