Hoploscaphites is an extinct ammonite genus from the Upper Cretaceous, included in the family Scaphitidae. It is considered by some to be a subgenus of Scaphites. Like Scaphites the shell of Hoploscaphites is involute with the final whorl projecting forward and curved back on itself. Shells vary from compressed to inflated with convex sides. Tubercles normally present may be sparse or absent.
Fossils of Hoploscaphites have been found in Antarctica, Austria, Belgium, Bulgaria, Canada (Alberta, Saskatchewan), Chile, Denmark, France, Germany, Greenland, India, the Netherlands, Turkmenistan, Ukraine and the United States (Arkansas, Colorado, Delaware, Kansas, New Jersey, New Mexico, North Dakota, South Dakota, Texas, Wyoming).
