Although known from Mesozoic marine, fresh and brackish water deposits from North America, Europe, Africa and Asia, hybodont shark remains have been rarely reported from the Cretaceous formations of Kansas. Remains of hybodonts reported from outside Kansas consist of small teeth, distinctive cephalic hooks, dorsal fin spines, and occasionally even complete fish. Collections of micro-vertebrate remains in Kansas since 1999 have confirmed the presence of hybodontiformes in the Kiowa (Albian), Dakota (Cenomanian) and Carlile (Turonian) formations in three different counties in the state. These specimens have been assigned to the genus Meristodonoides Underwood and Cumbaa 2010, and add an important element to the known marine faunas of the Western Interior Sea during late Early Cretaceous and early Late Cretaceous time.
