Abstract
Schuchmanoceras hamicarinatum, a new genus and species of Albian (Earl y Cretaceous) anisoceratid ammonite, is described on the basis of the unique combination of a ventral keel, distinctive sculpture, and aniso ceratid coiling. Its late Albian age is established by the contemporan eous ammonite species Anagaudryceras buddha, Pseudouhligella japonicum , Stoliczkaia notha, and Mesopuzosia colusaense.
