Vascoceratidae

The Vascocertidae, named by Spath (1925) is family of Upper Cretaceous ammonites in the Superfamily Acanthocerataceae characterized by shells that are either smooth or bluntly tuberculate, or have sparse, coarse ribs. Sutural elements are shallow, irregular, and slightly indented, or deep and very indented. Whorl section and degree of involution vary, even within species.

The Vascoceratidae is a short lived family restricted to the early and middle Turonian stage. Its duration, no more than a few million years. They are derived from the Acanthoceratidae and are the predecessors of the Tissotiidae, which in turn gave rise to the Coilopoceratidae; all taking place in a short time span in the Turonian.
