Romaniceras is a genus of early Upper Cretaceous ammonites (Cephalopoda, Ammonoidea), removed from the Acanthoceratinae to the Euomphaloceratinae.
The shell is rather evolute, whorl section circular to oval. Differs from Acanthoceras in having 9 or 11 rows of tubercles, of which the ventrolateral may be clavate {i.e. elongate). Ribs are strong and fairly close spaced.
