Pseudaspidoceras is an ammonoid cephalopod included in the Acanthoceratidae that lived during the early Turonian stage of the Late Cretaceous.

Pseudaspidoceras has a high, rectangular whorl section. Ribs are almost absent, however tubercles are distinct. The shell itself is evolute, with all whorls exposed.

Now included in the Euomphaloceratinae, Pseudaspidoceras was previously seen as belonging to the Mammitinae from which is was removed.
