Recent discoveries in southern France and northern Spain suggest that
the morphology of titanosaurian teeth shows much greater variations
that previously thought. It is suggested that the different
morphotypes are informative at specific or generic level and that
titanosaurian genera may indeed be recognized by their isolated teeth.
It is also confirmed that juvenile titanosaurian teeth have a rather
uniform, cylindrical morphology. Four different morphotypes are
described for the Ibero-Armorican Island in the Late Cretaceous.
