Deflandridium stellatum
Deflandrinium stellatum Nagy, 1969
Fensome et al., 1990, stated: "Although Nagy (1969) listed a holotype, she did not state which of her illustrations represented that specimen. Nagy (1969) in her plate captions designated figs.3-4,6 as generotypes; however, these three illustrations do not appear to represent the same specimen."
Based on this, Fensome et al., 1990, considered the specific name Deflandridium stellatum to be not validly published. This is incorrect. The specific name Deflandridium stellatum was validly published by Nagy (1969), since she did designate a holotype, even though she did not state which of her illustrations represented that specimen.
Holotype: designated, but not identified in illustrations
Age: Late Miocene
