Stratigraphy comments: This is restricted to Unit 10, of the 10 units into which the Lopez de Bertodano FM was divided, and it contains the K-T boundary, though it is ill-defined. This collection is only for Unit 10 taxa collected ABOVE the "K/T transition interval", and so is clearly Danian in age.
