Stratigraphy
Stratigraphic resolution:bed
Stratigraphy comments: At the same place another transported nodule contained a fragmentary ammonite resembling Pictetia or Argonauticera. As the geologic structure is complicated in the eastern coastal area of Cape Soya, the original bed of MNH.145 has not yet been determined, although the existence of the Albian is suggested.
