Species Bulla ambigua d'Orbigny 1842


Discussion / Comments:
Griffin & Nielsen (2008):
TYPE MATERIAL. The holotype is housed in the Typothèque of the Laboratoire de Paléontologie under catalogue number MNHN-R63174. REMARKS. The holotype is a very poor internal mould. Without further material with shell preserved, generic assignment can only be tentative. Due to general shell shape and a thickened columellar base this species is still regarded as belonging to Bulla Linnaeus, 1758 [type species Bulla ampulla Linnaeus, 1758]. The sediment is very atypical for the Plio-Pleistocene near Coquimbo. It seems that d’Orbigny’s material comes from an unknown locality of uncertain – presumably Miocene – age.
