Discussion.
A single fragment of a triphorid species is present in the Santa Maria assemblages. It is missing the protoconch and neanic whorls so that the order of appearance of the spiral cords is difficult to assess. However, it seems that the middle cord might be the last to appear. Further classification is not possible.
Distribution.
