    Comments

    Trigonostoma elizabethae was named by Olsson & Petit (1964).  Axel Olsson was an oil geologist who published in paleontology while Richard "Dick" Petit who recently passed away was a natural history bookseller who became the foremost authority on the family Cancellariidae.  In describing T. elizabethae they noted that the shell has a nodose shoulder with two very nodose primary cords on the body whorl in addition to less nodose secondary cords.
