- 1979, Michael Robert House, The Origin of Major Invertebrate Groups, page 235:
- The orthide billingsellaceans with their strophic hinge lines, deltidiodont dentition and invariably calcareous shells, comprise two families which, although morphologically similar, have a fundamentally different style of shell secretion, reflected in their various descendants.
- 2001, David Harper, Rong Jia-Yu, “Palaeozoic brachiopod extinctions, survival and recovery”, in Geological Journal, volume 36, page 317:
- The deltidiodont morphology did not survive the end-Permian extinctions; the modern articulated brachiopod fauna is dominated by cyrtomatodonts with crurae and loops.
Noun edit
