... neurodontiform elements grouped within the Chirognathidae and Coleodontidae, form a prominent component of the Winneshiek Lagerstätte. Conodont elements from the fauna commonly preserve complete basal structures, a rarity for most conodont preservations ( Figs. 2A and 2B ). Conodont hard tissue structure...

... Chirognathus and other neurodontiform elements (e.g., Curtognathus and Erismodus ). The taxonomy of Chirognathus is not well known ( Sweet, 1982 ), but its apparatus is most likely similar to that of Erismodus ( Sweet, 1988 ).
