Ozarkodinida is an extinct conodont order.[1][2] It is part of the clade Prioniodontida, also known as the "complex conodonts".

Name

[edit]

Ozarkodinida is named after the Ozark Mountains of Missouri, United States.

Elements

[edit]

The feeding apparatus of ozarkodinids is composed at the front of an axial Sa element, flanked by two groups of four close-set elongate Sb and Sc elements which were inclined obliquely inwards and forwards. Above these elements lay a pair of arched and inward pointing (makellate) M elements. Behind the S-M array lay transversely oriented and bilaterally opposed (pectiniform, i.e. comb-shaped) Pb and Pa elements.[3]
