 (kō′nə-dŏnt′, kŏn′ə-)
n.
1. Any of various small marine chordates of the group Conodonta of the Paleozoic Era and the Triassic Period, preserved primarily in the form of their conelike teeth.
2. A fossil tooth of this chordate. Conodonts are the most widespread Paleozoic microfossils and are important for biostratigraphic indexing.

Biological biozoning studies were thus based on conodont elements in the studied section's complete rock sequence.
Scientists know that conodont elements worked differently from the teeth of other animals: they are microscopic - about 2 to 0.2 mm long - and must have had paltry muscles to move them, with no jaws to which they could attach.
One sample taken from the Raisin River Formation yielded over 30 identifiable conodont elements representative of--Ozarkodina remscheidensis, O.
96067) that, fortunately, yielded 27 conodont elements, although most are broken and thermally altered to CAI 6.
Purnell of Leicester University puts to rest arguments about the function of the conodont elements. Although the fossils look like teeth, some paleontologists discounted the resemblance because they could find no signs of wear.
The rock samples with arthrodire bones from Voskresenskoye also include conodont elements characteristic of the Ozerkian--Khovanshchinian interval (lower uppermost Famennian) in Central Russia: Icriodus costatus (Thomas, 1949), Pandorinellina humulus (Rhodes, Austin & Druce, 1969), Pelekysgnathus aff.
Samples Sa-04-04 and Sa-04-5A represent the interval of mixed light indigenous conodont elements and brownish redeposited specimens.
The Lower Carboniferous (Upper Tournaisian) conodont elements were collected from a section located in the Pechora region (North Russia, Pechora Swell, N 65[degrees]4'21", E 56[degrees]43'13"), where the host rocks represent the Idzhid Formation (Figs 1, 2).
