    2. Background Conodonts. Conodonts are skeletal remains that were part of the feeding apparatus of extinct, elongated, bilaterally symmetrical soft-bodied animals that may be members of the phylum Chordata (Donoghue et al., ).These remains are composed of apatite with the general formula Ca 5 Na (PO 4) (CO 3) F (H 2 O) (Pietzner et al., ).Cited by: Apparatus of the Pennsylvanian Conodont genus Neognathodus. by Merrill, Glen K; Von Bitter, Peter H The larva and pupa of the caddisfly genus Setodes in North America (Trichoptera: Leptoceridae) p. 10 Topics: Royal Ontario Museum of Archaeology, Books, Printing, Illumination of books and manuscripts, ROM Publications.

The conodont genera found there commonly include Idiognathodus, Idiognathoides, Neognathodus, Adetognathus, Hindeodus, Diplognathodus, Idioprioniodus and, in recent addition to those, the herein presented Ellisonia, Gondolella and Ubinates. These associations are useful to the correlations with North American Pennsylvanian strata, mainly.

Ecologic controls that effected conodont distribution are believed to have been salinity, energy, pH, and possibly biologic antagonism.

Neognathodus is the most useful conodont genus for biostratigraphy in these rocks. Four zones and subzones are based on species of this genus and it has permitted relatively precise interregional correlations.

We studied details of the conodont assemblages in two deep-water sections spanning the mid-Carboniferous boundary at Guizhou, South China.

Forty-six species/subspecies were identified belonging to 13 genera, including Lochriea, Gnathodus, Declinognathodus, Idiognathoides, Idiognathodus, Neognathodus, Neolochriea, Swadelina, ‘Streptognathodusii’, Cavusgnathus, Cited by: 2.

the zone of Neognathodus uralicus; the zone of Declinognathodus donetzianus; The top of the Kasimovian, the third stage in the Pennsylvanian, is close to the first appearance of the conodont Streptognathodus zethus. The Kasimovian is subdivided into three conodont biozones: the zone of Idiognathodus toretzianus; the zone of Idiognathodus sagittatus.

The conodont genus Neognathodus becomes extinct at the end of Desmoinesian time. It is present below the top bench but is absent from the youngest bench of the West Franklin, thus supporting placement of the series boundary below the top bench. Later Mississippian (upper Chesterian) to Early Pennsylvanian (lower Morrowan) conodont faunas were recovered from limestones and calcareous mudstones of the Alaska Bench Formation in central Montana.

Four new species of the conodont genus Hindeodus, Hindeodus eurypyge sp. nov., Hindeodus inflatus sp. nov., Hindeodus sp. nov. A and Hindeodus sp.
