Conodonts and Biostratigraphic Correlation
Annual Review of Earth and Planetary Sciences, 1986At its 1969 meeting, The Pander Society convened a symposium on conodont biostratigraphy that resulted in a volume (Sweet & Bergstrom 1971a) in which specialists systematically summarized the status of conodont-based biostratigraphy up to 1969. One function of such a volume is to direct attention to areas that need more work and to focus on conclusions

On the Affinities of Conodonts
1972Conodonts are phosphatic, denticulated structures in the average size range from 0.1 to 1 mm. They grew by the centrifugal accretion of lamellae. Conodonts are a homogeneous group. Basic interpretations must apply to all kinds of conodonts. Internal and outer morphologic features indicate that they were skeletal elements designed to lend a certain ...

Geological Society of America Bulletin, 1969
The known distribution of conodonts in the Cambrian of Europe, Asia, and North America is not uniform, but no major discrepancies in stratigraphic range of form species has been noted. The oldest reliably dated conodont known is a Hertzina species which is known in upper Middle Cambrian rocks in Nevada and Bornholm (Denmark).

Conodont Biostratigraphy of the Triassic
1970Conodonts have been described from Jurassic rocks in Japan and from Upper Cretaceous rocks in western Africa. However, both occurrences might also be interpreted as reworked faunas. Arguments in favor of the reported ages include independent interpretation of the age of the enclosing rock and apparent lack of source rocks for reworking.

Conodonts through time and space: Studies in conodont provincialism
1984A computerized file of approximately twenty thousand records of conodont occurrences was used in a quantitative study of conodont provincialism. Although biases in the fossil record, in specimen collection, and in data collection preclude any rigid statistical testing, study of quantitative measures of similarity between faunas, when combined with ...
