| Summary |
"The need for the study of microfossils such as foraminifera, conodonts, and otoliths as stratigraphic tools has been well established. However, disarticulated parts such as otoliths and conodonts cannot be effectively used unless they can be recognized. Otoliths, although somewhat unrecognized in the geological record, are far more abundant than articulated skeletons (Frizzell, 1965, p. 86). Therefore, much investigation is being conducted to reveal the origin, function, morphology, and usefulness of the otoliths of fishes. In this investigation, the asteriscus, well developed only in Ostariophysins (of which the carp is a member), is studied for morphology. New tentative terms are used to name previously undesignated parts. The origin and development of otoliths has been studied and it is shown that the nuclei of otoliths originate as a mass of individual crystals rather than a single tiny crystal. Finally, the possible methods of preservation of carp otoliths are discussed"--Abstract, leaf ii. |
