Abstract

"Otoliths are calcareous structures occurring in the auditory labyrinths of teleost (bony) fishes. Three pairs of these earstones normally are found: the sagitta, in the sacculus; the asteriscus, in the lagena; and the lapillus in the utriculus. In fishes other than the Order cypriniformes (carp, catfishes, and related forms), the sagitta is the largest otolith, and it may be used in taxonomic and other studies. Fossil earstones of cuskeels (Family Ophidiiae-Brotulidae), constituting the Preophidion complex, occur in relative abundance at various levels in the Claiborne, Jackson, and Vicksburg groups of the Lower Tertiary on the Gulf Coast. The present study was undertaken in order to separate and define the taxonomic units making up the complex"--Abstract, Page ii.
