New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes) Oct 1961

New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes)

School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleoichthyology.

Squirrelfishes ( " Holocentridae" of authors) are generalized forms in which evolutionary divergence of some mag nitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separate. at least since the middle Eocene.

A revised classification, based on available lines of …


Crustacean Gastroliths From The Jackson Eocene Of Louisiana May 1961

Crustacean Gastroliths From The Jackson Eocene Of Louisiana

School of Mines and Metallurgy Bulletins

Wechesia louisianae, n. sp., is described from upper Eocene beds at Montgomery, Louisiana. Second species of the genus, it extends the range of Wechesia Frizzell and Exline from Claiborne (middle) Eocene and validates the generic diagnosis.
