Thousands of specimens of the enigmatic fossil Gluteus minimus (new genus, newt species) occur in a 5-centimeter-thick interval within the Maple Mill Shale and in equivalent deposits of the Devonian of eastern Iowa. They are roughly lenticular. bilobed fossils up to 11 millimeters in diamiter and 8 milllimeters thic. These objects consistently asymmetrical in the same direction. defy placement in any known higher taxon when their morphology. histology, and apatitic composition considered.

Mitrellataxis, a New Multielement Genus of Late Devonian Conodont
Small size and similar morphology of the elements allow tentative reconstruction of the apparatuses of Mitrellataxis species, a new multielement conodont genus characterized by small squat platform-cones (new term) and small cusplike elements.

Piezoelectric Property of Otoliths
Otoliths of two species of bony fishes have been found to be piezoelectric. Hence, in theory, they constitute a mechanism for depth perception or frequency analysis of sound waves, or both.
Skewness and kurtosis as criteria of normality in observed frequency distributions
ABSTRACT Moment measures are widely used to describe the properties of samples. The third and fourth moments, descriptors of skewness and kurtosis, may be used to test the hypothesis that the sample
