Abstract
Parametrs characteristic of Atrypa Histrix, collected from various localities of the Cerro Gordo Member of the Upper Devonian Lime Creek Formation, were measured as: 1) Length, 2) Width, 3) Thickness, 4) Number of growth lines, and 5) Number of plications. The consistency of data obtained within a sample location was tested against similar data representing the total population by means of F-tests. Results suggested that the three sample locations represented at least two statistically random sample populations. These statistical differences in the single biologic population may be alternately interpreted as: 1) the population differed prior to preservation, or 2) is attributed to post depositional changes at the sample locations. F-tests of the parameter ratios increased resolution sufficiently to suggest a single sample population statistically characteristic of the one biologic population.
