Comparisons of ink nose prints of cows and sheep, conducted for the Wells County Fair (Indiana) each summer since 1985, suggests that the relative sizes, shapes, alignments, and arrangements of the ridge units on the noses of cows and sheep are unique and permanent and may lead to a subsequent focus on human friction ridge evaluation.
Abstract
Experience gained comparing ink nose prints of cows and sheeps has facilitated understanding of David R. Ashbaugh's concepts of ridgeology and suggests that ridge units along the ridges in human latent and ink prints should be evaluated. Ashbaugh maintains that it is because of the plethora of genetic and physical variances during friction ridge formation that no two areas of friction skin ever will be found to be the same. Illustrations are included to provide an example of the principles of ridgeology and to highlight the unique arrangements and shapes of ridge units. 15 figures and 10 references
