Abstract

A statistical analysis of twelve Coelophysis bauri skulls from Ghost Ranch has been attempted incorporating bivariate and principal components techniques to search for allometric characteristics and consistent variation that might be attributable to systematic differences in the sample. The expected allometric patterns were observed in the eigenvectors of the first three principal components. The sample size is too small for well-defined clusters in the principal component plots, but as it increases, the allometric equations are not expected to change significantly.
