Abstract: This paper presents insights into the variety and variability in skull shapes of crocodiles using both traditional and nontraditional measurements within a landmark analysis. Using 159 adult crania of all 23 crocodilian species from the collections of five European museums, we found that the relationship between total skull width and length does not account for the majority of the variation between crocodilian species. We identified measurements between the orbit and premaxillary notch, explaining 90% of the variance, the distance from the orbit to the 5th maxillary tooth, and Kälin's number 12 (1933) as main focal areas for species differentiation. These measurements usefully define the shape of the crocodilian skull, differentiate between species with good precision, and allow reasonable inferences about function.
