Journal: Paleobiology
Published: 01 January 2007
Paleobiology (2007) 33 (1): 53–75.
DOI: https://doi.org/10.1666/06044.1
... for shape differences observed in hypsodont teeth, P4s of the archaic lagomorphs Russellagus and Hesperolagomys , which exhibit pronounced change with wear, and Ondatra lower incisors, which show minimal change with wear. Using this quantification, I generate theoretical curvature morphologies and describe...

Figure 10. Results of modeled wear compared with observed wear of actual teeth from test samples. A, C, E: graphs comparing numerical values; gray rectangle indicates range of measured values, bounded by the area of tooth occupation (λi represents the test specimen at its initial wear stage, λi + ηi represents the most advanced stage of wear). B, D, F, Illustrations comparing cumulative wear surface produced by modeled wear (left) with worn specimens from test samples (right; pikas only). A, Graph of values of x from modeled wear with measured range of values of the occlusal width for Russellagus P4. B, Cumulative wear surface of Russellagus P4. C, Graph of values of x from modeled wear with measured range of values of the occlusal width for Hesperolagomys P4. D, Cumulative wear surface of Hesperolagomys P4. E, Graph of values of x from modeled wear with measured range of values of the occlusal width for Ondatra lower incisor. F, Cumulative wear surface of Ondatra lower incisor

Figure 3. Hybrid tooth curvature morphospace. Theoretical curvature morphologies 1–29 and curvatures of Ondatra, Russellagus, and Hesperolagomys teeth plotted by relative curvature (r2/r1) and relative displacement (d/r1). The light-gray area is the morphospace included in this study. Theoretical morphologies are scaled and the center of the outer circle is located at the appropriate coordinates for each morphology. Three thick gray lines mark mathematical boundaries to morphologies
