“…The Poisson's ratio used in the analyses was 0.30, which is the same as in human teeth (Rees and Hammadeh 2004). The density-2800 kilograms per cubic meter (kg/m 3 )-assigned to the models is that of human enamel (Manly et al 1939). Finally, the model's yielding point (or failure stress) indicates the breaking point of the material, and sets an upper level for the structure's performance.…”

Although the herbivorous dinosaur Stegosaurus (Ornithischia, Stegosauridae) is a well-described Late Jurassic taxon, little is known about the feeding habits and biomechanics of its homodont dentition. The presence of a rhamphotheca has been suggested, but it is still unknown how much such structure would have participated in the foraging behaviour of Stegosaurus. To better understand the feeding mechanism of this taxon, three-dimensional models of a Stegosaurus tooth were created, using the software ZBrush Ò . One model was simple and lacked serrations, whereas the other model included serrations. Those models were then transferred to the software Strand7 Ò , where finite element analyses took place. The models were given material properties of enamel, based on studies done with crocodilian and mammalian teeth. In addition to that, bite forces were calculated for Stegosaurus, based on skull proportions. The results show little difference between the force distributions on the serrated and non-serrated models, indicating an efficient mechanism of stress dissipation that avoids high stresses being transferred to the jaw bones during biting. Digital plant models were also created to test the calculated bite forces in Stegosaurus, which suggests this animal was capable of biting through smaller branches. Computer modelling and analyses provide additional information about feeding habits and plant preferences for Stegosaurus, and can be adapted for studying other comparable herbivorous taxa.

“…In brief, dentin was ground from the tooth crowns using burs, the enamel caps were crushed in a percussion mortar and then powdered as above. Residual dentin was removed by centrifugation in a bromoform/acetone mixture, specific gravity 2.80 [21]. The powder was finally washed in ethanol and air-dried.…”
