“…However, in durophagous animals it is also important to maintain functional tooth sites, which should reduce the rate of tooth replacement (Dalrymple, 1979). This strategy of reducing the rate of tooth replacement to prolong individual tooth function should constrain tooth morphology, favoring tooth morphologies that will be less likely to break.…”

“…The first teeth are peg-like, and the posterior ones have a broad base. These have been variously described as "subpleurodont" (Dalrymple 1979), "subacrodont or acrodont" (McLean 1974), "molariform" (Estes and Williams 1984;Schwenk 2000), or "amblyodont" (Hoffstetter 1944;Rage 1987). However, they clearly constitute a modified type of pleurodont dentition with replacement, albeit at a reduced rate (Edmund 1969;Müller 2004).…”

“…Some dietary strategies seem to promote strong adaptive modifications in the skull and in the teeth. Lizard species that consume hard food items (durophagy), such as shelled molluscs, tend to form amblyodont teeth at the back of the tooth row (Lönnberg 1903;Peyer 1929;Dalrymple 1979;Rieppel 1979;Edmund 1969;Estes and Williams 1984;Schwenk 2000). Keeping to this theme, Müller (2004) has thoroughly discussed the functional interpretation of the peculiar anatomy of Dracaenosaurus croizeti.…”

“…Also, many modern and fossil taxa are know to have multiple cusps that superficially resemble mammalian teeth and may have served in insectivory or even herbivory (Clark et al 1989;Wu and Sues 1996;Larsson and Sidor 1999;Buckley et al 2000;Nydam et al 2000;Pol 2003;Osi et al 2007). This diversity of cusp morphologies clearly shows some selective pressure for enhancing the use of teeth on food processing, as many modern taxa with more complex crown morphologies (such as Dracaena and Tupinambis) teeth have been observed using these teeth for molar-like purposes (Dalrymple 1979).…”
