Coevolution of Tooth Crown Height and Diet in Oreodonts (Merycoidodontidae, Artiodactyla) Examined with Phylogenetically Independent Contrasts (2006, methodology): “Using similar phylogenetic methods, Williams and Kay (2001) found evidence for a better coevolutionary relationship of crown height and ecological factors related to diet (foraging height and percentage of grass) among modern rodents and ungulates, but found a weaker coevolutionary relationship of…”
Characterizing complex craniodental patterns related to feeding behaviour in ungulates: a multivariate approach (2002, background): “There is also a phylogenetic effect, since not all exclusive grasseaters are similar in their degree of hypsodonty (Janis, 1988; Williams & Kay, 2001): for example, the grazing warthog Phacochoerus aethiopicus has higher molar crowns than other more omnivorous or browsing suids but lower crowns…”
Evolution of hypsodonty in equids: testing a hypothesis of adaptation (2006, methodology): “Level of aridity, which promotes the presence of both grasses and exogenous grit, and potentially negatively affects the nutritive value of graze and browse, is less clearly linked (Williams and Kay 2001, but see Damuth and Fortelius 2001; Fortelius et al. 2002).”
Tracing the ecophysiology of ungulates and predator–prey relationships in an early Pleistocene large mammal community (2008, background): “…as stable-isotopes and trace-elements, as well as from the comparative study of their craniodental morphology, because several features of the skull, mandible and dentition are indicative of diet (see reviews in MacFadden, 2000; Williams and Kay, 2001; Mendoza et al., 2002; Palmqvist et al., 2003).”
Hypsodonty in ungulates: an adaptation for grass consumption or for foraging in open habitat? (2008, background): “The results presented here contradict those obtained by Williams & Kay (2001), who concluded that habitat and climate variables played no significant role in the development of hypsodont teeth.”
Notoungulata and Litopterna of the Early Miocene Chucal Fauna, Northern Chile (2011, background): “In modern mammals, hypsodonty is highly correlated with dietary preference and can be used to distinguish animals feeding on vegetation in open habitats (which have more hypsodont teeth) from those feeding in closed habitats (Janis, 1988, 1995; Williams & Kay, 2001; Janis et al., 2002).”
Mammalian dental function and wear: A review (2015, unknown): “Cheek teeth are usually considered high-crowned, or hypsodont , when the height of the enamel cap is greater than its anteroposterior length [102].”
The Morphophysiological Adaptations of Browsing and Grazing Mammals (2008, background): “…for example, the often quoted increased amount of grit adhering to grass forage is a conceptual cornerstone of many investigations on the hypsodont dentition of grazers (Fortelius 1985; Janis 1988; Janis and Fortelius 1988; Williams and Kay 2001), but has never been demonstrated quantitatively.”
Grit not grass: Concordant patterns of early origin of hypsodonty in Great Plains ungulates and Glires (2012, background): “First, the amount of soil or grit ingested during feeding may be a more important abrasive agent than grass phytoliths (Stirton, 1947; Janis, 1988; Williams and Kay, 2001; Janis et al., 2002a; Damuth and Janis, 2011).”
Hypsodonty in Pleistocene ground sloths (2006, background): “Recent work (Williams and Kay 2001) has made it clear that both fac− tors must figure strongly in discussions concerning the devel− opment of hypsodonty in several “epitherian” groups.”
Evidence for geographic variation in the diets of late Pleistocene and early Holocene Bison in North America, and differences from the diets of recent Bison (2007, background): “Much of the overlap in the mesowear data for these dietary categories is attributable to the fact that abrasion levels in diets are not only related to the intrinsic properties of the plants themselves, but also variable amounts of extrinsic grit (dust and sand) that is incidentally consumed along w”
