“…Enamel microwear represents 1 such line of evidence (Townsend and Croft 2008), and incisor morphology might be another. Combined with studies of carbon isotopes (MacFadden and Shockey 1997) and potentially cheek tooth morphology (Evans et al 2007), the accuracy of dietary interpretations for caviomorph rodents might approach that currently available for ungulates (Janis 1995;Palmqvist et al 2003;Semprebon and Rivals 2007). Dietary data from caviomorph rodents also might prove useful for inferring diet in superficially rodent-like members of extinct clades, such as typothere notoungulates (Croft 1999;Reguero et al 2007).…”

“…A combination of sharp cusps and high relief was assigned a score of 0; a combination of rounded cusps and high relief was assigned a score of 1; a combination of rounded cusps and low relief was assigned a score of 2; a combination of blunt cusps and low relief was assigned a score of 3. An overall mesowear score for each sample was then calculated by averaging individual mesowear scores (see an example of application in Rivals et al, 2007b andRivals, 2007).…”

“…En algunos herbívoros se incrementa la dentición de corona alta o hipsodoncia a pesar de que los hábitos ramoneadores seguían dominando en una parte de los biomas terrestres norteamericanos. Esta dentición se da básicamente en ungulados endémicos de Norteamérica: antilocápridos, équidos y camélidos (Semprebon & Rivals, 2007;Wang et al, 1994). Un dato curioso es el bajo número de ungulados de pastoreo a pesar de una dramática pérdida de la vegetación C3.…”

“…Los carnívoros también fueron afectados, desaparecen un número importante de géneros arbóreos y trepadores (escansoriales); se extingue la Familia Barbourofelidae y se pierden varios miembros de los mustélidos. Sin embargo, los taxones menos afectados, fueron aquellos que pudieron extender su nicho ecológico al nuevo entorno ambiental: los taxones de dentición hipsodontos (incluyendo los mesodontos), fueron menos perturbados, al parecer esta adaptación dentaria les permitió ampliar el rango del nicho para el consumo tanto de pastoreo, como el ramoneo (Edwards et al, 2010;Semprebon & Rivals, 2007).…”
