Tooth size variation within fossil assemblages can be associated with intra-or interspecific
variation, functional, developmental, and geographical factors, and/or sexual dimorphism …

The extensive diversity in dental form across mammals and its strong relationship with
function provides insights into the diet, habitat, and behavior, of both extant and extinct taxa …

The dentition is an extremely important organ in mammals with variation in timing and
sequence of eruption, crown morphology, and tooth size enabling a range of behavioral …

Pachyrukhinae (Hegetotheriidae, Notoungulata) is a highly frequent clade in the Late
Miocene-Pliocene outcrops of southern South America. In Argentina, two genera have been …

Notoungulates, native South American fossil mammals, have been recently objective of
several palaeoecological studies. Ecomorphology and biomechanics of the masticatory …

Abstract Members of the Order Notoungulata are among the most diverse and common
mammals in South America during the Cenozoic. Several lineages within notoungulates (eg …

Both hypsodonty and proportion of enamel are important measures for reconstructing diets
and environments of fossil mammals. Classically, the first is calculated using crude …

The evolution of increased tooth crown height is considered to be an adaptation for coping
with excessive rates of dental wear associated with abrasive herbivorous diets, such as …

Abstract Protypotherium (Mammalia, Notoungulata, lnteratheriinae) is a well-known and very
diverse genus of extinct native ungulates of South America, widely distributed from southern …

In marsupial mammals and their extinct relatives—collectively, metatherians—only the last
