Early evidence of molariform hypsodonty in a Triassic stem-mammal
(Nature, 2019-12)
Hypsodonty, the occurrence of high-crowned teeth, is widespread among mammals with diets rich in abrasive material, such as plants or soil, because it increases the durability of dentitions against wear. Hypsodont postcanine ...
Teeth complexity, hypsodonty and body mass in Santacrucian (Early Miocene) notoungulates (Mammalia)
(Royal Society of Edinburgh, 2017-02)
Notoungulates, native South American fossil mammals, have been recently objective of several palaeoecological studies. Ecomorphology and biomechanics of the masticatory apparatus, together with micro and mesowear analyses ...
When xenarthrans had enamel: insights on the evolution of their hypsodonty and paleontological support for independent evolution in armadillos
(Springer, 2014-09)
All xenarthrans known to date are characterized by having permanent teeth that are both high crowned and open rooted, i.e., euhypsodont, and with a type of hypsodonty different from that of the rest of Placentalia: dentine ...
Third upper molar enlargement in sigmodontine rodents (Cricetidae): Morphological disparity and evolutionary convergence
(De Gruyter, 2020-05)
We studied the enlargement of the upper third molar (M3), with respect to the upper second molar in sigmodontine rodents, the largest subfamily of living cricetids. M3 is enlarged in extant and extinct members of at least ...
Dental eruption sequence and hypsodonty index of a Pleistocene macraucheniid from the Brazilian Intertropical Region
(Journal of Paleontology, 2018)
Paleoecological implications of dental mesowear and hypsodonty in fossil ungulates from Kanapoi
(Elsevier, 2020)
The Pliocene site of Kanapoi is key to our understanding of the environmental context of the earliest species of Australopithecus. Various approaches have been used to reconstruct the environments of this site, and here ...
