A diminutive Pliocene guenon from Kanapoi, West Turkana, Kenya.
(Journal of human evolution, 2019-10)Although modern guenons are diverse and abundant in Africa, the fossil record of this group is surprisingly sparse. In 2012 the West Turkana Paleo Project team recovered two associated molar teeth of a small primate from ... -
Dental microwear in live, wild-trapped Alouatta palliata from Costa Rica.
(Am J Phys Anthropol, 1991-07)One problem with dental microwear analyses of museum material is that investigators can never be sure of the diets of the animals in question. An obvious solution to this problem is to work with live animals. Recent work ... -
Dietary inference from upper and lower molar morphology in platyrrhine primates.
(PLoS One, 2015)The correlation between diet and dental topography is of importance to paleontologists seeking to diagnose ecological adaptations in extinct taxa. Although the subject is well represented in the literature, few studies directly ... -
Mammalian molar complexity follows simple, predictable patterns.
(Proceedings of the National Academy of Sciences of the United States of America, 2021-01)Identifying developmental explanations for the evolution of complex structures like mammalian molars is fundamental to studying phenotypic variation. Previous study showed that a "morphogenetic gradient" of molar proportions ... -
Oldest known cranium of a juvenile New World monkey (Early Miocene, Patagonia, Argentina): implications for the taxonomy and the molar eruption pattern of early platyrrhines.
(J Hum Evol, 2014-09)A juvenile cranium of Homunculus patagonicus Ameghino, 1891a from the late Early Miocene of Santa Cruz Province (Argentina) provides the first evidence of developing cranial anatomy for any fossil platyrrhine. The specimen ... -
Smooth operator: The effects of different 3D mesh retriangulation protocols on the computation of Dirichlet normal energy.
(American journal of physical anthropology, 2017-05)Dirichlet normal energy (DNE) is a metric of surface topography that has been used to evaluate the relationship between the surface complexity of primate cheek teeth and dietary categories. This study examines the effects ... -
The effect of differences in methodology among some recent applications of shearing quotients.
(Am J Phys Anthropol, 2015-01)A shearing quotient (SQ) is a way of quantitatively representing the Phase I shearing edges on a molar tooth. Ordinary or phylogenetic least squares regression is fit to data on log molar length (independent variable) and ... -
The effect of high wear diets on the relative pulp volume of the lower molars.
(American journal of physical anthropology, 2021-04)<h4>Objectives</h4>One role of dental pulp is in the upkeep and maintenance of dentine. Under wear, odontoblasts in the pulp deposit tertiary dentine to ensure the sensitive internal dental tissues are not exposed and vulnerable ... -
Three-Dimensional Geometric Morphometric Analysis of Treeshrew (Scandentia) Lower Molars: Insight into Dental Variation and Systematics.
(Anatomical record (Hoboken, N.J. : 2007), 2019-07)Scandentia (treeshrews) is an order of small-bodied Indomalayan mammals generally agreed to be a member of Euarchonta with Primates and Dermoptera (colugos). However, intraordinal relationships among treeshrews are less ...
