Data from: Testing a developmental model in the fossil record: molar proportions in South American ungulates

open access: yes, 2011
A developmental model, based upon murine rodents, has been proposed by Kavanagh et al. (2007) to explain lower molar proportions in mammals. We produce a clade-wide macroevolutionary test of the model using the dental evolutionary trends in a unique ...

(Mammalia, Notoungulata, Mesotheriidae) from the Early-Middle Pleistocene of Buenos Aires Province, Argentina

open access: yes, 2022
We report systematic conclusions based on critical analyses of previous taxon diagnoses and systematic revisions of the Early-Middle Pleistocene mesotheriine notoungulate Mesotherium cristatum, from Buenos Aires province, Argentina. Mesotherium cristatum

Teeth complexity, hypsodonty and body mass in Santacrucian (Early Miocene) notoungulates (Mammalia) [PDF]

open access: yes, 2019
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 on tooth enamel, were applied in

First digital cranial endocasts of late oligocene notohippidae (Notoungulata): implications for endemic south american ungulates brain evolution [PDF]

open access: yes, 2015
Notohippidae were middle-sized toxodonts recorded from the Eocene to the early Miocene. We provide the first description of the cranial endocasts of Rhynchippus equinus and Eurygenium latirostris based on three-dimensional reconstructions extracted from ...

Phylogenetic revision of the South American notopithecines (Mammalia: Notoungulata) [PDF]

open access: yes, 2016
A phylogenetic analysis of all Eocene taxa assigned to Notopithecinae has been conducted, evaluating relationships amongst notopithecines, basal interatheriids and Interatheriinae. Other groups of native ungulates were also included.

Updated synthesis of South American Mesotheriidae (Notoungulata) with emphasis on west-central Argentina [PDF]

open access: yes, 2018
Doctor Claude Guérin dedicated many years of his research to fossil rhinoceroses, but also to some of the interesting mammals that evolved in South America.
