The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
TLDR
A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).
Functional morphology of the forelimb of Tupaiids (Mammalia, Scandentia) and its phylogenetic implications
  • E. Sargis
  • Biology
    Journal of morphology
  • 1 July 2002
TLDR
Compared to the forelimb character states of tupaiines, those of Ptilocercus are more similar to those of other archontans and it is proposed that the attributes of theForelimb of PtILocERCus are primitive for the Tupaiidae.
New Paleocene skeletons and the relationship of plesiadapiforms to crown-clade primates
TLDR
The results, based on the fossil record, unambiguously place plesiadapiforms with Euprimates and indicate that the divergence of Primates (sensu lato) from other euarchontans likely occurred before or just after the Cretaceous/Tertiary boundary (65 Mya), notably later than logistical model and molecular estimates.
Body mass in Cercopithecidae (Primates, Mammalia) : Estimation and scaling in extinct and extant taxa
TLDR
A comparison of Estimation Accuracy with Previous Studies and the Applications of Paleobiological Applications of the authors' Estimates shows that sex Dimorphism and Evolution of Cercopithecid Mass through Time through Time are major themes.
Model-based analysis of postcranial osteology of marsupials from the Palaeocene of Itaboraí (Brazil) and the phylogenetics and biogeography of Metatheria
TLDR
Over 130 specimens of metatherian bones from the Palaeocene Itaborai fissures of Brazil are described and analyzed from a functional-adaptive perspective, in order to understand the adaptations of species they represent, obtain taxonomic properties of the species taxa they represent; and estimate their phylogeny within the Metatheria.
A New Genus of African Monkey, Rungwecebus: Morphology, Ecology, and Molecular Phylogenetics
TLDR
Detailed molecular phylogenetic analyses of this specimen demonstrate that the genus Lophocebus is diphyletic, and provide a description of a new genus of African monkey and of the only preserved specimen of this primate.
Functional morphology of the hindlimb of tupaiids (Mammalia, Scandentia) and its phylogenetic implications
  • E. Sargis
  • Biology
    Journal of morphology
  • 1 November 2002
TLDR
The hindlimb of Ptilocercus seems to be habitually flexed and has more joint mobility, a condition necessary for movement on uneven, discontinuous arboreal supports, and PtilOCercus should be considered in any phylogenetic analysis that includes Scandentia.
Terrestrial adaptations in the postcranial skeletons of guenons.
  • D. Gebo, E. Sargis
  • Geography
    American journal of physical anthropology
  • 1 March 1994
TLDR
It appears that significant morphological modification for terrestriality has occurred twice within the diverse radiation of living guenons with C. aethiops perhaps representing a third group in the making.
The grasping behaviour, locomotion and substrate use of the tree shrews Tupaia minor and T. tana (Mammalia, Scandentia)
TLDR
It is proposed that arboreal tupaiids, such as Ptilocercus lowii and T. minor, may represent better models for early primates than didelphid marsupials because they are capable of grasping and are more closely related to primates.
