Evolution of postural diversity in primates as reflected by the size and shape of the medial tibial facet of the talus.
Boyer, Doug M; Yapuncich, Gabriel S; Butler, Jared E; Dunn, Rachel H; Seiffert, Erik R (American journal of physical anthropology, 2015-05)Comprehensive quantification of the shape and proportions of the medial tibial facet (MTF) of the talus (=astragalus) has been lacking for Primates and their closest relatives. In this study, aspects of MTF form were quantified ... -
Internal carotid arterial canal size and scaling in Euarchonta: Re-assessing implications for arterial patency and phylogenetic relationships in early fossil primates.
Boyer, Doug M; Kirk, E Christopher; Silcox, Mary T; Gunnell, Gregg F; Gilbert, Christopher C; Yapuncich, Gabriel S; Allen, Kari L; ... (12 authors) (J Hum Evol, 2016-08)Primate species typically differ from other mammals in having bony canals that enclose the branches of the internal carotid artery (ICA) as they pass through the middle ear. The presence and relative size of these canals ... -
New Myzopodidae (Chiroptera) from the Late Paleogene of Egypt: Emended Family Diagnosis and Biogeographic Origins of Noctilionoidea
Gunnell, Gregg F; Simmons, Nancy B; Seiffert, Erik R (PLoS One, 2014-02-04)Myzopodidae is a family of bats today represented by two extant species of the genus Myzopoda that are restricted to the island of Madagascar. These bats possess uniquely derived adhesive pads on their thumbs and ankles ... -
Quantification of the position and depth of the flexor hallucis longus groove in euarchontans, with implications for the evolution of primate positional behavior.
Yapuncich, Gabriel S; Seiffert, Erik R; Boyer, Doug M (American journal of physical anthropology, 2017-06)On the talus, the position and depth of the groove for the flexor hallucis longus tendon have been used to infer phylogenetic affinities and positional behaviors of fossil primates. This study quantifies aspects of the flexor ...
