Primate Communication: A Multimodal Approach
Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions toExpand
EquiFACS: The Equine Facial Action Coding System
EquiFACS provides a method that can now be used to document the facial movements associated with different social contexts and thus to address questions relevant to understanding social cognition and comparative psychology, as well as informing current veterinary and animal welfare practices.

Finite element analysis of performance in the skulls of marmosets and tamarins
3D finite element models of the marmoset Callithrix jacchus and the tamarin Saguinus fuscicollis are used to investigate the performance of the cranium under loading regimes that mimicked unilateral molar biting and bark‐gouging. Expand
Brief communication: MaqFACS: A muscle-based facial movement coding system for the rhesus macaque.
Here, the development of a muscular-based system for measuring facial movement in rhesus macaques is described based on the well-known FACS and ChimpFACS, which describe facial movement according to the action of the underlying facial musculature, which is highly conserved across primates. Expand

The present review synthesizes the evidence from gross muscular, microanatomical, behavioral and neurobiological studies in order to provide a preliminary analysis of the factors responsible for the evolution of primate facial musculature with comparisons to general mammals. Expand
Development of a strain of rabbits with congenital simple nonsyndromic coronal suture synostosis. Part II: Somatic and craniofacial growth patterns.
Results revealed that by 1.5 weeks of age the completely synostosed animals already exhibited brachycephalic cranial vaults, midfacial hypoplasia, and increased flattening of the cranial base compared to unaffected siblings. Expand
Paedomorphic Facial Expressions Give Dogs a Selective Advantage
It is found that dogs who exhibited facial expressions that enhance their neonatal appearance were preferentially selected by humans, adding to the understanding of early dog domestication as a complex co-evolutionary process. Expand
Selection for universal facial emotion.
The authors show that although some facial muscles are not present in all individuals, and often exhibit great asymmetry (larger or absent on one side), the facial muscles that are essential in order to produce the universal facial expressions exhibited 100% occurrence and showed minimal gross asymmetry in 18 cadavers.

Muscles of facial expression in the chimpanzee (Pan troglodytes): descriptive, comparative and phylogenetic contexts
A detailed description of the facial muscles of the chimpanzee is presented, framed in comparative and phylogenetic contexts, through the dissection of preserved faces using a novel approach, to support previous studies that describe an elaborate and highly graded facial communication system in this species.
