Strepsirrhini - Wikipedia
Strepsirrhini or Strepsirhini (/ ˌ s t r ɛ p s ə ˈ r aɪ n i / ⓘ; STREP-sə-RY-nee) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia.

SKULLS AND DENTITION. Strepsirhine skulls have: A medium-sized, rounded brain case; Relatively large eye sockets; A forwardly directed orbit for binocular vision - the orbit is relatively larger in nocturnal species than diurnal species; A complete bony bar on the outer margin of the orbit to support the outer edge of the eye.
Deep evolutionary roots of strepsirrhine primate labyrinthine ...
2009年12月21日 · We studied this question in strepsirrhine primates with the aim to assess the potential and limitations of using the inner ear as a phylogenetic marker. Geometric morphometric analysis showed that the labyrinthine morphology of extant strepsirrhines contains a mixed locomotor, allometric and phylogenetic signal.
Primate Cranial Diversity | Learn Science at Scitable - Nature
Major axes of primate cranial variation often reflect reorganizations of cranial structure that define important evolutionary events such as the strepsirrhine-haplorhine divergence or the origin of...
Also, the skull morphology in strepsirrhines and haplorrhines is clearly distinct, and it is shown here that differences between and within infraorders can be traced back to differences in developmental modes. According to a hypothesis proposed by Beard (1988), “strepsirrhinism” represents the prim-itive condition of the primate skull.
Evolution and development of the strepsirrhine primate skull
2008年1月1日 · Also, the skull morphology in strepsirrhines and haplorrhines is clearly distinct, and it is shown here that differences between and within infraorders can be traced back to differences in...
Evolution and development of the strepsirrhine primate skull
This first descriptive comparison of the whole skull morphology within the two extant sloth genera is presented, combining geometric morphometric approaches with comparative anatomy to explore the patterns of the intra‐ and interspecific morphological variation of the skull with regard to several factors such as phylogeny, geography ...
The evolution of palate shape in the Lepilemur‐Cheirogaleidae …
2020年7月14日 · We investigated potential influences on palate shape in these taxa and several outgroups using geometric morphometrics. Our sample included representatives of four extant strepsirrhine families, Cheirogaleidae (including Lepilemurinae), Lemuridae, Indriidae, and Galagidae, and one subfossil Megaladapis.
Do Muscles Constrain Skull Shape Evolution in Strepsirrhines?
Here, we aim to study the impacts of the masticatory muscles on the shape of the cranium and the mandible as well as their co-variation in strepsirrhine primates. To do so, we use 3D geometric morphometric approaches to assess the shape of each bone of the skull of 20 species for which muscle data are available in the literature.
