Two lines of evidence reviewed here argue against the recent proposal that strepsirhinism is an apomorphous feature in primates, shared only by adapiforms and lemuriforms. These are (1) the presence of strepsirhinism in several extant taxa of nonprimate mammals, including Tupaiidae, Tenrecidae, Erinaceus,and Didelphis,and (2) the inferred presence of strepsirhinism not only in adapiforms, but also in all plesiadapiforms and omomyids for which the relevant anatomical regions are known. Therefore… 
Amphipithecine primates are stem anthropoids: cranial and postcranial evidence
TLDR
Cranial remains associated with an ulna from a single individual pertaining to the amphipithecine Ganlea megacanina are reported, confirming that postorbital closure appeared later than many anthropoid dentognathic characters and evolved convergently in extant tarsiers and anthropoids.
Evolution and development of the strepsirrhine primate skull
TLDR
This thesis shows that the cranial morphology of the Omomyidae – a basal haplorrhine taxon comprising the genera Rooneyia, Necrolemur and Microchoerus – is closer to that of extant strepsirrhines than to thatof haplor rhines, while the cranio-mandibular morphology of Tarsius is closer than that of other extant haplor Rhines, i.e., the anthropoids.
Evidence for a Grooming Claw in a North American Adapiform Primate: Implications for Anthropoid Origins
Among fossil primates, the Eocene adapiforms have been suggested as the closest relatives of living anthropoids (monkeys, apes, and humans). Central to this argument is the form of the second pedal
The phylogenetic position ofMahgarita stevensi: protoanthropoid or lemuroid?
TLDR
The results suggest that, among known prosimians, Mahgarita is the one most closely related to the Anthropoidea.
Ontogeny of the nasolacrimal duct in primates: functional and phylogenetic implications
TLDR
Developmental series of serially sectioned fetal, perinatal and adult specimens, in combination with juvenile and adult skulls subjected to high‐resolution computed tomography, reveal that the vertical NLC and NLD of adult tarsiers and anthropoids are produced by the degeneration of a more horizontal anterior arm of the NLD.

Diagnosis and Differentiation of the Order Primates
TLDR
It is found that there exists no evidence for either an "archaic primate" or a prosimian or an anthropoid grade and the goals of which can be much better served by a phylogenetic (not cladistic) classification.
Interrelationships among primate higher taxa
TLDR
Features of the ankle and wrist joints of several adapiform taxa provide an independent test of the preceding hypotheses and suggest that lemuriforms are monophyletic with respect to knownAdapiforms, but that adAPiforms nevertheless are their stem lineage (sensu Ax26).
Anatomy of the oro-nasal region of some species of Tenrecidae and considerations of Tupaiids and Lemurids.
TLDR
There are essential differences within the oro-nasal region of the Tenrecoidea although the material available for anatomical studies was limited and it is demonstrated that Setifer and Echinops possess an unpaired ductus nasopalatinus communis, which originates from the fusion of the paired nasopalatine ducts.

On the Tarsiiform Origins of Anthropoidea
TLDR
Many systematic papers of the past decade have employed a cladistic approach, but the notion of ancestor-descendant relationships, or to put it differently, that phena transform from antecedent phena, has been simply set aside.
Cranial Anatomy and Evolution of Early Tertiary Plesiadapidae (Mammalia, Primates)
TLDR
The Bighorn Basin of Wyoming is important paleontologically for two reasons: it is the only place in the world where the early Cenozoic diversification of mammalian life is recorded through such a long sequence of continental sediments representing virtually continuous deposition, and many areas of the Bighorns are richly fossiliferous, making it possible to trace evolutionary changes through time in much more detail than is possible elsewhere.
Comparison of Eocene Nonadapids and Tarsius
TLDR
The creation of family concepts for the Omomyidae Trouessart, 1879 (including Anaptomorphidae Cope, 1883 and Microchoeridae Lydekker, 1887) signifies that these groups were previously recognized as distinct from the Adap family.
