“…In contrast to these two specimens, the Kuruksay specimens of Para. sushkini possess a maxillary sinus, which might indicate that they are closer to the crown line-age of Macacina (Nishimura et al, 2007). However, the present findings do not strongly support such a phyletic view.…”

“…Unfortunately, knowledge is limited about any morphological variation in the nasal region of Papionina (Koppe and Ohkawa, 1999). The maxillary sinus seems to form partially in the genus Papio (Nishimura et al, 2007). Thus, surveys of the morphological variation in papionins, especially Papionina, are needed to understand the phyletic position of the fossil papionins better.…”

“…Both species, in adults, had a nasal cavity expanding laterally to make a thin maxillary body at the anterior level of the cheek teeth. Nevertheless, at the posterior level, the Senèze cranium, FSL41336 (Collections de Géologie, Université Claude-Bernard Lyon-1, Lyon, France), has no maxillary sinus and a thick maxillary body filled with cancellous bone , whereas the Kuruksay adult cranium, PIN3120-523 (Paleontological Institute, Russian Academy of Sciences, Moscow, Russia), has a maxillary sinus pneumatizing the thick maxillary body and extending into the alveolar process [Nishimura et al, 2007]. The findings would demonstrate intrageneric variation in the presence or absence of a maxillary sinus in the extinct genus .…”

Paradolichopithecus was a large cercopithecine primate that existed in Eurasia from the middle Pliocene to the early Pleistocene. Para. arvernensis from the late Pliocene of Senèze, France, shows no maxillary sinus, whereas Para.sushkini from the late Pliocene of Kuruksay, Tajikistan, has this feature. In this study, we examined a new maxillary specimen of Para. gansuensis from the early Pleistocene of Longdan, China. The Longdan maxilla had lost its facial part, which exposed the internal floor of the nasal region. The nasal floor expands laterally, making the maxillary body thin at the P³–M² level and thick at the M³ level and extending to the maxillary tubercle. Such a topography is seen in the Senèze and Kuruksay crania. The Longdan maxilla shows no evidence of the formation of a maxillary sinus within the inferior portion of the thick maxillary body, as is seen in the Senèze cranium. Such a configuration could reflect the absence of a maxillary sinus in the Longdan specimen. Eastern Para. gansuensis might have dispersed eastward retaining a primitive condition, while central Para. sushkini would have acquired this feature independently in central Eurasia.

Extant cercopithecoid monkeys, except macaques, are distinguished among primates by their lack of paranasal pneumatization, including the maxillary sinus (MS). Analysis of this structure, widespread among Eutheria, suggests that its loss occurred in the cercopithecoid common ancestor; thus, the presence of the MS in macaques is not strictly homologous to that in other primates. CT analysis of the fossil species Victoriapithecus macinnesi supports this view, demonstrating the lack of the MS in this stem cercopithecoid. Recent evidence, however, has documented the presence of the MS in extinct cercopithecoids from the late Miocene and Pliocene. This study reports on CT examination of two fossil crania attributed to Cercopithecoides williamsi from South Africa, dated in the range, 3.0-1.5 Ma. BF 42a is a complete cranium from Bolts Farm; MP113 is an intact facial skeleton, including the anterior cranial vault, from the Makapansgat Limeworks. Both demonstrate MS presence, unknown in extant colobines and unexpected in most cercopithecoid monkeys. The relative size of the MS of BF 42a is similar to that of extant tropical and subtropical macaques. The presence of sinuses in several extinct colobines suggests that our understanding of the evolutionary history of these primates, and of the MS, is incomplete, and that other fossil cercopithecoids should be examined for this feature. The developmental plasticity exhibited in this feature, indicated by multiple loss and reemergence, provides further evidence that paranasal pneumatization has undergone a complex history of suppression and expression.
