在两种南美洲猴Saimiri sciureus和Saguinus nigricollis中检查颅缝闭合。寻找闭合序列作为骨龄的指标。一些缝线似乎是更可靠的决定因素的骨骼年龄比其他人，这些缝线和他们的顺序是不同的两个物种的审查。蝶枕软骨结合和上颚间缝的腭部显示出与年龄相关的规则融合。Saimiri的上颌骨前上颌骨缝也是年龄的可靠指标，而Saguinus的上颌骨前上颌骨缝则不是;然而，Saguinus的前蝶骨-后蝶骨结合有规律地闭合，而Saimiri的上颌骨前上颌骨缝则不是。Saimiri的预测序列为（1）上颌骨-前颌骨，（2）上颌骨-前颌骨，（3）蝶枕，（4）间颌骨。在Saguinus中，它是（1）前蝶骨-后蝶骨，（2）蝶枕，（3）间颌。这是可能的，缝合闭合的序列和在这一过程中的变异性可能表明遗传和分类的关系。
Cranial suture closure is examined in two species of South American monkeys, Saimiri sciureus and Saguinus nigricollis. Sequences in closure were sought as indicators of skeletal age. Some sutures seem to be more reliable determinants of skeletal age than others, and these sutures and their sequence of closure are different in the two species examined. The sphenooccipital synchondrosis and the palatal portion of the Interpremaxillary suture show regular fusion associated with age in both species. In Saimiri the maxillopremaxillary sutures are also reliable indicators of age, whereas they are not in Saguinus; however, in the latter the presphenoid-postsphenoid synchondrosis closes regularly whereas it does not in Saimiri. In Saimiri the predictable sequence is (1) maxillo-premaxillary, (2) transverse maxillo-premaxillary, (3) spheno-occipital, (4) interpremaxillary. In Saguinus it is (1) presphenoid-postsphenoid, (2) spheno-occipital, (3) interpremaxillary. It is possible that the sequences of suture closure and the variability in this process may indicate genetic and taxonomic relationships.
