A cross-sectional sample of 121 colony-born saddle-back tamarins, Saguinus fuscicollis, was examined to identify the sequence and timing of dental eruption and epiphyseal union. The state of dental development of the deciduous and permanent dentitions was recorded as erupted or non-erupted on the basis of gingival penetration. Eighteen areas of union of long bone epiphyseal and other secondary centers, the union of the primary elements of the innominate, and the spheno-occipital synchondrosis were examined. The state of union at the areas was recorded on a three-point scale of not united, uniting, and united. The data indicated that deciduous incisors and canines were present at birth and that all deciduous teeth were erupted by 12 weeks. The first permanent tooth, M(1), erupted between weeks 16 and 23; the permanent dentition was fully erupted by 45 weeks. Union of the long bone epiphyses began in the third month at the distal humerus and continued until the first quarter of the second year. The secondary centers at the ischial tuberosity and iliac crest were united slightly later than four and six years of age, respectively. Regression analysis of the data indicate their potential use as parameters for predicting age in feral specimens.
对 121 只圈养出生的鞍背猕猴（Saguinus fuscicollis）的横断面样本进行了检查，以确定牙齿萌出和骺骨融合的顺序和时间。根据牙龈穿透情况，将乳牙和恒牙的牙发育状态记录为萌出或未萌出。检查了长骨骺和其他次级中心、骨盆骨主要元素以及蝶枕联合的 18 个融合区域。将各区域的融合状态记录在未融合、正在融合和已融合的三分制上。数据表明，出生时就有乳切牙和乳犬牙，所有的乳齿在 12 周时萌出。第一颗恒牙（M1）在 16-23 周时萌出；恒牙在 45 周时完全萌出。长骨骺的融合始于第三个月的肱骨远端，并持续到第二年的第一季度。坐骨结节和髂嵴的次级中心的融合时间分别晚于 4 岁和 6 岁。对数据的回归分析表明，它们可能被用作预测野生标本年龄的参数。
