BACKGROUND
Six early juveniles were recovered from U.W. 101 (Dinaledi Chamber), U.W. 102 (Lesedi Chamber), and U.W. 110 in the Rising Star cave system.
AIM
This paper develops the information for the early juvenile life stage, as defined by a combination of deciduous and permanent dentition, and the eruption of the first permanent molar.
SUBJECTS AND METHODS
The growing number of young individuals recovered from the Rising Star cave system allows us to gain a better understanding of their variation, or lack thereof, and provides a basis to estimate broad ranges for age at death of the individuals. The individuals are identified and described through craniodental remains and spatial associations.
RESULTS AND CONCLUSION
Our results show that the teeth are remarkably consistent across the localities in their metric and non-metric traits, and our analyses refine previous estimations on dental eruptions with the first permanent molar erupting first in the sequence among permanent teeth.
背景
在 Rising Star 洞穴系统的 U.W. 101（Dinaledi 厅）、U.W. 102（Lesedi 厅）和 U.W. 110 中发现了六具幼年个体。
目的
本文旨在描述幼年个体的生活阶段，其定义为乳牙和恒牙的混合以及第一恒磨牙的萌出。
受试者和方法
从 Rising Star 洞穴系统中发现的越来越多的年轻个体使我们能够更好地了解他们的变异情况，或缺乏变异情况，并为估计个体的死亡年龄提供了基础。这些个体通过颅面骨骼和空间关联来识别和描述。
结果和结论
我们的结果表明，这些牙齿在度量和非度量特征上在不同地点之间非常一致，并且我们的分析进一步细化了之前关于牙齿萌出的估计，即第一恒磨牙在恒牙序列中首先萌出。
