The Neonatal Line (NNL) of the tooth serves as a unique identifier, allowing us to distinguish whether a child survived birth. This line is essential for assessing the age at death of infants from skeletal remains found in archaeological contexts. Our primary objective is to accurately determine the age of infant intramural inhumations from the Iberian Iron Age (8th-1st centuries BC) by analyzing histological sections of tooth germs. Due to their fragility and high susceptibility to taphonomic factors, these samples are challenging to handle. By accurately assessing their age, we aim to classify individuals into various stages of infant mortality, which will help reconstruct infant mortality patterns in these populations.

从牙齿组织学重建伊比利亚铁器时代人群的婴儿死亡率


牙齿的新生儿线 （NNL） 作为唯一标识符，使我们能够区分孩子是否在出生后存活下来。这条线对于评估考古环境中发现的骨骼遗骸中婴儿的死亡年龄至关重要。我们的主要目标是通过分析牙胚的组织学切片，准确确定伊比利亚铁器时代（公元前 8-1 世纪）婴儿壁内埋葬的年龄。由于它们的脆弱性和对 taphonomic 因子的高度敏感性，这些样品难以处理。通过准确评估他们的年龄，我们的目标是将个体分为婴儿死亡率的不同阶段，这将有助于重建这些人群的婴儿死亡率模式。
