   * The nature of the **material** has significant impact on the reliability of the radiocarbon date. **Short-lived** plants and textiles (twigs, textiles etc.) and bones are more likely to produce precise and accurate absolute dates than long-lived materials (e.g. shells, wood) or charcoal.   * The nature of the **material** has significant impact on the reliability of the radiocarbon date. **Short-lived** plants and textiles (twigs, textiles etc.) and bones are more likely to produce precise and accurate absolute dates than long-lived materials (e.g. shells, wood) or charcoal.
   * **Plateaus in the calibration curve**, i.e. periods of increased production of <sup>14</sup>C in the Earth’s atmosphere, can cause the errors of the radiocarbon dates to increase drastically, obscuring the absolute chronology. One such period occurred during the Early Dynastic era, between ca. 2820-2580 BC (Reimer et al. 2012). This problem can only be alleviated with the production of new radiocarbon dates.   * **Plateaus in the calibration curve**, i.e. periods of increased production of <sup>14</sup>C in the Earth’s atmosphere, can cause the errors of the radiocarbon dates to increase drastically, obscuring the absolute chronology.
