Previous attempts to use the development of the tympanic plate as an aging standard for fetal and infant cranial remains have either produced only a developmental sequence (Anderson, 1960), or a sequence for which age has been estimated using another independent aging standard (Weaver, 1979). Following an evaluation of the first three stages of development of the tympanic plate using a known‐age sample of fetal and infant skeletal remains, a simple test of inter‐observer agreement, Cohen's coefficient of agreement (Cohen, 1960), is demonstrated using the developmental stages.
