If the fetal remains are found in a fetal position and are wholly within the pelvic cavity of the adult, the fetus died and was interred before delivery. The pregnant woman may therefore have died due to labor complications. If the infant is found alongside the adult, with the head oriented in the same direction as the adult, then the infant was delivered, whether naturally or by caesarian incision, around the time of death, and thereafter interred. Delivered infants have also been interred between or alongside the tibiae (shins), but the infant is still oriented in the same direction as the adult. If the majority of the fetal remains are in the pelvic cavity of the adult, yet the legs are extended and/or the cranium lies among the ribs, then the infant may have been delivered and then placed on top of the mother's torso before burial. As both bodies skeletonized, the infant's bones would have settled among the mother's ribs and vertebrae. If the fetal remains are complete and in a position inferior to and in-line with the pelvic outlet, with the head oriented opposite to that of the mother (toward the foot of the coffin or grave), then there is the possibility of coffin birth. Evidence for postmortem fetal extrusion may be less ambiguous when the fetal remains are found to lie within the pelvic outlet of the adult, thus indicating that partial extrusion had occurred during decomposition. In 1975, it was reported that during the excavation of a medieval cemetery in Kings Worthy, England, fetal remains appeared to lie within the birth canal of the skeleton of a young woman, with the fetal cranium external to the pelvic outlet and between the two femora (thigh bones) and the fetal leg bones clearly within the pelvic cavity. Other cases of coffin birth at archaeological sites have been described, such as in 1978 at a Neolithic site in Germany, at a medieval site in Denmark in 1982, and in 2009 at an Early Christian period site at Fingal, Ireland. A coffin birth was also described in a 2011 episode of the BBC show History Cold Case, featuring the Roman era remains of a woman and three neonates discovered near Baldock, Hertfordshire. Another was identified in 2006 in a 14th-century Black Death cemetery in Genoa, Italy.
== Applicability of diagnosis == Because postmortem fetal extrusion is so rare, and occurs under highly idiosyncratic conditions regarding the individual and the ambient environment, this phenomenon has not been studied for possible applications to forensic investigation. Even if the study of postmortem fetal extrusion could lead to improved investigative methods, experimental research would be highly problematic. At present, forensic scientists have at their disposal an array of established techniques and procedures for a death investigation at the stages of decomposition when postmortem fetal extrusion typically occurs. In archaeology, the study of mortuary context, that is, the interpretation of the postmortem treatment of the dead, whether an individual or as pertains to patterns within a group, has led to the development of hypotheses on social status and/or hierarchy regarding many cultures, ancient and extant. In addition, the determination of whether or not delivery actually occurred before death has a bearing on analyses of the mother's population, as the concentration of trace elements differ markedly between the skeletons of prepartum adult women (before giving birth) and women who are lactating; the identification of coffin birth would lead to more accurate analyses of the number of lactating women in a population or the rate of maternal mortality. It is therefore necessary for investigators to be able to recognize postmortem fetal extrusion when encountered in an excavated burial.
