In a recent Louisiana forensic anthropology case, it was necessary to attempt species identification of six small bone fragments. The primary concern was whether or not they matched the fractured humerus of a woman killed by two shotgun blasts and then disposed of in the Mississippi River. These tiny fragments were recovered by law enforcement officers inside a jeep pickup and at the gas station where the vehicle had been cleaned. The police suspect claimed that these fragments were from a deer that he had recently killed. The small size of the pieces precluded positive recognition of human versus nonhuman origin based upon gross morphology and cortical thickness. Microscopic examination was possible. This analysis involved comparison of the unknown specimens to reference deer and human thin sections including bone recovered from the woman during autopsy. Examination of the jeep and gas station fragments revealed no plexiform bone, secondary (not primary) osteons, and variability in size and shape of the osteons and Haversian canals. These and other variables identified the bone fragments as human.
在路易斯安那州最近的一起法医人类学案件中，有必要对六块小骨碎片进行物种鉴定。主要关注点在于这些碎片是否与一名被两枪霰弹击中后抛尸于密西西比河的女性的肱骨骨折处相匹配。这些微小碎片是执法人员在一辆吉普皮卡内以及车辆被清洗的加油站找到的。警方嫌疑人声称这些碎片来自他最近猎杀的一头鹿。由于碎片尺寸过小，无法基于大体形态和皮质厚度来明确判断是人类还是非人类的骨头。进行显微镜检查是可行的。该分析包括将未知标本与鹿和人类的参考薄片进行比较，其中包括在尸检时从该女性身上获取的骨头。对吉普车内和加油站找到的碎片进行检查后发现，没有板层骨、次级（而非初级）骨单位，且骨单位和哈弗斯管的大小和形状存在差异。这些以及其他变量表明这些骨碎片属于人类。
