摘要作为大陆架和斜坡实验埋藏学倡议项目的一部分，在巴哈马和墨西哥湾的几个深度和环境设置中部署的Callinectes sapidus的遗骸的检查显示，所有标本均匀，强烈退化，除了盐水渗漏设置。所有部位的表皮材料破碎和丢失与未展开样本中观察到的不同骨骼元素的表皮内钙化程度相关。爪、最后一个前外侧棘的尖端和下颌骨是最持久的遗骸。在盐水渗漏区，保存得非常好，产生了关节骨骼元素和一些软组织。用交叉偏振光和计算机断层扫描检查对照标本中的角质层，记录了高度钙化与部署后剩余的外骨骼部分的对应关系。
Abstract Examination of remains of Callinectes sapidus deployed in several depth and environmental settings in the Bahamas and Gulf of Mexico as part of the Shelf and Slope Experimental Taphonomy Initiative project revealed that all specimens were uniformly and strongly degraded except those in brine-seep settings. Fragmentation and loss of cuticular material at all sites was correlated to the degree of calcification within the cuticle of different skeletal elements as observed in the undeployed specimens. Claws, tips of the last anterolateral spine, and mandibles were the most durable remains. In brine-seep areas, extraordinary preservation yielded articulated skeletal elements and some soft tissue. Examination of the cuticle in control specimens with cross-polarized light and computed tomographic scanning documents the correspondence of high degrees of calcification with portions of the exoskeleton remaining after deployment.
