We investigated the mineralogical and chemical signatures of enigmatic microspherules commonly recovered in conodont residues and referred to in literature as ‘conodont pearls.’ Comparison between these ‘pearls,’ associated conodonts and other phosphatic skeletal elements present in the same stratigraphical level was run in an effort to reveal any possible relation between ‘conodont pearls’ and the joined groups so to finally provide a response on the affinity of these spherules.

“牙形石珍珠”不属于牙形石

我们研究了通常在牙形石残留物中回收并在文献中称为“牙形石珍珠”的神秘微球的矿物学和化学特征。对这些“珍珠”、相关牙形石和同一地层中存在的其他磷酸盐骨架元素进行了比较，以揭示“牙形石珍珠”与连接组之间的任何可能关系，从而最终提供对这些亲和性的反应小球。
