摘要

精子化石极为罕见。在这里报告的8例病例中，包括2例看不到精子细胞的精囊，有6例是保存在琥珀中的化石。所有六项研究都涉及通过精子囊或精子原粒间接精子转移的动物。亚细胞细胞器的保存再次表明琥珀是一种非凡的保存介质。

Synopsis of rare fossil animal spermatozoa in amber and sedimentary deposits

Fossil spermatozoa are extremely rare. Among the eight cases reported here, including two cases of spermatophores without visible sperm cells, six are fossils preserved in amber. All six concern animals with indirect sperm transfer by means of spermatophores or spermatodesmids. Preservation of subcellular organelles shows once again that amber is an extraordinary preservation medium.
