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.
Résumé
Les spermatozoïdes fossiles sont très rares. Parmi les huit cas que nous rapportons ici, dont deux cas de spermatophores sans spermatozoïdes visibles, six sont des fossiles conservés dans l’ambre. Les six concernent des animaux pratiquant un transfert indirect des spermatozoïdes par l’intermédiaire de spermatophores ou de spermatodesmes. La préservation d’organites subcellulaires montre une fois de plus que l’ambre est un milieu de conservation exceptionnel.
