Platysolenites antiquissimus

Platysolenites antiquissimus est species fossilis foraminiferorum, in stratis Cambrii inferioris inventa, ergo veterrima omnium foraminiferorum species nota.McIlroy, D., Green, O. R. & Brasier, M. D. (2001) Palaeobiology and evolution of the earliest agglutinated Foraminifera: Platysolenites, Spirosolenites and related forms. Lethaia, 34 (1): 13–29.

Testa Platysolenitis est tubiformis, cylindrica, agglutinata, scilicet e granis praesertim silicae confecta, 0.01–3 mm diametro, longitudine maximi inventi fragmenti ca. 5 cm. Ad initium cylindri invenitur proloculus sphaericus.
