Platysolenites antiquissimus
Eichwald, 1860

Platysolenites antiquissimus est species fossilis foraminiferorum, in stratis Cambrii inferioris inventa, ergo veterrima omnium foraminiferorum species nota.^[1]

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.^[1]

Platysolenites ad familiam Hyperamminidarum ordinis Astrorhizidorum pertinet,^[2] aut, iuxta aliam propositionem, ad familiam Bathysiphonidarum eiusdem ordinis.^[3] Olim ad Annelida pertinere censebatur.^[1]

Fossilia Platysolenitum in Anglia, Cambria,^[1] Norvegia,^[4]^[5] Estonia, Rossia, et Terra Nova inventa sunt.^[1]
