Braarudosphaera bigelowii qirg'oqdir koksolitofora 100 million yillik tarixga oid fotoalbomlarda. Oila Braarudosphaeraceae bilan bir hujayrali qirg'oq fitoplanktonik suv o'tlari ohakli chaqirilgan besh karra simmetriya bilan tarozilar pentalitlar. 12 tomoni bilan u a dodekahedral bo'ylab, taxminan 10 mikrometr.[1]

(A) ning hujayrasining SEM tasviri B. bigelowii 12 ta pentitalit bilan o'ralgan. Pentalit (ning ohakli shkalasi Braarudosphaeraceae) ko'k ochiq beshburchak bilan ko'rsatilgan beshta trapezoidal segmentdan iborat. Qora o'q o'lchovlar o'tkazilgan joyda "pentalitning yon uzunligini" bildiradi. (B) pentalitning SEM tasviri B. bigelowii (proksimal tomon). (C) Laminar tuzilishni ko'rsatadigan oldingi rasmda proksimal tomonni yoping. (D) - (F) uch xil namunadagi nurli mikroskop tasvirlari.[1]
