Evidence of binary division in mature central capsules of a collosphaerid colonial radiolarian: Implications for shell ontogenetic patterns in modern and fossil species
(Coquina Press, 1998)Evidence is presented from fossil shells and living species of the colonial radiolarian Acrosphaera that maturer central capsules with shells can produce daughter central capsules and shells by binary fission. These data ... -
Shell ontogeny in radiolarians
(International Association of Radiolarian Paleontologists, 1998)The ontogeny of the shells in modern and ancient radiolarian species, Acrosphaera cyrtodon were observed by scanning and transmission electron microscopy. The shells of A. cyrtodon were obtained from core samples collected ...
