“…Radiolaria are divided into Polycystina and Spasmaria based on molecular phylogenetic studies (Sierra et al 2013 ). Polycystina are a radiolarian group with an opal skeleton, and their extant groups are classifi ed into Orders Collodaria, Nassellaria and Spumellaria (Suzuki and Aita 2011 ).…”

“…Nikolaev et al ( 2004 ) illustrated a sister group of Foraminifera and Radiolaria in Rhizaria, and Pawlowski and Burki ( 2009 ) separated Foraminifera from a sister group of Radiolaria. The sister relationships between Foraminifera and Radiolaria are now widely accepted by studies with cDNA libraries (Sierra et al 2013 ) and polyubiquitin insertion (Ishitani et al 2011 ), but the position of Foraminifera has been unstable. For instance, the Foraminifera clade comprises a sister group with Polycystina and Spasmaria (a group of Acantharia and Taxopodia) in a combined 18S and 28S rDNA alignment (Krabberød et al 2011 ).…”

The oldest marine protist fossil goes back 1.8 Ga (Statherian, Paleoproterozoic), and the oldest dinosterane biomarkers 1.6 Ga (Calymmian, Mesoproterozoic). The probable heterotrophic agglutinated microfossil appeared when marine metazoans appeared in the Ediacaran. Multichambered foraminifers appeared around the start of biomineralization in Small Shelly Fossils in the early Cambrian. The fi rst fossilizable radiolarian polycystine is likely to have appeared in the period of the Cambrian Explosion. After the initial appearance period, the emergence of fossilizable skeleton formative ability was concentrated in fi ve short geological time intervals: (1) the Middle to Late Devonian for calcareous benthic foraminifers; (2) the Carnian to the Rhaetian (Triassic) for the "switching on" of fossilizable dinofl agellate cysts, nannoliths, coccoliths and calcareous cysts, and probably the molecular appearance of diatoms; (3) the Toarcian-Aalenian Ages for diversifi ed dinofl agellates and coccolithophores, the establishment of symbiosis in radiolarian Acantharia and the appearance of planktic lifestyle in foraminifers; (4) the Albian-Maastrichtian Ages for the rapid accumulation of coccolithophores, the start of skeletogenesis both in silicofl agellates and marine centric diatoms, molecular appearance of both araphid and raphid diatoms, and the appearance of fossilizable araphid diatoms; and (5) the middle to late Eocene for the appearance of fossilizable raphid diatoms and radiolarian colonial collodarians and the continuous occurrences of ebridians. The establishment of the modern-type marine protist world was concluded in the late Eocene by the appearance of collodarians, the continuous occurrences of ebridians, and the substituted silicon precipitation marine protists as diatoms.

“…Since the site is situated close to the Carbonate Compensation Depth (CCD), the planktonic foraminiferal tests that are common at similar depths in the North Atlantic are largely absent. Instead, the coarser fractions of the sediment contain numerous tests of 'radiolarians', a polyphyletic grouping that is no longer recognised as a distinct taxonomic unit (Sierra et al, 2013). The majority of these tests appear to be those of polycystines rather than the more dissolutionprone phaeodarians (Takahashi et al, 1983), although we have not attempted to differentiate these two groups rigorously.…”

“…Phaeodaria have siliceous skeletons, and their overall appearance is similar to that of radiolarians. Yet, molecular studies have revealed that this group is phylogenetically different from Radiolaria (Nikolaev et al 2004, Sierra et al 2013, Nakamura et al 2015. Phaeodarians now belong to the phylum Cercozoa, included in Rhizaria (SAR), together with Radiolaria and Foraminifera (Howe et al 2011, Adl et al 2012.…”

Optics-based surveys of large unicellular zooplankton: a case study on radiolarians and phaeodarians

Optics-based surveys for large unicellular zooplankton were carried out in five different oceanic areas. New identification criteria, in which radiolarian-like plankton are categorized into nine different groups, are proposed for future optics-based surveys. The autonomous visual plankton recorder (A-VPR) captured 65 images of radiolarians (three orders: Acantharia, Spumellaria and Collodaria) and 117 phaeodarians (four taxa: Aulacanthidae, Phaeosphaerida, Tuscaroridae and Coelodendridae). Colonies were observed for one radiolarian order (Collodaria) and three phaeodarian taxa (Phaeosphaerida, Tuscaroridae and Coelodendridae). The rest of the radiolarian orders (Taxopodia and Nassellaria) and the other phaeodarian taxa were not detected because of their small cell size (< ca. 400 µm).
