Fine structure of silicoflagellate double skeletons

“…39 Distephanus LMs Takahashi and Blackwelder (1992) figs. 3-2, 3-3, 3-5 Distephanus, Octactis LMs Hallegraeff (2005) fig Bukry (1976) and McCartney and Loper (1989). The skeleton is made of rod-shaped "elements" which make up the basal ring and apical structure.…”

Extant silicoflagellates from the Northeast Aegean (eastern Mediterranean Sea): Morphologies and double skeletons

“…Looking at the species' descriptions and illustrations, these two species can be, in most cases, considered as synonyms, although attempts have been made to further separate varieties and types based on some morphological features (e.g. Bukry, 1976bBukry, , 1980Locker and Martini, 1986). We follow here Bukry (1976a) and Abe et al (2015) (1) 6-sided, elongated apical ring, apical view (2AMT-3, 10 m); (2) 7-sided, apical view (2AMT-6, 10 m); (3) 7-sided, lateral view (2AMT-3, 10 m); (4) 7-sided, open basal ring, apical view (2AMT-6, 10 m); (5) 6-sided with an additional vestigial basal ring spine, apical view (2AMT-2, 20 m); (6) 7-sided, large, with twisted struts, apical view (2AMT-2, 20 m); (7) 6-sided with one additional strut, abapical view (2AMT-2, 20 m); (8) 7-sided with tripartite apical ring, apical view (2AMT-3, 20 m); (9) 6-sided, with very small apical ring and spines on the struts, apical view (2AMT3-10); (10) 6-sided with aberrant apical ring transformed in a plate (2AMT-3, 2 m); (11) 6-sided with an additional basal ring spine and deformed apical ring (LM, 2AMT-2, 2 m); (12) 7-sided, with rotated struts, Black Sea specimen (BS3-22).…”

Silicoflagellates and Actiniscus : vertical fluxes at Pacific and Atlantic sediment trap stations

“…Apical bar aligned in longitudinal position, about Ij3 of major basal ring diameter, and convex with an apical spine. REMARKS: The specimens studied here are conformable with D. stapedia stapedia ilustrated by Bukry (1976Bukry ( , 1980 Haeckel's (1887) original ilustrations (31 ¡.m in major basal ring diameter). A gradual reduction in size of this species has been observed in the geologic record (Bukry, pers.…”
