On taxonomic position of the family Dusenburyinidae (Foraminifera)

摘要

Among muitichambered uniserial foraminifers with an agglutinated or microgranular wall and aperture and aperture and chambers of different type representatives with subsphaedcal chambers and the aperture having the inner tooth are distinguished ms the separate order Dusenburyinida. Specimens of this order differs from those of the order Hormonisida, Mikhaievich, 1980 (subclass Hormosinana Mikhalevich, 1980, class Nodosariata Mikhalevich, 1992) in the apertural structure never seen in Nodosariata. The order Dusendburyinida is placed into the superorder Ataxophragmioida Fursenko, 1958, subclass Textulariana Mikhalevich, 1980 (class Rotaliata Mikhalevich, 1980). This order differs from other orders of the superorder Ataxophragmioida in the absence of the initial trochospiral part.
