SPECIES, AUTHORITY D. oblongatus (Ke & Shi) Norris 1986, p. 22.
LOCATION Panshan, Liaoning Province, Coastal region of Bohai, China; (Norris): Imperial Nuktak C-22 Well, Mackenzie Delta Region, District of Mackenzie, N.W.T., Canada.
ORIG DESCRIPTION* Spores 30 x 21 µm. Outline elliptical, ends rounded-acute. Two-celled, septum hyaline, 1 µm in width, ring-shaped. Diporate, pores fairly small, simple, about 1.5 µm in diameter. Spore wall 1 µm thick, two-layered, outer and inner layers are of about equal thickness, surface psilate.
COMMENTS* Spores in this species are distinguished from those in Dyadosporonites schwabii Elsik 1968 by their slightly larger body size and their elliptical outline. They differ from members of Dyadosporonites subovalis Sheffy & Dilcher 1971 on account of their larger size and the fact that neither of their ends is truncated.
