SPECIES, AUTHORITY A. dongyingensis (Ke & Shi) Elsik, Ediger & Bati 1990, p. 96.
LOCATION Panshan, Liaoning Province, Coastal region of Bohai, China.
ORIG DESCRIPTION* Spores 90-99 x 37-48 µm. Outline ovate. Three-celled, cells gradually diminishing in size from one end to the other, becoming very small, but both ends rounded. Septa hyaline, with a ruptured tear in the middle, but tears non-poroid. Spore wall of medium thickness, surface psilate or scabrate. Outer contour line smooth.

EMENDED DESCRIPTION (Elsik, Ediger & Bati): Diporate, tricellate (rarely tetracellate) fungal spores with two (rarely three) transverse septa. The spore outline is obovate, symmetrical along a straight axis. The outline can be indented slightly over the septa. The cells are arranged in a graded series of diminishing size. The pores are simple, at the ends of the spore, 1-3 µm in diameter. The spore wall can be slightly thickened around the distal pore. The spore wall is 1.5-2 µm thick, thickest over the largest, distal, cell. The septal pore is obvious. The septa are sometimes broken through the septal pore, forming septal flaps. The thickness of the septa is variable, between 3-5 µm.
COMMENTS* (Elsik, Ediger & Bati): Anatolinites dongyingensis appears to be endemic to some Turkish Tertiary basins, such as the Thrace Basin in northwestern Turkey and the Tekman Basin in eastern Turkey. The species occurs from the Upper Eocene to the Lower? Miocene in the northern Thrace Basin, where it can be considered as an index fossil for the Upper Oligocene, based on its abundance in those strata (Ediger, 1981; Ediger and Alisan, 1989). The overall range of Anatolinites dongyingensis apparently is Late Paleocene to Early? Miocene. The spores illustrated by Ke & Shi (1978) are from the Oligocene of the Bohai region of China. The material illustrated by Sepúlveda(1980) is apparently from Upper Paleocene strata. Norris (1986) did not illustrate an equivalent specimen, but he did include a specimen from the lower part of the Richards Formation, Middle and Upper Eocene (undifferentiated), of the Nuktak C-22 well of the Mackenzie Delta area, Nortwest Territories, Canada, in Sepúlveda and Norris (1982). Poorly preserved specimens also occur in the Middle and Upper? Eocene of the Green River area, Washington.

The length:width ratio of Anatolinites dongyingensis is about 2:1. Spores with a length:width ratio less than 15:1 and subdivided by two transverse septa are included in Kendrick & Nag Raj's (1979) revised definition of phragmospores. Dicellaesporites mollis Ke & Shi 1978 and Multicellaesporites tricyclosus Ke & Shi 1978 possibly are aberrant forms of Anatolinites dongyingensis.

K&J REMARKS Elsik et. al. (l.c.) stated that they designated the holotype cited above; however, Ke & Shi already had designated the same specimen as type. Plate 9, fig. 32, Kalgutkar and Jansonius’s illustration of the type of this species (and of the genus), does not show a pore, because Kalgutkar and Jansonius (2000) could not make out a pore in the original illustration. Other specimens with the same overall morphology may show pores.
