Annotation: Abstract--The lingulid brachiopod species Bicarinatina kongakutensis n. sp. is recorded here from the Middle Devonian (Eifelian) Ulangarat unit in Arctic Alaska. A restudy of the type species, Bicarinatina bicarinata (Kutorga) from the Middle Devonian (Eifelian) of Eastern Europe, suggests close affinities with the Ordovician genus Pseudolingula and gives god reason to assign Bicarinatina to the family Pseudolingulidae. There is no important points of difference in the morphologies of Bicarinatina and the Early Carboniferous lingulid genus Liralingua and, thus, both genera are here synonymized.
UserNote
88A-1 , Demarcation Point , Locality consists of the basal 90 m of the lower member of the Ulangarat unit. Its geographic coordinates are: Lat. 69 deg. 00.35'N, Long. 143 deg. 21.65'W; and it is located in the SW1/4, NE1/4, SE1/4 of sec. 17, T5S, R37E, Demarcation Point A-4 quadrangle. At this locality, the basal 32 m consists of green-gray-weathering mudstone, which is overlain by black phyllite with sporadic fossiliferous calcareous siltstone and fine-grained sandstone interbeds. The specimens of Bicarinatina were recovered from throughout the mudstone interval. (description from Popov and others, 1994, p. 1215). (=locality 16 of Reiser and others, 1980, USGS Map I-1133).

No Data , Demarcation Point , The same species has also been noted in the basal 44 m of the Ulungarat unit type section (locality 2 in Figure 1), but was not collected. Its geographic coordinates are: Lat. 69 deg. 01.6'W; Long. 143 deg. 10.6'W; center N1/2, SE1/4, NW1/4 of sec. 7, T5S, R38E, Demarcation Point A-4 quadrangle.
