Belonechitina sp. 2 ( Fig. 5I View Fig )
Material: One flattened and incomplete specimen.
Description: Te specimen with a short columnar chamber. Te flanks are convex. Tere are no shoulder, flexure, and neck. Te aperture is broken, and the base is round and squashed. Te wall surface is covered by short spiny ornaments.
Measurements: Measured data based on one specimen.
Comparison and remarks: Belonechitina without flexure and neck, its chamber is conical, gradually transitions into the aperture, and the surface is ornamented with short spines ( Jansonius, 1970). Although Belonechitina sp. 2 , Belonechitina aspera Nestor, 1980 reported by Butcher (2009), Loydell et al., (2003, 2010), Männik et al. (2015), and Nestor (1994), and Belonechitina filose Geng et al., 1997 reported by Geng et al. (1997) all have conical chambers, the present study considers them to be different taxa. Te base of Belonechitina sp. 2 is round and convex, while the others are blunt. Due to the specimen we obtained is incomplete, the present study tentatively assigns it to Belonechitina sp. 2 .
Locality and stratigraphic horizon: Specimen was found from the Unit 2 of the Majia section.
