Quasibeothuka Wang in Wang, Cheng & Zhang, 2008

Quasibeothuka Wang in Wang, Cheng & Zhang, 2008: 399.

TYPE SPECIES. — Quasibeothuka fusiforma Wang in Wang, Cheng & Zhang, 2008 ( Wang et al. 2008: 399, pl. 1, fig. 1-4).

AGE AND LOCATION OF TYPE MATERIAL. — Ordovician, Kurutag region, Xinjiang, western China.

TAXON CODE. — 274.

STATUS. — nomen dubium (herein).

DIAGNOSIS. — “Hollow spongy shell fusiform, ovate and elliptic. Small pores are on shell surface. There are two rod-like polar spines, one more robust, cone-shaped and other delicate, longer.” (Wang in Wang et al. 2008: 399).

REMARKS

The type material figured by Wang et al. (2008) is very poorly preserved and on none of the figured specimens is it possible to discern the characteristics that define this putative genus.
