Taklamakania

Extinct genus of trilobites

Taklamakania is a genus of asaphid trilobites of the family Raphiophoridae that lived during the late Caradoc of Inner Mongolia, China. Like all raphiophorids it is blind, with a headshield that is subsemicircular, carrying genal spines and a forward directed spine on the central raised area, with the front of the glabella inflated and the natural fracture lines of the cephalon coinciding with its margin. It is easily distinguished from most other raphiophorids by the 3 thorax segments. Pseudampyxina, Nanshanaspis, and Kongqiangheia also have only 3 such segments, but all three lack the frontal spine that emanates from the glabellum of Taklamakania species. All other raphiophorid genera have at least 5 thorax segments. Three species, T. tarimensis, T. tarimheensis, and T. xinjiangensis, have been assigned to this genus so far.
