''Taklamakania'' is a genus of trilobites that lived during the late Caradoc. Like all Raphiophorids it is blind, with a headshield (or cephalon) that is subsemicircular, carrying genal spines and a forward directed spine on the central raised area (or glabella), with the front of the glabella inflated and the natural fracture lines (or sutures) of the cephalon coinciding with its margin. It is easily distinguished from most other raphiophorids by the 3 thorax segments. ''Pseudampyxina'' and ''Nanshanaspis'' also have only 3 such segments, but both lack a frontal spine. 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 sofar. == Etymology == The generic name ''Taklamakania'' refers to the Taklamakan desert, the area where its fossils were found. The species epithet ''tarimensis'' is also a geographic derivation, now from the Tarim basin, which includes the Taklamakan desert.
