'''''Cambrothyra''''' (not to be confused with ''Cambrorhytium'') is a Lower Cambrian coeloscleritophoran from China. The fossils are hollow cones with porous walls that had an originally fibrous aragonitic mineralogy. These conical sclerites were generally not connected to other sclerites; only occasionally are they paired or twinned.<ref name="Moore2010">{{Cite journal | last1 = Moore | first1 = J.
