Cathaymyrus
''Cathaymyrus'' is a genus of Early Cambrian cephalochordate known from the Chengjiang locality in Yunnan Province, China. Both species have a long segmented body with no distinctive head. The segments resemble the v-shaped muscle blocks found in similar cephalochordates such as ''Amphioxus''. A long linear impression runs along the "back" of the body looking something like a chordate notochord. ''Cathaymyrus'' is related to ''Pikaia'', another cephalochordate from the Burgess Shale. ==See also==
