Thelxiope is a genus of
Cambrian and
Ordovician
arthropod. Four named species are known, the type species T. palaeothalassia is known from the
Burgess Shale, Canada
[1] T. holmani is from the
Wheeler Shale of Utah, Thelxiope tangi from the
Linyi Lagerstätte of
Shandong, China, and T. spinosa, which is known from both the
Linyi Lagerstätte and the Wheeler Shale. An indeterminate species is also known from the Ordovician (
Floian)
Fezouata Formation in Morocco.
[2]
[3] It is a member of Mollisoniida, alongside close relatives
Mollisonia,
Corcorania and
Urokodia. They are suggested to be stem-
chelicerates.
