First described in 1773 as the remnants of a fish, Trachyteuthis was considered comparable to a Sepia cuttlebone by Rüppell in 1829.
 A separate genus was erected for the material in 1846 by Meyer.
 English material discovered in 1855 was termed Coccoteuthis latipinnis; this was later synonymised with the identical Solnhofen deposits.
 A 2007 survey of museum collection established that there were ground for the erection of three species within the genus.
