Oh. I've just found the title of a 2002 German Palaeo-conference lecture as part of the "Coleoid Cephalopods Through Time: Neontological Approaches to their Palaeobiology in the Light of the Fossil Record" by D. T. Donovan, L. A. Doguzhaeva & H. Mutvei called:
"Trachyteuthis (Upper Jurassic): two pairs of fins and their phylogenetic significance"
My headache just got worse.
And another at the 2003 Mainz Palaeontology conference, a couple of weeks ago, by Fox , D. called "The fossil Trachyteuthis Vth MEYER, 1846 (Coleoidea, Cephalopoda) a taphonomisches, morphologic and phylogenetisches problem (lecture)
Positive migraine now.
Let's just say it had fins.
