 Hello dear users of the Fossil Forum!
Please help me to identify the fossil. I'm inclined to think it's a cuttlefish Gladius.  Am I right?

LOCATION: Russia, Volgograd city area

ASSEMBLAGE: the Finds in this place are shark teeth: Squalicorax pristodontus (Agassiz, 1843), Pseudocorax affinis Agassiz, 1843,  Palaeohypotodus bronni (Agassiz, 1843), Cretolamna appendiculata (Agassiz, 1843)

DISCOVERY: the Gravel bed.
Thank you.
