The type vertebrae, despite the tall and thick neural spines, share a few characters in common with corresponding vertebrae of Piatnitzkysaurus, Sinraptor, Yangchuanosaurus, and Metriacanthosaurus. So it should be provisionally classified in Sinraptoridae, pending discovery of better material. The only known specimen of  Becklespinax  is a set of three articulated and very distinctive dorsal vertebrae with elongate neural spines.
