• They should not be confused with sawsharks (order Pristiophoriformes) or the extinct sclerorhynchoids (order Rajiformes) which have a similar appearance, or swordfish (family Xiphiidae) which have a similar name but a very different appearance.
• The extinct families Sclerorhynchidae and Ptychotrygonidae had long, serrated rostrums very similar to those of extant sawsharks and sawfishes, and their relation to them has been debated.
• While it had a long rostrum with large denticles similar to sawfishes and sawsharks, its closest living relatives are actually skates.
• A 2023 study found it to be a squalomorph shark; one analysis placed it closest to angelsharks and sawsharks, but the authors concluded that its exact position within Squalomorphii is ultimately tentative due to a lack of unambiguous supporting traits.
• Sclerorhynchoidei is an extinct suborder of rajiform rays that had long rostra with large denticles similar to sawfishes and sawsharks.
