Schizorhiza is an extinct genus of schizorhizid sclerorhynchoid that lived during the Late Cretaceous.

[4] Schizorhiza stromeri was named by Wilhelm Weiler in 1930 for rostral denticles from the Nubian Sandstone of Egypt.

[5] Schizorhiza is characterized by its robust rostrum with over 1,800 denticles arranged in dense batteries, which form a continuous cutting edge along each side.

[6] Among sclerorhynchoids, this denticle arrangement and replacement system is only found in Schizorhiza and its close relative Harranahynchus.

[7] The rostrum was likely used for swiping and slicing prey like sawfishes[5] and has earned Schizorhiza the common name of "slasher ray".
