Spinosaurus (15 m) was far larger than Baryonyx (7.5 m), though both belonged to the spinosaurid family.

Baryonyx had a massive 31 cm thumb claw; Spinosaurus also had enlarged hand claws adapted for gripping fish.
Spinosaurus lived in North Africa; Baryonyx was discovered in England, showing spinosaurids had a wide geographic range.
Baryonyx is among the best-understood spinosaurids due to its well-preserved stomach contents (fish scales).
