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

- 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).
