Apart from its apparently taller sail, Suchomimus was very similar to the spinosaurid Baryonyx from the Barremian of England, and shared traits with it such as the reduced size and increased amount of teeth behind the snout tip in the mandible than spinosaurines, strong forelimbs, a huge sickle-curved claw on its "thumb", and strongly keeled ...
