Classification: Saurischia. Theropoda. Spinosauridae.
Genus: Baryonyx (“Heavy Claw”)
Species: B. walkeri
Due to its unique snout and the size and shape of its teeth, it is believed that Baryonyx mostly hunted fish. It is believed it hunted similarly to the modern day Gharial, a crocodile relative with a very long, thin snout that catches fish by swinging its nose side to side in the water.
It is believed that Baryonyx and its relatives may have been semi-aquatic, spending much of their time in and around water.
Baryonyx likely walked on two legs and could grow to about 30 feet in length.
The first claw on each of its hands was very large and curved, giving the dinosaur its name, which means “Heavy Claw”.
Its snout was long and thin with many teeth, like that of a crocodile. This is a trait it shares with others of the Spinosauridae family, like Spinosaurus and Suchomimus. The narrow snout and a hooked tip, and often had a small crest above the eyes.
LENGTH: Between 7.5 and 10 meters (25-30 feet)
WEIGHT: Between 1.2 and 1.9 tons (1.3-2.1 short tons)
Baryonyx lived about 125 million years ago, in an environment that likely consisted of mud flats, lagoons, and marshes. It may have existed in the same time and place as dinosaurs like Iguanodon, Polocanthus, Neovenator, and Hypsilophodon.
