Albino version is coming soon.

Baryonyx is a Spinosaur, a member of the same group as the northern African dinosaurs Spinosaurus and Suchomimus. Baryonyx was smaller than these relatives but was still a big predator. It was 10 meters (33 feet) long and 2.5 meters (8 feet) high at the hips. It had a long, narrow snout filled with teeth that were cone-shaped - a real difference from the blade-shaped teeth of typical meat-eating dinosaurs.

Because of the shape of its snout and teeth (both of which are similar to those of modern crocodiles and alligators), some paleontologists think that Baryonyx ate lots of fish. Others, however, think it ate other dinosaurs. In fact, both ideas are supported by the original Baryonyx specimen from Surrey, England. In the guts of this dinosaur, palaeontologists found the partially digested scales of large fish as well as the partially digested bones of a young Iguanodon. This strongly supports the idea that Baryonyx ate both fish and dinosaurs.

Unlike dromaeosaurids, the creature had a long curved claw on the thumb of each hand, rather than on its hind legs. This claw measured at about 30.4 cm (12 in).

The skeleton was not arranged exactly as it would have been in life (articulated), so the paleontologists reconstructing it placed them on the front feet because these legs were so powerful. The bone structure suggests a massive bulk of muscle ran down the sides of these front legs, and it therefore seems probable that the claws were placed here.

The long neck was fairly inflexible, and was not S-shaped as in many other theropods. The skull was set at an acute angle, not the 90° angle common in similar dinosaurs. The long jaw was distinctly crocodilian, and had 96 teeth, twice as many as its relatives. Sixty-four of the teeth were placed in the lower jaw (mandible), and 32 large ones in the upper (maxilla). The snout probably bore a small crest.

It is speculated that Baryonyx would sit on a riverbank, resting on its powerful front legs, and then sweep fish from the river with its powerful striking claw. This is similar to the modern grizzly bear. The long but low stance and angled head support this theory.

Until the discovery of the closely-related Suchomimus, Baryonyx was the only known mostly piscivorous (fish-eating) dinosaur. On the other hand, bones of an Iguanodon were also found in association with the Baryonyx skeleton. A definitive proof, it seems possible that Baryonyx scavenged or killed any extra meat it could find. A more clear proof directly pointing that Spinosauroids aren't obligate piscivores as previously thought.
