"Not with that sail."

Baryonyx is an extinct genus of 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 (8.25 feet) high at the hips. However, studies in the fossils of Baryonyx indicate that it had not yet reached its adult stage, so it could be larger, and another study found that there were vertebrae a little larger than others, which would indicate a possible candle or hump in the adult specimen.
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 crocodilians), 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, paleontologists 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.
InGen created five Baryonyx in the InGen Compound in Isla Sorna. It was planned to live in its own paddock for Phase I of Jurassic Park, but never made it to Isla Nublar. Its paddock was located near a river, which could have supplied its residents with fish to eat.
Jurassic Park III
When Dr. Alan Grant asked Billy Brennan what kind of dinosaur they saw, Billy thought it was a Suchomimus, because of its snout, Dr. Grant said it wasn't and said bigger, Billy thought Baryonyx but he confirmed they both don't have a sail.
InGen recreated this dinosaur for Masrani Global Corporation's new dinosaur park Jurassic World. The artwork on the website had proto-feathers on the back of their arms and on the top of their heads. They were brown with yellow stripes on their backs, legs, and underbelly, a aquamarine eyespot and brown patches on their body and stripes on their tail. While mostly accurate, the paintings neural spines were too short. It lived alongside its relative Suchomimus in the Cretaceous Cruise.

"How is this better?!"

It is revealed that there are some surviving Baryonyx populations on Isla Nublar, but will now face a new danger, alongside many other creatures, in the form of an erupting volcano. By 2018, water poisoning and increased acidity caused by toxic emissions from the volcano were predicted to kill populations of aquatic creatures such as fish, endangering species such as the Baryonyx.
These variants are much different from the real-life counterparts and the Jurassic World website painting. These clones have a crocodilian-like armored back and crocodilian-like underbelly, a long but broader snout that narrows as it reaches the tip of the snout, a less pronounced notch in the upper jaw, lacks the triangular crest on the top of its nasal bones, pronated wrists like all of InGen's cloned theropods, second and third fingers being longer, claws on the second and third fingers being longer and up to the length of its thumb claw, and more straight and conical teeth. The coloration is mostly a drab grey with greyish black on the back with turquoise sprinkles all over its back, with a creamy white belly, and turquoise blue on the eye orbit.
One individual was seen walking out of a sewer tunnel, as it is about to attack Claire Dearing and Franklin Webb in the control room as lava is pouring in. Despite being pelted with lava, it remains unfazed and determined to get to its potential prey. Before it could attempt to devour them both, Claire and Franklin manage to lock it inside the underground control center, where it would have likely met its demise by the surging lava. Another individual was seen and was transported by helicopter to the boat.
At least three Baryonyx were captured to be sold off at the Lockwood Manor Auction. Two Baryonyx were briefly seen escaping the estate with all the other dinosaurs, while another one that was bought at the auction was last seen being loaded onto a cargo plane to be delivered to its buyer. It is unknown what happened with this last specimen.
Behind the scenes
Baryonyx was originally supposed to be the main antagonist dinosaur of Jurassic Park III and a logo depicting it as well as a storyboard featuring this dinosaur was even made. But Baryonyx was replaced by its larger relative Spinosaurus in the final product. According to Ricardo Delgado, who served as a concept artist for Jurassic Park III in early 2000, several members of the Jurassic Park III would refer to the Spinosaurus as Baryonyx.
On the Jurassic World website, the icon for Baryonyx is reused from the Dinopedia of the removed Jurassic Park Institute website's article about the dinosaur.
It has been confirmed that the Jurassic World website Baryonyx is a paleoart painting artwork done exclusively for the website.

- Baryonix is not seen in the tour in the Jurassic Park film, Tour the Island website, InGen Field Journal nor InGen Field Guide. But since it appears in the brochure map, it must have been planned to appear in a future attraction.
