Baryonyxes are most known for their fearsome claws, crocodile-like jaws, long neck, and  Spinosaurus-like bodies (minus the sail). These theropod dinosaurs are known by their type species, the Baryonyx walkeri.

  • They’re named by paleontologists Angela Milner together with Alan Charig. The name was in honor of the fossil collector who discovered the holotype specimen, William Walker.
  • The species walkeriwas found by William Walker in 1983.
  • Its fossils were found in England at Surrey’s Smokejack Clay Pit. It took six years to free all the bones from the rock.
  • Additional specimens aside from the holotype have been found too. There were teeth discovered from others areas like the Isle of Wight, England, and Papo Seco Formation, Portugal.

Have you ever seen a gharial? The Baryonyx looked just like that. These dinosaurs looked like prehistoric gharials with larger bodies, fearsome long claws, and a menacing snout. But don’t go just yet because here are more intriguing details about the Baryonyx’s physical features.

The Baryonyx Rocked a Heavy Claw

Did you know that Baryonyx means “heavy claw” in Greek?  The claw was so large that you can’t miss it! The Early Cretaceous dinosaur’s hand had three fingers with one sporting a large claw that was 12 inches long. Paleontologists suggest that the long claws were used to catch fish when they hunted for meals.

The Baryonyx Sported Sharped Jagged Teeth & Preyed on Fish and More

What’s more perfect for hunting delicious fish than with perfectly serrated teeth, a long jaw, and a narrow snout? Its long claws helped break down the big prey it caught.

Then its lower jaw helped the upper jaw grip the fish using its numerous teeth. The dinosaur’s adaptations let it hunt fish by the riverbanks anytime, no problem. It’s also the Top 8 Swimming & Water Dinosaurs.

Interesting Baryonyx Stomach Contents

  • Fish scales were found in the holotype specimen’s stomach. This made it the first dinosaur identified as a fish-eater.
  • Did you know a juvenile iguanodontid’s bones were also found in the holotype specimen? This fish-eating dino discovered in England could then be one of the Early Cretaceous’ meat-eating dinosaurs too.

The Baryonyx Was a Heavy-Weight Champion

Are you wondering how big is a Baryonyx? This fish-eating dinosaur grew as big as 33 feet long and weighed as heavy as 3,800 lbs. But is a Baryonyx bigger than a T. rex? Most likely, no.  The T. rex was taller and larger. It stood at around 42 feet and weighed up to 16,000 lbs.

Are Spinosaurus and Baryonyx Related?

Yes! The Spinosaurus is the Baryonyx’s close relative as they belong to the same family –Spinosauridae.

Baryonyx & Spinosaurus' Common Family Features

  • This family is known for skulls that are like modern crocodiles. Crocodile-like jaws and pointed teeth are characteristic of Spinosaurids.
  • Some like the Baryonyx even had a small crest on their heads. This small crest stood out because of the sharp triangular shape that was different from other closely-related spinosaurids.

Baryonyx & Spinosaurus Important Connections

  • Since it was discovered in England, this fish-eating dinosaur helped paleontologists understand the Spinosaurus better though the latter was discovered many decades earlier.
  • Other family members of the Spinosauridae, which were originally thought of as crocodile fossils, became more easily identifiable because of the Baryonyx.

Can the Baryonyx Swim?

Paleontologists Alan Charig and Angela Milner suggested that the Baryonyx could swim. But it may not have lived an aquatic lifestyle because of its nostrils that were far from the tip of the snout and were set on its sides.

Did Baryonyx Hunt in Packs?

We haven’t discovered studies yet that prove that Baryonyx hunted fish in packs with its large claws. If they did, that would be quite a scene!

But even if they didn’t, their life is already awesome and teaching about its life wouldn’t be any less fun. Take the fun up a notch with realistic Baryonyx puppets that make the prehistoric creature come alive.

Is Baryonyx Intelligent?

We can’t say for sure but the Natural History Museum shares a good rule of thumb.

The Encephalization Quotient: Determining a Dinosaurs' Intelligence

  • Paleontologists compare the size of the dinosaur’s brain to its body mass.
  • Then they take the shape inside the dinosaur’s skull (endocast) where the brain used to be to determine its volume.
  • Finally, they use living animals as a baseline which will give them a rough measure of the Baryonyx’s intelligence.

When Did the Baryonyx Go Extinct?

Countries Where Baryonyx Lived

  • In the mudflats of prehistoric England which were surrounded by marshes. Other dinosaurs that lived in the same area were Iguanodons and sauropods among others
  • And in the lagoons of ancient Portugal where it shared the place with other dinosaurs like the Megalosaurus and Mantellisaurus. The Baryonyx enjoyed a subtropical climate in these places.
