Baryonyx is a type of dinosaur that lived a long, long time ago. It had a long snout with lots of sharp teeth, which it used to catch fish. Baryonyx also had very long claws on its hands that helped it catch fish too! It was a big dinosaur, but not as big as some of the other ones you might have heard of, like T. rex or Triceratops. Baryonyx was a special dinosaur because it was one of the few that liked to swim and catch fish in the water.
